The half-life of uranium-238 is 4.5 billion years. It decays into radium-226, which in turn decays into radon-222. Radon-222 becomes polonium-210, which finally decays into a stable nuclide, lead.

How long does it take for uranium 239 to decay?
Uranium-239 has a half-life of about 23 minutes and decays into neptunium-239 through beta decay. Neptunium-239 has a half-life of about 2.4 days and decays into plutonium-239, also through beta decay.
How long is uranium radioactive for?
The half-life of uranium-238 is about 4.5 billion years, uranium-235 about 700 million years, and uranium-234 about 25 thousand years.
Is it legal to own plutonium?
Plutonium and enriched Uranium (Uranium enriched in the isotope U-235) is regulated as Special Nuclear Material under 10 CFR 50, Domestic licensing of production and utilization facilities. As a practical matter, it is not possible for an individual to legally own Plutonium or enriched Uranium.
Is it legal to own depleted uranium?
Typically, depleted-uranium rounds are used on armored vehicles, such as tanks and troop transports, and there is no international treaty or rule that explicitly bans their use. Depleted uranium is the byproduct of the enriched uranium needed to power nuclear reactors.
How much does a gram of plutonium cost?
It costs around $48 per gram. Plutonium is a radioactive element that can be used for research and nuclear applications. Its worth about $4,000 per gram (although you can expect various regulatory agencies to take a close look at you if you start accumulating it).
Can you legally own plutonium?
Plutonium and enriched Uranium (Uranium enriched in the isotope U-235) is regulated as Special Nuclear Material under 10 CFR 50, Domestic licensing of production and utilization facilities. As a practical matter, it is not possible for an individual to legally own Plutonium or enriched Uranium.
Can u buy uranium?
Usually when we talk about uranium round these parts, its in regards to nuclear power and weapons, as the enriched stuff is at the heart of most reactors. But even if you dont have much use for uranium, did you know you can just … buy it online, right out there in the open, and its perfectly legal? Its true!
