Mass of neutron 1.0087 1u 931 MeV (e) A sample of radioactive caesium-137 with a haf life of 30 years emits f particles, each with an average energy of 0.5 MeV. The source has an activity of 2 x 1015 Bq and is used to provide power for a generator. Calculate the maximum initial power output (in Watts) of this generator, and the maximum power possible 20 years later [15 Marks] Turn Page Over PHYS002501 Waves and Particles January 2016
