I was a 1980s goth. I’ve been avoiding sunlight for 40 years.
can i see your veins through your translucent skin? i'm asking for a friend. (he's a vampire)
"Goth" is a 90's word, so...
In the 1980's you either avoid the sun entirely or fry their skin as much as possible lol
Comparing to other people of your cronage, can you notice differences about your skin?
@@TotalDec LOL no.
Never understood why people want to use tanning beds, I will never lay down in the cancer bed
On this night, I pray to the Engagement God of RUclips by leaving a comment and bumping your Engagement.
All seriousness though, great video. I appreciate the story, and warnings against UV Exposure.
Yeah, those tanning beds are really dangerous since the people who use them go there multiple times.
Going Once may be fine, but getting ur skin from white to brow/black is just stupid and dangerous.
I'll take the vitamin D synthesis and nitric oxide synthesis tho.
Probably because they want to get tanned Sherlock

That also has it's own set of risks.
Sitting under a UV light for warmth gives 2001 Lia radiological accident vibes.
Three men looking for firewood in snow covered forest in Georgia stumble across 2 metal canister radiating heat. They proceeded to use them as a heat source and getting radiation poisoning because they were radioisotope thermoelectric generator.
Pretty brutal story with me hearing about it from Kyle Hill and Plainly Difficult
that’s fascinating and horrifying!
Poor dudes :(
Yeah. I know the accident. The poor guys must stayed at hospital for 2 years to heal their wounds. One of them never get back home. As fas as the heater there was about 1 minute shifts for workers who get it out of forest. Another 300 heaters were later found all over Georgia !!
That almost sounds impossible after the Goiana tragedy in the 80s. I figured they would keep close track of any nuclear material. Edit: ah, *that* Georgia.
This was a great video, nicely written with just the perfect amount of prerequisite information. However, I feel like that security guard was failed, even despite is ineptitude. At one time, companies would have proper training and a guard would be part of staff, and not some kind of contractor unknown to the rest of a lab. They might even have proper training and healthcare afterward.
@@veccio The more I look for signs of it, the more I see that working people everywhere are being abused in this system.
Thank god, someone finally actually gave a proper explanation of how UV is damaging despite not being ionizing.
Thank you so much, this was really informative, and scratched an itch I've had for years now!
Thanks!
UV, and even visible light, is ionizing(!!!) The reduction potential to dissociate water is 1.6 eV, corresponding to a wavelength of 775 nm which is at the edge of Near IR. Thymine dimers just happen to be alot more effective at mutation than free radicals in a cell because said free radicals are rapidly quenched by superxode dismutase, peroxide dismutase, etc, whereas thymine dimers are a direct action on the DNA.
@@tetrabromobisphenolDo you have a reference for that actually working? I'm sure the dissociation energy corresponds to that wavelength but that doesn't mean it will dissociate the water. Chemistry and physics is a lot more than just thermodynamics.
Also the label "ionizing radiation" is a bit misleading, there's plenty of unstable compounds that can react with "non ionizing" or visible light.
Doesn't help that some UV wavelengths are just soft x-rays.
@@tetrabromobisphenoljust no.

You should always consider getting any weird moles checked. Melanoma is a very curable cancer if you catch it early. Though it is rare you should still keep a bit of an eye out for any weird looking lesions on your skin.
This. Some signs that a mole might be melanoma are if it's assymetric, unusually shaped or if it growing.
Skin cancer (aside from just Melanoma) is the most common cancer in the US and melanoma causes the majority of deaths…mainly because it’s so often overlooked. Quite literally seen and disregarded as a mole, Get that stuff checked out!!

Yes, and you should ESPECIALLY do that if you had made it your habit to doze unter a UV light for months.

