    Bananas are radioactive due to potassium 40 which is one very special isotope. It is both a beta emitter, and (very rarely) a positron emitter. When you observed the strange phenomenon around the banana I got giddy with excitement because I thought you might have been so absurdly lucky and observed positron annihilation. Now this is almost certainly not the case, probably just an artifact of dust or something. but I can have my fantasies!

    First of all, cool project. One modification I would suggest is to have a magnetic field perpendicular to the surface. Since electrons are negatively charged their tracks would turn clockwise around the magnetic field lines, while alpha particles are positively charged so they would turn counter clockwise. That would be a nice way for you to more easily distinguish between the two particle types. You could perhaps buy neodymium magnets and place between the coolers, just make sure they are pointing in the same direction.
    I'm not sure where in Sweden you guys are, but in some regions there are naturally occurring radon gas which is radioactive so if you have the cloud chamber in a poorly ventilated basement you might see more activity than if you are in a better ventilated room. You could also test the soil since there might be some trace radioactive isotopes in it from the Chernobyl nuclear disaster. Alternatively test the meat of wild boars, since they like to dig in the ground and eat roots they might be radioactive with isotopes from Chernobyl. After all, it was the Swedish nuclear power plant Forsmark that where first outside the Soviet union to detect the disaster due to the wind blowing from the south east on that faithful day in 1986. Furthermore, there are regions in Sweden with uranium in the ground, so you could consider testing some rocks (I know that there are some uranium ore in Slotsskogen in Gothenburg), however that might be considered illegal mining of uranium so check the laws first.
    In conclusion you guys have many interesting things you could test with you cloud chamber.

We used CO2 'snow' to achieve the very cold temperatures (it was my job to make it, by jetting CO2 from a big cylinder into a cloth bag!). Seeing actual particle trails was always a wow moment, never got tired of seeing it. The little chambers we used had a built in radioactive source for alpha and beta.

    One super easy and cheap way to get something radioactive in Sweden is to go to a second hand store like Erikshjälpen or Myrorna and go to the glassware section. There’s usually some uranium glass there, which is how I started my collection of it. They’re not marked as such though so you have to use a UV flashlight on them to tell if they’re actually uranium, they have a certain glow.

    I have made a TEC cloud chamber in the past and here is something i learnt, if you add an electric field it makes the particle tracks much more defined, around 2-5Kv does the trick. I would recommend buying a bug zapper tennis racket, removing the internal PCB and connecting the negative high voltage terminal to the cold plate and then add a wire mesh above the cold plate that the positive terminal connects to, in mine it was around 100mm above, yours may vary. if you have this on a switch you can turn it on and off and compare the results.
    another thing that i found was good was to add a few layers of fabric (I used cotton felt) on top of the wire mesh and soak it in isopropyl alcohol, this will last for a long time so you don't have to keep on spraying, you can add a heating element inside of this but i didn't find that necessary.
    also the Americium found in smoke alarms is a good source of beta radiation if you are carful and want to try it. Another source of radiation is welding rods i don't remember exactly which type

    @TheFatDadKev Год назад +3

    We made these many years ago at college, and used a large syringe to draw a partial vacuum, this increased the saturation and made a lot more trails visible - you could probably do that by making your chamber a much lower volume and putting a good seal around the base (might need to use glass instead of perspex?), we soaked a small pad in alcohol which allowed us to observe for much longer (place it to one side in the chamber) and cooled the base with a cake of solid CO2 - when you pulled the syringe the chamber went from barely working to amazing visibility, when a gentle pull is kept on the syringe it could be observed for many minutes before the vacuum or alcohol were exhausted - It's good to see it work with peltier coolers, we used to throw them in the bin due to their high power consumption and poor performance on higher powered processors.

    Good on you for getting it to work with a single layer of peltiers. It was my experience that a stack of two is needed, a high current peltier cooling the hot side of a lower current peltier, which in turn cools the cold plate. The top layer doesnt contribute all that much heat to the system (with them being driven by considerably lower current than the bottom peltiers) but it greatly enhances the delta-t possible.

    I love the effect! If you tweak the voltage of the TECs a bit, you might reach a better input-power-to-deltaT point as the input power and maximum deltaT depend a lot on your setup (cooling, and thermal conductivity of the aluminum plate). Sometimes you have to reduce the power to the TECs to increase the deltaT. Sounds counter-intuitive, but that did the trick for my setup.

    I built a cloud chamber for a high school physics class. I cooled it using a block of dry ice and used a steam iron for the heating element. The alcohol vapor was finer then in your setup so the vapor trails were finer also.

    You do good work, that's really excellent. A fun thing to try in there would be an old watch with a luminous dial and hands from a junk store. If you get an old enough one you have a radium source, still radioactive even if the fluorescent material mixed into the paint has stopped working. It's a real problem for people who repair old watches, the paint flakes off and can be inhaled.

    That was so cool honestly! I just learned about cloud chambers from seeing one at the Griffith Observatory in LA!
    I’m going to try and build one soon but just use dry ice under a copper plate due to its higher conductivity and perhaps use a reptile heating mat of the ceiling of the chamber to evaporate the alcohol.
    Thank you again😊!

