Unformatted text preview: [4] In 1989, two electrochemists, Pons and Fleischmann claimed to have discovered cold fusion of deuterium in an electrochemical cell. The fusion reactions lead to two possible f nal states that occur with equal probability: 2 H + 2 H = 3 He + n + 3 . 27 MeV 2 H + 2 H = 3 H + 1 H + 4 . 03 MeV (a) How many neutrons will be emitted in the generation of 4 W? (b) If 15% of these neutrons are absorbed by a 60 kg Fleischmann, and if each neutron carries an average energy of 0.5 MeV with an RBE of 4, what radiation dose rate in rems/hour will Fleischmann receive? (c) How long would it take for Fleischmann to receive a lethal 500 rem dose? 1...
