Question
Except for this isotope, the waste water released from the Fukushima Daiichi nuclear power plant is treated to remove all radionuclides. For 10 points each:
[10m] Identify this isotope produced by cosmic ray on atmospheric nitrogen as observed by Willard Libby. This isotope is not dangerous externally, but is hazardous when ingested via food or water.
ANSWER: tritium [or hydrogen-3; prompt on T; prompt on hydrogen]
[10e] Tritium mainly decays by emitting a positron or an electron, meaning that its mode of radioactive decay is denoted by this Greek letter. Wolfgang Pauli postulated the existence of neutrinos from studying this mode of decay.
ANSWER: beta
[10h] A few grams of nuclear fuel such as a tritium-deuterium gas is injected before detonation of a fission bomb in this process to increase the yield of the fission. This process allows for the miniaturization by eliminating the pusher.
ANSWER: boosting [or boosted fission weapon]