Five months ago, a medical university in Romania accidentally left an UV lamp on for an entire day while students were studying. Around 20 students later arrived at the hospital with retinal burns and skin injuries. Some have permanent damage, some are blind. Due to corruption in the country, no one has been held accountable.
A yes, "justice" in eastern europe 👉 🤡🤡🤡
"He's exposed himself to lethal radiation! Quick, fire him for sleeping on the job!"
Only WE can expose you to lethal radiation, serf!
What else were they supposed to do? Keep a lazy security guard that sleeps on the job and completely ignores giant warning signs saying not to expose yourself to the UV lamp inside the room? He was unfit for the job and would have been fired whether a UV light was involved or not.
@@jeremy5602 fire him, but definitely tell him about his now-increased risk of skin cancer so that he goes and seeks treatments. They probably didn't tell him about it so that they wouldn't be responsible for his treatment.
I thought the "naps between rounds" meant that he's not currently working. Given there's no picture of the warning, I think it's unfair to assume it was obvious.
@@jeremy5602yes. I’m also confident that’s what the cancer dude employers were thinking. 😂
Not that they would soon have a deathly ill employee to drain their company health insurance benefits
my brain is so cronically broken that when i saw the electron move i unironically though "hehe, radiation makes electron angry"
such a great comment
No no ur brain is perfect
It's that modern day humor, and I love it. I'll have to explain heat to people like that lol
Me thinks happy not angry but either way
This is so adorable
Damn they really did that guard dirty. It's not like he knew or did it on purpose but better to cut all ties asap than to later be forced to pay settlements.
He broke rules and disregarded a warning sign.
yep, this is what I was told
@@shinola228 The institute also broke the rules because such a system is inherently unsafe without interlocks and keyed switches and proper training was not carried out. Any VALID training program requires testing to ensure that the employee understood all of the material. If an HVAC tech were to go in there to fix something and accidentally turn on the UV source he could have gone blind or gotten cancer too. It's incredibly stupid and unethical to put all of the blame on the guard. The family of the guard would have an easy time in court suing over this, the institute was highly negligent.
Sleeping on the job alone is likely enough reason to fire a security guard, though. Giving himself a lethal dose of radiation over several weeks of sleeping on the job routinely was icing on the cake.
Yeah, they could've explained the dangers to him at least. Melanoma is treatable if caught early. I wonder if he'd still be alive if they had told him to look out for it in the coming months/years.
That is horrifying to think about. Taking a short nap in a warm room turning into getting cancer.
There needed to be an interlock switch system. Also a bright red flashing warning light. Seriously. This should have been the Safety Officers responsibility in the first place.
He did it for several weeks though smh
They fired him purely because they didn’t want to pay for his inevitable cancer treatment or provide his family any compensation. He wasn’t trained properly or warned of the dangers, meaning the employer was at fault. He could’ve sued them, so I’m sure they failed to mention the likely outcome of all that exposure before they quickly shoved him out the door.
File under: psychopathic management stories.
@@Pushing_Pixels . That room and UV lighting had no warning or safety interlocks. Owner/operator are absolutely guilty of safety dereliction.
Imagine being stupid enough, to not read the warning, and stay in a place where you have a light of a strange color that produces heat 🤔
So you mean a company fired a low rank worker for failing to comply with the safety protocol, unbeknownst to him, fully realizing he will contract health problems in near future?
I say, that company is more dangerous than "mere" uv light

I am a welder, UV is always a risk. Most other welders are too careless
Co-worker of mine said arc eye feels like getting sand in your eye, but it doesnt go away.
@@adamwyman4629arc flash eye does go away after a few days, but in the interim your eyes itch horribly and water, you can't keep your eyes closed for very long or open for very long due to the discomfort, a doctor may prescribe you numbing eye drops so you can sleep, and for a few days the cornea of your eyes will be bright red, and you will be temporarily photophobic, so you will have to wear sunglasses because you will not be able to tolerate bright light. I had it happen to me and it's definitely no picnic.
Welder here, metal dhavings, 11,000 RPM rotating wheels and 100 amps of electricity don't scare me, but a small hole in my welding hood? That's horrifying.
Yep, I'm also a welder. I never work without sleeves even if I'm sweating buckets in a hot shop.
I wish I could make some other coworkers care more, most do, but there's a few that just don't give a damn...
I really hope nothing bad happens to em.

