Q. Polonium (84Po210) emits 2α4 particles and is converted into lead (82Pb206). This reaction is used for producing electric power in a space mission. Po210 has a half-life of 138.6 days. Assuming an efficiency of 10% of the thermoelectric machine, how much Po210 is required to produce 1.2×107 J of electric energy per day at the end of 693 days?
Given masses of the nuclei Po210=209.98264 amu, Pb206=205.97440 amu, α4=4.00260 amu, 1 amu×c2=931 MeVAvogadro number= 6×1023.
