Wow. I understands this professor's amazement. His great-grandfather played a pivotal role in understanding how to measure alpha, beta and gamma nucleic activity.
I have many ores and chemicals of Uranium and Thorium. I have ~5-6 grams of pure U-238 Metal (Depleted Uranium). I have other isotopes and ores, even Ekanite, a Thorium-based gemstone, and it's faceted too! This is awesome stuff... U-238 will give an extremely high reading. My Geiger Counter is digital but instead measures in µSv (Micro-Sieverts). I experiment all the time with ionizing radiation. Be careful. Use lead shielding and a respirator! This is an awesome video! 10+! Science RULES!
@echaaaa I think what he meant to say was that alpha particles have a much higher weighting factor when calculating the dose equivalent for each particular kind of radiation. You would need about 20 gamma-radiation photons to match the dose of radiation given by a single alpha particle. Alpha particles have a much higher ionising potential than gamma-rays. It's just that gamma-rays can are less prone to destabilisation that make them more lethal than alpha particles, particularly at a distance.
yes, ive been there twice so ive got some experience with this device. I didnt rly buy this cause we borowed them from the tour office but ive seen them in shops or marketplaces
@umahuma4 1000 CPM (counts per minute) are approximately 1 mrem. 100 mrem are the usual background radiation in a year. So 250 CPM are 0.25 mrem or about 1/400th of the average annual radiation.
In response to panzerkampfwagen123...he is Canadian! From Carleton! Never had a better University professor. He's a legend amongst science students for a reason.
Hi, I got the Geiger counter model series 900 mini monitor and when I do the battery check it works all fine but when I turn it on so I can do radiation readings then the needle doesn’t move at all or make a speaker sound would you be able to resolve me the problem or tell me what it can be so I can get it fixed?
I just wish he would have explained why that level of radiation (coming from those bottles) was not harmful, and just how much does it take to become harmful.
@ElricWinter The reason why gamma radiation is not harmful to us is because gamma radiation has so much energy that it just passes right through us. As for alpha & beta radiation, they have significantly less energy(B>A) & thus can be stopped easily. When alpha particles come into contact with us, they get stopped inside our bodies & thus can never get out of our bodies. During the absorbing process, alpha radiation will break chemical bonds=tissue damage & not too mention the long term effects.
What's the name of this class? BTW if Stephen didn't get laid after this class, He did his great grandfather a disservice. I agree with Ryan2588 a really great Prof.
I don't know your standing next to the great grandson of a famous man. I would be in aw. I would say, "Your great-grandfather was great man, he invented a useful item."
Man, I wish every prof. was like this guy! He's the man.
awesome that a Geiger descendant was in the class! and the professor is amazing. I wish he was my Physics prof. so enthusiastic and funny.

Amazing! 5 star video :D
Colleges need more professors like you

Awesome video! I rarely sit through long videos on RUclips, but this one was very good.

same here
i wonder what model geiger counter he is using
Very informative. Nice little 900 unit.
in Ukraine near Zone or Kiev you can buy it for even less than 75$, professional electric Geiger counter costs about 100-200
I hear it crackle all too much in that game
Uranium tablets in a bottle?
I need to find that somewhere.
And I wish he would explain the SI unit of measurement for radiation (sieverts).
Awesome demonstration.

Never had a better University professor. He's a legend amongst science students for a reason.
wow i was really into the video, it was so awesome
So how many counts does it take before things get risky?
In the future we'll all probably have to have one of these.
That video is amazing
What are the materials used in the test?

how expensive would you say his geiger counter is?
It is cool to have a Uranium ore that requires special licensing from the Nuclear Regulatory Commission.
with a Geiger counter in my hand im gonna go stake me some government land!
Bringing you the truth no matter how bad it hurts.
Was this a lesson in chemistry studies?
anybody know the best price on were I can buy a geiger counter please?
Pretty cool video!
is that yellow cake uranium
FO 3 is the only game with that quote in it..
This video was amazing!!!
That was really quite interesting!
it was really helpful...thank you sir
Great presentation. :)
There were no crickets. It was the sound coming from the Geiger counter. There was high levels of radiation
13 years, thats as old as me
I wonder if the kid passed the class?
When those Geiger counters go "click click clickety", you better get your ass outta there! XD
I just wish he would have explained why that level of radiation (coming from those bottles) was not harmful, and just how much does it take to become harmful.
Yea. Geiger was a great man.
@cl25cooldude not if you are the one handling it in a radiation field...

theres geiger counter in cod 4 too, I kept dying just wanting to listen to the clickety sound xD
What's the name of this class? BTW if Stephen didn't get laid after this class, He did his great grandfather a disservice. I agree with Ryan2588 a really great Prof.
this was great really helped with my a level revsion =D
@pibbification
just look for one on e-bay thats how i got mine.
If I read correctly, human tissue is fine unless you have 30000 or more counts per second, then yes.
You know FO 3 isn't the only fallout gmae with rad away
I don't know your standing next to the great grandson of a famous man. I would be in aw. I would say, "Your great-grandfather was great man, he invented a useful item."
Cause one dog ain't enough, and two is too low, it's me, Three Dog!
awesome really helped thanks!
Geiger counters available here: www.iboxstore.com/geiger-counter.html
its a very goodvideo :)
of course he did!
@GUARDIANtrooper ok thanks :)
4:39 You have Adv. Rad Poisoning. 6:44 You have Crit. Rad Poisoning.
he'll be fine he took 2 doses of radX in the morning
And he holds the sample right at about crotch height
@eternalfelicity lucky!
i want to shake this hand to .
'is'
Fukishima
lol, this is a bottle of radioactive material. Here hold this.
lol wow the game and this are soooo different but yes half life is like off this
Fallout 1
Watch those Geiger Counters kids, when they go Tick Tick Tickety, you better run your ass outta there, then pop some Rad-Away for good measure.
its: tick tick tickety means run your ass outta there then pop on some radaway for good measer.
Mom👩❤👩
probably in physics
Also, pop some rad-away just for good measure.
That Geiger guy is kinda cute
Im the great grandson of Joel Rinker
Test mayonnaise and pepto bismol with your geiger counter!!!! you will be shocked!
Wow 😍, why I didn't get such a good prof. Instead got some dumbguys filled with egos
Sounds just like a Geiger counter. 🤓
huh
oops ,measure.
@ggabe005 Test a bunch of bananas as well.
6 people heard click click clickity and didn't run their asses out of there
friken canadians...
I thought it was when it started beeping at you, you should gtfo.
Seriously it's overrated.
Yo, are you the descendant? Das cool man.
@@simp-slayer Yes, actually!