But we need it for vit D production, and to avoid depression.
Also human eye can see UV light (as faint blue-looking color), but most of it doesn't make it through the eye lens.
just like everything else we deal with, you shouldn't over do it either way (100% avoiding it, or over exposure).
It takes a minuscule amount of sun exposure during summer to get enough vit D. For example in the UK (which has WAY less sun exposure than southern USA or southern Europe, for example) it's enough to spend 13 mins outside at noon 3 times a week to get enough, assuming you don't also get vit D from your diet in which case you need even less. If you go overboard you increase your risk of negative side effects. It's always cheaper and less risky to pay for vit D supplements than for cancer treatment. Not to mention the Ozone layer that limited the amount of UV reaching the Earth's surface is getting thinner every year.
Also that thing about most UV light not going through the eye lens is straight up misinformation. It's a clear transparent lens, it doesn't have any kind of barrier. Just because you can't see it doesn't mean it won't reach into your eyes and damage the optic nerve.
Of course, you shouldn't avoid the sun at all times, but since people are in heavy denial that the ozone barrier has degraded and the sun is no longer as safe as it was 80 years ago, we should always be mindful of how much sun reaches our body. Check UV index when you go outside, at least.
You can get 15 spf to get vit d if you gonna stay a short time outside. Vit d production has lower threshold than uv damage.. Also it is not just vit d the thing that produce vit d in our skin has immune and neurotransmitter modulator effect seperate from vitd production. You cant just take vit d and done with it body is a very complex organism.
@@exosproudmamabear558 exactly. we shouldn't be maximizing one thing (DNA damage) and forget about the rest of the system which needs light
no sunscreen is good enough or applied well enough on average to completely block vitamin D production. every expert recommends still using sunscreen nonetheless. the remaining UV making it through the sunscreen is enough for your vit D needs.
@@DasEtwas they recommended sunscreen and vit d from food and supplements. the wavelength for Vit D is UV-A and UV-B which are absorbed by sunscreen.
Back during the WOD, when Psilocybe Fanaticus used to advertise in High Times, he fruited a batch of mushrooms under UV light and damaged the genome that developed from the spores he harvested. Even generations later, albino mushrooms and mutants would develop from spores harvested from line that were fruited under UV light. He had to go back to his collection and start a new line that had never been exposed to UV in order to restabilize the genetics.
Pretty dubious claim but fungus is pretty cool.
Did he write a trip report on erowid too
I remember that. I had begun using a black light during fruiting after he recommended it. It took many batches to realize what was happening.
Fascinating.

