All you really use different from normal chemistry is much higher voltage (about million times) than for standard stuff like electrolysis. And really you won't lose any energy by doing such experiments, because only proportions are important. While it is true that you need high voltage, you also get free energy from nuclear reactions, and you can use it as heat for distillation or heating or drying. Of course dangerous just like everything.

You again?

I remember some people build fusors
I donnt think i have seen a homemade one produce neutrons
Element transmutation now that sound like fun.

The only source i could think about is americium wrapped in a sheet of lithium aluminum alloy the alpha particle passes through the aluminum and beta particle is left and combines with the lithium. Produces tritium and that fuses with the ather isotope of hydrogen.

Alpha emitters
Thorium
Americium

Alpha particle accelerator?

Just dont do a renactment of the nuclear boy scout

I found 6 lb thing of uranium ore on eBay for $44.

GG man!
now you can crush it and remove uranium, thorium and radium :)

I have a big bag about 50lbs of radioactive material. I bought it at Home Depot. :)

(spoiler: it's KCl sold as water softener. The 40K contained within makes a Geiger counter click merrily away, many times above the background)

On radioactive waste, perhaps putting it back where you got it is reasonable. The problem is when it's around unexpected places and near civilization, and that all your equipment is also said waste.

Imagesco also sells all kinds of sources. It would be really cool having a microscopic piece of polonium. Not worth the money though.

I looked at inertial confinement fusion a while back because I wanted to know how they got so many kiloamps and watts into their systems. Apparently its like a big room chock full of capacitors discharging, IIRC. Kiloamps just seemed crazy to me. Takes some pretty big wires...

Btw, homemade fusors, by way of neutron radiation, actually turn the equipment (vaccuum chamber and anything else it touches) into radioactive waste. Like, it will make the stainless steel or aluminum chamber parts emit radiation.

Smoke detectors have a bit of radioactive foil inside, usually americium. Just make a quick trip to Walmart and get a few smoke detectors. \

You can also blowtorch lantern mantles to powder and mix the powder with some lithium from a battery and wrap it in foil. Then,
drop the foil into a tin can filled with cooking oil. Finally, blowtorch it one last time. This will give you radioactive thorium.

The issue with smoke detectors is they contain less than 1 microgram of americium. They're fine as alpha* sources, but if you want sizeable amounts of americium, smoke detectors aren't a great source. Not that there's really any other options for americium though.

Sidenote, if you're in Eastern Europe, a lot of Soviet-era smoke detectors contain a small piece of plutonium. Probably the only way to get plutonium legally.

*(If I recall correctly, I'm pretty sure americium 241 is an alpha emmiter)




Carbon is overrated. Inorganic chem is where it's at.

If you want to order some thorium or depleted uranium so that you can observe their unusual and interesting chemical properties, be my guest. I don't think it's too difficult or regulated or something.

If, however, you are thinking about working with high-activity isotopes such as... anything else, stop right there.

Chemists are used to dealing with certain kinds of dangers. Usually things smell bad, or give you a headache, or bubble, or make noise, or something else. But radiation isn't like any of that. A lethal radiation injury is generally not noticeable until hours after it is too late. (Death is generally slow and painful.) And lead shielding isn't always the right choice. And if you think you're going to use a Geiger counter to keep yourself safe while working with radionuclides, you need to maybe review the Wikipedia article on what those are actually for.

That's not to say that you can't work with radiation. But if you're thinking about doing any kind of experiment with any radiation source other than 238U, 232Th or 40K, you need to set your ego down and spend a few months [at bare minimum] taking online courses until you:

- know what a characteristic X-ray is
- know the difference between Gy and Sv
- know what the attenuation factor mu and mu/rho is for common materials and where to look it up
- know AT LEAST what ion chamber, OSLD and diode detectors are, and which one you use (and how) to make sure you're not about to kill yourself
- know what kind of radiation source you're planning to work with, what kind of radiation it emits, what contaminants it produces, and how to properly contain/dispose of those
- know the local laws, procedures, and certifications required to do any of the things you're planning on doing, because fun fact, all of this stuff comes with LONG prison terms

Source: currently doing a PhD on this stuff and I wear a dosimeter when I go into work every day, don't ask me anything, I'm busy

look for Uranium glass on ebay

https://www.ebay.com/itm/Green-Vaseline-glass-dragonfly-cand...

really cheap vintage glasses with vitrified uranium oxyde
