A person is to work in a mixed field consisting of 5mGy/h of gamma radiation, 1.0 mGy/h of beta radiation, 0.5 mGy/h of fast neutrons and 0.8 mGy/h of slow neutrons. How long can he work for without exceeding a whole-body dose limit recommended by ICRP? (The quality factors for fast and slow neutrons are 10 and 5 respectively.)
A particular radioactive source produces 100 mrad of 2-MeV gamma rays per hour at a distance of 1.0 m. (a) How long could a person stand at this distance before accumulating an intolerable dose of 1 rem? (b) Assuming the gamma radiation is emitted uniformly in all directions, at what distance would a person recieve a dose of 10 mrad/h from this source?

(Internal Exposure: Internal Radiation Dose) Given a 20µCi of 32p (T/2 = 14.3 days) is
delivered intravenously of a reference adult (70 kg). The biological half-life throughout the body
is 19 days. Calculate:
a. the absorbed dose constant (express your answer in erg/g t and Gy/t) for P-32
irradiating the whole body uniformly
b. total number of transformations that occur in the total body as a source organ; assume
that P-32 is metabolized wherein 40% is uniformly distributed to the whole body thus the initial
activity distributed in the total body is q, = 0.40 × 20µCi = 8µCi
c. the total body dose.
where t refers to the transformation number.
Note: 1 Joule = 107erg