Should be mentioned that UV can penetrate clothing and shade doesn't offer much protection either. The rays will reflect and bounce off of other objects. If you are serious about sun protection wear UPF clothing, wide brim hats, sunglasses AND sunscreen. Don't forgot to reapply it!
But it is also important to get sun exposure for a few min a day. Vitamin D absorption (=active form) in the body requires sun light. I experienced vitamin D deficiency for the first time in quarantine, and I suffered from health problems I never have encountered before. So everything is supposed to be in moderation basically.
@@user61696 Yes agreed a few mins each day is important for health!
I first learned about UV-C when watching BigClive on RUclips. He was talking about sanitation lights during the pandemic. There was this accident where UV-C tubes were being marketed as black lights. They realized there was something off when the tubes had a blue-green light rather than a violet light, but they thought it looked cool. The came down with arc flash burns on the corneas. They recovered, but it's really unpleasant.
I'm not sure why the security guard didn't have that problem. Was he wearing eyeglasses with glass lenses? The security guard should have sued because it was the lab's responsibility to tell him.
Apparently UV coatings on plastic lenses protect from UV C as well. It’s pretty uncommon to have uncoated lenses nowadays.
As for responsibility, he ignored the sign warning people to stay out with the UV light on.
Well the guard basically ignored the safety warning right on the door, so there were no grounds for him to sue on.
It wouldn't surprise me if the guard lied to avoid punishment or simply forgot. Of course, the former guard would say he did teach him when in court.
He ignored warning signs and turned on specialized lab equipment (that look nothing like ordinary light bulbs)for hours everyday for months. It's hard to imagine someone not knowing what artificial UV glow looks like. If anything, he deserves a Darwin Award.
They did tell him. With big warning signs on the walls.
This video isn't about UV-C it irrationally promotes overgeneralisation that all different types of UV are the same thing, for sponsor clicks.
Years ago, due to many overexposures to the sun, my arm developed a melanoma, which my Dr. caught.
I then had it removed by a dermatologist. He recommended that I either avoid sun exposure between 10 AM & 4 PM,
or otherwise apply SPF 30+ sunscreen if I must go out then.
Glad that you're ok now!
This further enforces my belief that security guards need to be educated in the nature of whatever they're guarding, especially in scientific facilities.
What an awesome video to watch while I got pretty badly sunburned over the weekend.
I got a pretty bad sunburn a week ago (purely due to my own forgetfulness to wear sunscreen), and my skin is still partially red and has been peeling a bit for the past couple days. Watching this video did not make me feel good at all
@@astroguy2791 quite the same, I was tomato red, peeling all over. Don’t worry though, cancer rates for people under the age of 40 is like 0.5 percent. Cancer is a much bigger issue after the age of 40, it increases exponentially.
Yet UV light is vital to our cellular processes, particularly bone and skin health. It’s a deadly dance we walk every day.
I blame evolution
Exactly. So like, where is the balance, y'know?
@@darkscienceytI mean, evolution is just “survival of the…eh, good enough”

This one hits close to me as I’ve been working under the sun for about 3 years now. Thank you
As long as you are wearing clothes and a hat maybe sun cream you’ll be fine this video is just telling you what could happen not would humans have evolved outside. You’ll be fine
I'm 65 and recently had a couple of skin cancers cut out . I told the doc it had been 40 years since I had significant sun exposure and she said it's common for it to take that long. Point being, even if you start covering up now you'll want to be on the lookout for cancer for the rest of your life.
@@Kinguk22 we did evolve in nature yes but don't forget that people in the past didn't have to care about dying of cancer, they died so early it wasn't a problem and the next generation had already been born. You and I do have to worry bercause we live much longer.
@@Danuxsy pEoPlE iN tHe PaSt
@@NathanDudani??? You good nathan
Not even a metion about UV-A B or C there is a big difference.
And what's that?
He specifically called out the wavelength range of particularly problematic UV. I think that's sufficient.
Did the guard not notice he was essentially getting sunburnt every night?
Also confused about this
Sunburn is not the result of UV light but heat from the visible light of the sun. Hope this clears the air.
@@DocEtan It's caused by UV light. Sunscreen helps block ultraviolet light and prevents sunburn. Your skin does not get hot enough to cause burns from sun exposure.
@@DocEtan
“Sunburn is caused by too much exposure to ultraviolet (UV) light. It is a radiation burn, caused when the ultraviolet (UV) rays of sunlight damage DNA in the upper layer of skin cells.”
I've always preferred the Great Indoors. I'm told that I look young for my age, so that's a nice bonus.
Never go in the sun ever. Got it!
that story at the end is absolutely horrifying to listen to. may he rest in peace, someone shoulda really told the guy before he started how dangerous UV light is. he also could've read the sign. just a tragedy all around the board.
Yes. It really wasn't his fault 😔
right and I have a feeling the sign wasn't that noticeable how can someone walk up and down a corridor and never once notice the warning sign saying not to turn the UV light on :/ or maybe he didn't understand the warning
a room like that needs safety by design. A lightswitch with a sign is not safety by design. What if the guy wasn't literate or didn't speak the language the sign was written in? A light like that needs to have its switch under lock and key. Insanely dangerous all around. I hope his family sued, and won. Because that place was totally negligent.
seems to me like the old guard is at fault for not telling the guy.
@@Genesisorginbased on this comment section it also seems like a lot of people just don't care
So we have to give up burgers & beer, wear sunscreen all day like a slimy frog, and stay out of direct sunlight for more than 15 minutes.
Sounds quite doable.
New fear unlocked
Hello! My dermatologist, and several other places I've read about skin care, says that UV skin protection is to be used not only "when it is sunny, or when you are outside in the sun". It must be applied everyday, even on cloudy/cast days because UV light/rays are not the same as visible light rays.
Let's be realistic though. We would've long gone extinct if we were to get cancer that easily
They sell that stuff.

