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

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

Your response differs from the correct answerby orders ofmagnitude. h

(b) Assuming the gamma radiation is emitted uniformly inalldirections, at what distance would a person receive a dose of10mrad/h from this source?

2

Did you accidentally divide or take theinverse in your calculation?m
