Radiation exposure to human beings is usually given in rems (radiation equivalent for man). In SI units, the exposure is measured in sieverts (Sv). One rem equals 0.0100  Sv. At one time, the exposure due to the nuclear reactors in Japan was measured to be 8217 mSv/h. How many rems would a person exposed to the radiation for 35 min have absorbed? If one mammogram gives off 0.30 rems, how many mammograms would that exposure be equivalent to?
