as for your problem with it not working, i think you're getting heat soak. -30 is barely in the range that you need. try putting insulation around your chamber sides and just film from the top. also put ice in the coolant tank. that alone will probably work. use a thermocouple to check the temperature. that's key. if it's -20, you likely won't see anything. if you can get it colder, like -40, that's when you'll see a lot. instead of using that many, use two lower power peltiers against the cold plate, then higher power peltiers on top of those. they're horribly inefficient so the second peltier has to be a lot higher power to pump its own heat PLUS the heat from the first peltier. this is called a cascade. each peltier can drop the temperature so much. but with two layers, you can get colder. i got mine down to less than -40 by doing this. (it might have been colder but my thermal camera has a maximum of -40c). oh and you're more likely to get a chain reaction if you give the particles a charge. you need a high voltage DC source. the cheap amazon bug zappers can work
Your post reminds me of another build I saw. That guy used at least two layers of peltiers to get the temperature down low enough. I'm almost sure he used a lot more than just 6, and they were stacked, for sure.
@@Kevin-ht1ox dry ice is colder but has much much less heat density than ice from water. it's a common misconception. it WILL get the coolant colder, but if it's not glycol or alcohol or a mixture of water and something like antifreeze, it'll freeze, which isn't ideal, so using regular ice is easy and will probably work great for this application. he's already really close to the sweet spot so the ice should get him there fine. if not, dry ice is an option too, but it'll sublimate REALLY fast in water, so he'll need to buy a ton of it. that said, there are video where people use dry ice as the main source of cooling, so it can be used, but in his case, putting it in the liquid will make it go poof really quickly, which is probably tricky while trying to film
The science center in Toronto had a big cloud chamber. It's fascinating to realize we are surrounded by speeding particles. Thanks for this! Great job.
Science centre in Halifax has one as well. Kids and I were playing with it while there. If it requires a static charge on the outside of the chamber, then they had that being generated somehow within an inner chamber. Come to think of it, there were thin wires running across the top of the unit (inside), if those were highly charged, that was doing it. I think I took photos, but it definitely was multiple layers of glass/acrylic between the inner chamber and the exterior cabinet surface.
One of the best weekends of my life was an anime convention/rave at the Toronto science centre. Giving us after hours access to the science centre was pretty stupid but *insanely* fun while "enhanced" 😅
What worked for mine was connecting the hv Modul of a bug zapper to the cloudchamber. Negative to the coldplate and the positive to a metal mesh under the sponges. You can find out the polarity of the hv Modul by hooking it up to an LED.
I wonder what would happen to a cloud chamber in a basement? Here in PA we're supposed to set up radon detectors to alert us in case of excessive radon.
Considering that americium-241 has a half life of 432 years or so, one can assume that your geiger counter doesnt detect alphas. Geiger tubes sensitive to alphas have a thin mica window.
I don't know much about cloud chambers, but just an idea: You are using alcohol, right? Is it possible that it evaporates over time and since it is probably not pure alcohol, the water content rises. So if you refill it, it gets less concentrated over time
I have an old marine pocket watch from my grandpa from the 1930-1940. i used to hold it in front of a Geiger counter in school. There was a very high count rate. Since then, I also want to build such a device to just see if I can see something. Since I know that the radioactive material could decay into radon gas I store the clock outside...
Would it just be easier to use dry ice instead of peltiers? I mean I like the usablity and ease of having the system always readily available, but honestly having to chill and pump fluid and never being able to achieve those lower temps seems like a lot of moving parts and work. The ice could prolly last you all day. Unless dry ice is hard to come by in your neck of the woods. Our grocery stores and welding shops have it here in Montana.
I have a bunch of clocks and watches that are pretty radioactive from the radium. The reason radium is dangerous is because your body treats it like calcium and deposits it in your bones if you end up ingesting any particles by accident(or inhaling them). So as long as they're sealed up, its generally safe. The worst one I have no longer glows, and it still puts out 42,000CPM.
Women who painted radium dials suffered horrible bone cancers because they used to lick the tips of radium paint brushes. Today we use strontium aluminate, which is not radioactive, but does not last long light to dark.
Cloud chambers are super cool! Is the chamber grounded? Should it be? Since fluffy things cause it to work again it seems like you're probably building up and wiping away charge. Could be caused by flowing water in your cooling system.
So what happens to those particles flying off. Do they evaporate or just go off and travel forever? And if they don't fade away is there any material or set of containment fields that can reflect them and bounce them around inside an object to make electricity?
They can be used to create heat- which boils water which turns a turbine - which creates electricity. And THAT is how a nuclear power plant works. All elements have a half-life, which signifies their rate of decay. Elements (and their isotopes) which have a shorter half-life, decay more rapidly - and are classified as radioactive. Look up some simple explanation videos about half-life, and also how a nuclear power plant works. This will answer all of your questions.
i think your issue with the tracks might be able to be solved with high voltage connected to the plate. It helped me and that might explain why rubbing a pool noodle causes it to work again (static)
6:58 "its so low radioactivity.... " the women painting the dials when they were produced that way (you had bigger ones for alarm- and wall-clocks too) often got ill. they licked the brushtips to get them into shape before painting.. the more you know..
