An anisotropic point source emits 1010 γ-rays/sec with an energy of 1 MeV. The source is surrounded by a lead shield 10 cm thick. Calculate at the surface of the shield: a) the flux in the absence of the shield b) the uncoiled flux c) the buildup flux d) the exposure rate in the absence of the shield e) the exposure rate without the buildup of scattered radiation f) the exposure rate with buildup