Yes but germicidal lights are made to emit almost PURE high intensity uv-c.
Would that be a uv-a/uv-b light, the security guard would just have been a tanned security guard.

Always a good day when Dark Science uploads!
I started working in HVAC and I always bring a big sun hat with side flaps, cooling arm sleeves (easier than lathering up my arms with sunscreen every two hours) and sunscreen for my face i bought in bulk.
Not enough safety measures in place, and then fired the guard when they found out.

Thanks!
Thanks for the educational video. I had a black light when I was younger in my bedroom and loved the way people's skin, eyes and hair looked under it when it was dark outside. Was this the same thing as a sterilization light? Also I see these blue lights in some public restrooms recently and now I'm wondering how much more powerful this uv light is than what gets through the ozone layer?
I am a light bulb collector and my 2 favorite vintage bulbs are mercury vapor and fluorescent. I have several arc tubes out of both mercury vapor and metal halide lamps that the outer bulbs had been broken away on. These will still start and operate in this state, and since the quartz the arc tubes are made from (because it can handle the super high temperatures of the arc when in operation that can easily melt even Pyrex glass) this material is transparent to the full UV spectrum, which is absorbed by glass, hence these lamps having an outer glass bulb, and will cause eye irritation and damage, and skin burns if the outer glass bulb is broken. In rare cases, broken High Pressure Sodium lamps can do the same, as they contain mercury that emits UV and the ceramic arc tube is also at least partially transparent to UV. Halogen incandescent lamps are quartz and can as well, though a white hot tungsten filament emits far less UV than a mercury arc. These lamps can be a serious hazard if broken but still working! Also, clear fluorescent germicidal/ozone lamps are just as dangerous even though much dimmer than high intensity mercury and metal halide lamps missing the outer bulbs. I have these in a few sizes in my collection, and know they are dangerous as well! I used a 15 watt 18 inch diameter one I put inside of a clear acrylic tube I had cut to length that fits over the 1inch diameter T-8 germicidal fluorescent lamp to show the mercury arc that is in any fluorescent lamp but blocked from view by the phosphor to show what goes on inside these lamps. In just a few days of this demonstration, the short wave UV from this lamp cracked snd crazed badly! While it filtered out the UV making looking at it and being near it safe, the acrylic tube was destroyed. So UV is VERY nasty!! Sun lamps are either mercury vapor or fluorescent lamps with glass bulbs made of “Corex-D” glass, which is a mix of glass and quartz that can have various ratios of the 2 to provide the exact amount of a certain wavelength of UV, filtering out the more dangerous shorter wavelengths. Sperti made some portable sun lamps in the 1970’s that used a quartz mercury vapor arc tube and were causing severe UV burns because the entire spectrum was released! They were banned. Older ones used a corex-D low pressure arc tube tgat blocked the most dangerous wavelengths, much safer, but still capable of of causing UV burns. So while I collect these lamps, I am VERY aware of the dangers! Cheers!
Mercury vapor rectifiers are one of my favourite types of vintage technology!

