Our interest in particles in soils stems from the strong association between some contaminants (e.g., plutonium) and particles and the potential for particle-facilitated transport of these ...
This, as he found out, isn’t something you should do lightly, as the one he used ended up containing an interesting mix of radioactive materials, including small amounts of plutonium-239 ...
Deep space exploration faces the challenge of continuous energy supply. Plutonium-238 (238 Pu) undergoes α- decay with a half-life of 87.7 years and an average ray energy of 5.49 MeV, which can ...
An invisible and almost massless particle could be the building block ... In most nuclear reactors, uranium decays into plutonium. But in order to actually make a nuclear weapon, the reactor ...
He managed to produce the disintegration of a non-radioactive atom, dislodging a single particle. The particle had a positive charge, so it must have come from nucleus: he called this new particle ...