You were holding the radioactive items up to the battery . The geiger tube is an m4011 ,it's glass and it is perpendicular to the battery, look though the vents on the back of the geiger counter and you can see the geiger tube.
Beta and alphas don’t penetrate a lot because they’re larger and or have a larger magnetic effect on the material they’re going through, therefore they lose energy quicker and do not penetrate so far. Gammas and neutrons penetrate pretty far since they have a low mass, or no mass at all, and no charge as well meaning they have to physically hit something to lose energy which is less likely due to their size. They can have an effect on something without hitting it however it’s not in the sense of magnetic forces it’s more of a nuclear force. Also physical contact for something like a gamma is determined on its spin and the spin of whatever its hitting so an electron with a -1/2 spin and a gamma with a -1 spin means the gamma won’t be absorbed where as if the gamma had a 1 spin it would be or if the electron had a 1/2 spin it would absorb the gamma. That’s why the objects that only produce beta and alpha particles don’t seem radioactive, you just need a radiac that is made to measure these larger massed and charged particles. Geiger counters are most commonly used because alphas and betas aren’t really a threat to people. Alphas are stopped by the layer of dead skin on your body and betas are stopped by clothing and don’t penetrate your body very far. Neutrons, electrons, and gammas are the ones that can cause serious problems at high doses which is why Geiger counters are great. A cool fact is that smoking tobacco exposes your lungs to alphas which is why lung cancer is so common in smokers and alphas do 40 times more damage than a neutron. The more you know. Also a lot of radiacs are calibrated where 100cpm is considered radioactive or higher than background. Not sure what yours is calibrated at but in my line of work 100 cpm is a pretty bad day especially if you see it spike to 200 cpm. Real bad day.
Well the sounds of any as though the case had a charge that was influencing the end result but as far as I am already see him button you're going to need to make a holder keep that eyeball tasting the vapor otherwise it just points up
I have the same giger counter and I have 4 pieces of americium from smoke detectors and it detects well over one thousand cpm you also don't need to open the part where the battery is just use bottom middle of the counter as it is right in the middle where the gas tube is and will detect more of the radiation that way while the part where you had it at was close to the tube it not a lot of radiation was able to be detected because most of it was flying off and not getting into the tube.
I noticed that there is a motion of the alcohol vapor from the back lights to the front. This could maybe be a convection current caused by the minimal but still existent heat from the lights.
Jag demonterade en elektrisk flugsmälla och kopplade den till ett nät under den kalla skivan och andra polen till ett nät uppe under glaset. Funkade riktigt bra.
there are some counters that can't do alpha particles. some do, but require you to open a door. some have a slider switch that changes the material covering the geiger tube for the three particle types. the one you have is probably just blocking alpha via the plastic shell
Careful with those watch dials...the poor girls who painted those dials back in the day got terrible radiation poisoning which led to terrible illness, injuries, and even death. One probably won't affect you, but always good to be careful...
YOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO FINALLY ANOTHER VIDEO !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! it hurts when it's so long between videos
If there aren't any videos after this, I understand. I think I am alone in this. Should you be doing this at all? What about 'professionals'? Should they be doing this? Let's play with radiation and call it a video.
Alpha and beta particles in earths atmosphere will typically be a small percentage (like 5% to 15%) of the speed of light. Beta tend to move slightly faster. Speed can greatly vary tho. The chamber temp is probably the reason for you problem. I almost guarantee the pads you were using have degraded from use and possibly amp overdraw.
Your cooling system is a big mess. You need to learn how to use Peltier coolers. You can easily cool the cold plate to -30°C with a simple water cooler used for PCs. There is no need to "cheat" with precooled liquid to offset the dT of the Peltier cooler. You also run the Peltier coolers without voltage regulation which is another issue. If you run them at full power, they will heat themselves up too much due to the Joule heating. You need to lower their input voltage. It depends on which unit you use, the input voltage may vary, but it is typically 10-12 V. 12 V is often too much if the module is a high-power one. Regarding the "failure" at the end, as others already explained, you need a high voltage potential difference across the chamber.
Be cool if you could get a mini one on a plane and compare what the background level looks like up at altitude vs here on the ground. I mean TSA will prolly search yer butthole, but it would be a neat vid.
Definitely not smart enough to understand a hint of what’s being said (science was never my strong suit in school) but I’ve always held a fascination for radiation!
Regarding your problem with the cloud chamber, I have some Ideas as to why it may not be working. Some designs have a high voltage difference between the top and bottom of the chamber to make the tracks easier to see (I think this is to excite the valence electrons of the alcohol vapor but do not quote me on that). Another thing that may help is a leak or some convection in the chamber itself. If the vapor isn't still, it could make the tracks hard or impossible to see, and if there is too much of a temperature difference, convection will occur, and obviously that is not good- this problem may be due to your dual pump change. If vapor is escaping, that cold vapor doesn't have a chance to condense. But most importantly, make sure to have a great day!