    Dry ice is simple, co2 fire extinguisher, wearing protective clothing, and using a silicone rubber sheet, you put the bell of the co2 extinguisher pressing down hard onto the silicone sheet and pull the trigger. the over pressure forms dry ice. Make sure there is no one below the layer of dry ice,

    For a good radioactive source you can use pure potassium chloride, which is sold in grocery stores as a dietary, sodium-free salt-substitute. One in every ten thousand potassium atoms is radioactive K-40 which decays with mostly beta decay with the electron coming off with 1.3 MeV, so that should give you a nice trace. About 10% of the decays produce a 1.5 MeV gamma. Another common source is uranium glass, also called vaseline glass. You can often find it in antique stores, in the form of vases, bowls, or goblets.. It's the beautiful chartreuse-green glass that glows a bit in UV and it's really beautiful in sunlight owing to its fluorescence. It usually contains a few percent uranium oxide. It's been made for the past 2000 years or so. It's quite safe to handle (but I wouldn't put under my pillow at night) and emits some gammas and a few betas from a mix of long-lived uranium and thorium and short-lived intermediate protactinium isotopes. Finally, you can also remove the Americium foil from a smoke detector/alarm. It contains an alloy of Americium-241. It's a powerful alpha emitter, and you'll easily see a few hundred thousand alphas/second coming off of it. It used to be you could get thorium welding rods, but they are no longer sold because of the radioactive hazard. Ditto for lantern-mantles. They used thorium oxide impregnated cotton. To use them you set them on fire, burning off the cotton substrate and leaving a delicate metal-oxide filligree which glowed brightly with a white light when the gas lantern heated it. Again, there aren't many of them left because it became illegal to manufacture and sell them when the dangers of thorium were better understood.

    Idk if you can have it shipped to your country but here in the states we have super old uranium glass. You may be able to find it at yard sales, garage sales, antique stores, flea markets, or swap meets. In regular light it can be between a canary yellow and an emerald green and is 100% radioactive you're not supposed to eat off of them.

  • @naturallyinterested7569

    Instead of putting many peltier elements next to each other, you can stack them on top of each other. This decreases their efficiency even further, but the temperature differential gets bigger. So it will take longer to cool but you can hit lower temperatures more easily.

  • @BillRemski
    @BillRemski Год назад

    You can buy a cloud chamber from educational scientific supply houses for about $20, and a trip to the ice cream shop for some dry ice is all you need for cooling. Methanol is the standard alcohol used in cloud chambers. Also, orange Fiesta Ware ceramic plates are colored with uranium oxide, as are the lenses in yellow traffic lights, so they make a handy radiation source.

  • @Jonodrew1286

    -30 degrees is pretty easy for a refrigerant for example r410a. So you'll need a couple copper pipes(like 12mm and 2mm), a compressor with a radiator for fridges, torch lighter, soldering paste and solder wire. So you'll take about 2.5 m of 2mm copper pipe, solder it to the high pressure compressor output on the radiator (you can bend it to spiral for saving space) the other end should be inserted into 12mm pipe and soldered to it(you can use a hummer for squishing the end of 12mm pipe to fit 2mm pipe into it like 10-20mm deep). So the 12 mm pipe would be at least -40 degrees Celsius and you can bend it into something like a zig zag pattern under the table to cool it down and then it goes to the input of the compressor. And finally solder all the connections. As for the refrigerant you can go to the local refrigerator or AC repair shop and ask to fill it up with the refrigerant. For such a small thing I think there'll be more than enough 200g of the refrigerant

    You can definitely buy samples of uranium glass. Even now, you can easily buy Czech beads made of uranium glass. One bead is enough to see everything. Also on Aliexpress, glass medallions containing thorium are sold. They are called "scalar energy medallion". It looks like a circle of greenish glass in a metal ring. You don't need to wear these medallions if you don't want to end up with radiation damage. And, of course, you can grow a big beautiful potassium chloride crystal and put it in your cell!

    For the cloud chamber: Rocks, particularly ones that fluoresce under ultraviolet light. They should be cheap in Sweden.
    For Simon: Cool project! A little spray insulation between those TECs might not hurt.

    You can find some radioactive material inside a smoke detector. Most household detectors contain a very small amount of americium-241, a radioactive isotope. It would be nice to see how it works with a radioactive element.

  • @dakinmaher4522

    Great work, well done. Liked & subscribed. Very interesting. This machine was originally designed to study clouds. The builder, a meteorologist asked for analysis and advice from his physicist friend, who, I believe went on to make the radiation detector.

    "It's not that easy to get your hands on dry ice"
    In Germany when I order frozen food (semi-prepared meals) online, they send it in stryrofoam boxes packed with 1-2 kgs of dry ice to keep it cold. This way I can have 'free' dry ice regularly. unfortunately I cannot store it for long, not matter how well I insulate it it evaporates in 2-3 days.
    Warning! Anybody experimenting with dry ice, make sure you don't store it inside any building, it can raise CO2 in the air unnoticedly to unhealthy levels.

    Using a polarizing filter on your camera helps to show more of the faint condensation trails. It must be used the opposite way though. Not hiding reflections, but emphasizing them.
