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 ...

then some of the more common uranium 238 would be transmuted into "element 94," now called plutonium. Like uranium 235, element 94 would be an incredibly powerful explosive. In 1941, von ...

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 ...

Today, the Gilbert U-238 set is considered extremely rare. It was produced only in the years 1950 and 1951, and fewer than 5,000 units were sold in total. The set is not only exceptionally rare ...

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 ...

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, ...
