A particular radioactive source produces 150 mrad of 2 MeV gamma raysper hour at a distance of 1.0 m.

(a) How long could a person stand at thisdistance before accumulating an intolerable dose of 1 rem?

(b) Assuming the gamma radiation is emitted uniformly in alldirections, at what distance would a person receive a dose of15 mrad/h from this source?
