lands (AML) programs to verify and validate the condition of 2,500 defenserelated uranium mine (DRUM) sites across the nation by 2022. These DRUM sites provided uranium ore to the Atomic Energy Commission (AEC) for defenserelated activities that occurred between 1947 and 1970. Most DRUM sites are located on public lands and are abandoned.

Many tons of uranium ore have to be mined to produce just a pound of uranium, and this uranium is not pure, but mixed with oxygen. This mixture, or oxide, must then be purified to obtain pure uranium. And then even the uranium has to be purified further before it is the right kind for use in atomic bombs and nuclear power plants.

Uranium238, the most prevalent isotope in uranium ore, has a halflife of about billion years; that is, half the atoms in any sample will decay in that amount of time. Uranium238 decays by alpha emission into thorium234, which itself decays by beta emission to protactinium234, which decays by beta emission to uranium234, and so on.
