Over 83 million people around the U.S. live in residences with radon levels over the EPA's action level, new data reveals.

The Gilbert U-238 Atomic Energy Laboratory set is referred to as the "world's most dangerous toy," according to the Interesting Engineering portal. The set has just been put up for auction ...

In its natural state, it consists of three isotopes (U-234, U-235 and U-238). Other isotopes that cannot be found in natural uranium are U-232, U-233, U-236 and U-237. The table below shows the ...

Beginning in the late 1950s, the U.S. met this challenge by developing nuclear batteries known as radioisotope thermoelectric generators (RTGs) and producing plutonium-238 (Pu-238) as their fuel, ...

Nuclear reactors that use heavy water can employ a form of uranium commonly found in nature (U-238) rather than requiring so-called enriched uranium, which contains a higher percentage of easily ...

The proposed solution to this problem is to instead use fast-neutron reactors, which “breed” non-fissile uranium-238 into plutonium-239 and plutonium-240, which can then be used as fresh fuel.
