A 1.0 µCi 13755Cs source is used for 2.3 hours by a 80 kgstudent in a physics lab. Radioactive 13755Cs decays by ß- decay with a half-life of 30 years. The average energy of the emitted betas is about 190 keV per decay. The ß decay is quickly followed by a ? with an energy of 660 keV. Assuming the student absorbs all emitted energy, what effective dose (in rem) is received during lab?