Well guess, the TRON VIDEO GAMES MACHINE and “Skating Rings in the 80s wiil KILL US !
We use UV lights in air handling units for hospitals HVAC.
You didnt mention there are ( I believe ) 3 different bands of UV. UVA,B & C as far as Im aware UVA is the sort of UV used in nightclubs and is not considered dangerous. Im guessing UVB is on sun beds etc and is higher energy and hence can cause sun burn. UVC is like welder burn and will definitely cause skin damage, its the type used for sterilization and cleaning as it also creates ozone. Im only saying this because the general term UV is not very accurate in describing its dangers
this channel is so underrated
UV sterilization is not the same as the other stuff, though, that’s UVC
They did really bad job at making sure the new guy knows all the safety measures, then fired and in the end killed him, all that while peacefully cutting mice.

There was a sign by the light switch that said not to turn on though. The guard did this for weeks and somehow never noticed the sign is his own negligence
When something as simple as a sticker with a warning label telling you not to turn it on and you turn it on then you are well beyond deserved to get fired

Black people dont need to worry about this 😂
The best protection against UV lights is clothing, not sun screen!
No.
@@JeffVanRooy yes, it is. Sunscreen just multiplies the time it will take for your skin to be sunburnt. Clothing is a much more robust filter that will not degrade as quickly as sunscreen (provided the cloth is thick enough to block light, so a nightie will not be enough, but a good t-shirt material will be).
@@Toronado7590 You're confusing regular clothes with specifically made clothing designed to block UV light, when it comes to things like normal shirts (meaning t-shirt thick vs denim) where a regular t-shirt will provide a little (maybe 10-25 SPF) but not nearly as much protection as SPF 50 sunscreen and denim would block all but then again so would a winter jacket.
Also unless you also wear a scarf, hat, gloves and a balaclava & make sure to not get wet as well as be much hotter wandering around wearing a full outfit in the sun you should still wear sunscreen anyway.
As a redhead with blue eyes I wear clothes, a hat with at least SPF 50 sunscreen and still can't stand more than an hour in the sun. Even with all of that after an hour out in the sun I'll still be red. I hate the sun lol
@@JeffVanRooy that is what I meant by "thick enough", I could also have added "with tight enough fibers" since it is the way it works, but yeah, it is a filter, which means it does not block, but attenuates.
Good luck for the summer mate, I hate it too ^^'
@@Toronado7590 Fair enough. You too, stay safe!
Sadly I’m too stupid to understand this video. 😢

So black lights will be this era's radioactive paint?
No but seriously how does this video have so little views?
Do UV flashlights you can buy anywhere, without any warning as far as I can tell, emitt this harmfull wavelength or do they have some kind of a filter or something to not be dangerous? As an example I found one with 365nm wavelength. Sorry if it's a stupid question, I'm not very knowledgeable on this subject.
I wouldn't worry. Those uv flashlights have a larger wavelength compared to uv sources that are normally considered dangerous. There is also a lot more that goes into what makes certain sources of uv dangerous than just its wavelength as well. Radiation is not a cancer death ray. Even sources that put off a tremendous amount of radiation can be safe if you limit your exposure time to it. So you will be fine as long as you don't bask under its light all day every day.
he says that emr in the 315-400 nm range can allow these dimerization reactions, however danger should be mitigated by not pointing the flashlight at skin or reflective surfaces
What happen with other led lights, such as red, green, ..? Are they dangerous? They are being used for beauty skin.
Has no effect: Those are under the visible light spectrum, which as stated in the video, cannot affect carbon molecule bonds in any way as they lack energy to do so. Now, if you were to look at the blue glow produced by sources of ionizing radiation (Cherenkov radiation)... Same applies to the infrared: It haves far too little energy to interact with anything that we wouldn't want it to.
Having some welding experience,I knew UV could cause cancer, but never knew it was because of DNA damage. This should scare some of the welders that don't wear ppe
Also cool to learn why UV is non ionizing, but higher energy spectrum lights do
arc eye is terrifying!
It's amazing what everything your body does for you to keep you alive and healthy, makes you appreciate microbiology.
Would have been helpful to discuss the different types of UV and how the lower wavelength is more dangerous than the higher ones.
... It's a spectrum, and he literally started that. Try listening
Clean the cum out of your ears.
Yeah but uvc doesn’t get the rough the atmosphere and it has the deepest penetration of all uv light and there’s also uva and uvb which is why you need sunscreen
my dad has a UVB skin therapy light for his psoriasis. it helps slow the growth of psoriasis plaques. not everyone with psoriasis can do it because of the risk of skin cancer. the lamps in the light are so strong he can only expose each half (front and back) of his body for 30 seconds, and that’s after working up to it. he has to wear goggles as well. he’s never had so much as a weird mole! but yeah i knew how dangerous uv lights can be (blacklights are generally safe. just buy them somewhere reputable) because he always told me to NEVER play with it, and i could see the strange light under the space between the floor and the closed door his therapy lamp was in, so i always believed him.
also, when he needed to get new lamps a few years back (they take a long time to degrade, but they do degrade), the government covered it. it’s kinda cool you can get a prescription for lamp tubes and other medical equipment that costs a hell of a lot!
That feels so unfair for the security guard tho, he was never trained on the dangers of the uv light, and then he just got fired, with health hazards from work...
Fired for sleeping on the job.
Nice. I always like a spicy vid from this channel. Better still, I *ALWAYS* like before I watch
What happened to your brain damage video?
But I love my black light.
When did this guy get almost a million subs? Jeez
Modern RUclipsrs be like *Setting up spooky scary scenario* "Also here's an advertisement for a useless big tech product"
SKIBIDI UV TOILET
real shit
Anus cancer
A friend of mine used to use a skysun to erase EPROM memory chips before programming those chips again. EEPROM, that's the technology before FLASH, kids 🙂 The skysun had filters that were supposed to remove the most harmful parts of teh UV spectrum but these filters were broken and removed. Normal use of the lap was to position it in a windowless room along with the EPROMs, close the door feeding the cable under the gap of the door and switch on the skysun from the outside. One time he accidentally entered the room for just a second. The result was a conjunctivitis and and some sun-blindness ensuring he'd never commit that mistake again.
Damn hulk will kill me... I think you have to check your content once 😂😂
Could you please bring back your scientist icon from your older videos, because when I watch these videos, the narrator a.k.a. you are an afterthought because of the subject matter, where is the scientist icon from your older videos? We are forced to acknowledge your existence and I just feel that would’ve been perfect to use in this video so please consider using it a bit more
OK but who put the cancer ray right next to the light switch 🤦♂️
I assume the “accident” the guard had was with a UV-C mercury vapour lamp fitted to the wall/ceiling, those make a visible sky-blue light; unlike the purple colour filter put over the footage of the “re-enactment” seen in the video 😠, and when the quartz has not been doped = the lamp makes ozone
I've been thinking about this for a really long time thank you so much for this video!
Know let’s talk about humanity seemingly purposefully destroyed our ozone layer
Why did he Get fired its not his fault
And also he got cancer cus of it
He violated protocols and he was a security guard who was SLEEPING on the job when he was supposed to be working.
@@HobbyOrganist okay I understand now
Always make sure to stay protected when I go out into the sunlight. So I always wear a condom when I'm out😂😅
Very educational, much appreciated. Just how the guard didn't get 'sunburned' at all?
Excellent explanation of the electrromagnetic light spectrum as well as UV radiation causing cancer!
So I guess we shouldn't put " the light inside the body"... as someone suggested as a cure covid? 😏
That story at the end was crazy.
Thanks for the informative material! Very understandable, and I'm no expert so that's saying a lot.
