The maximum permissible workday dose for occupational exposure to radiation is 12 mrem. A 83 kg laboratory technician absorbs 1.7 mJ of 0.2 MeV gamma rays in a work day. The relative biological efficiency (RBE) for gamma rays is 1.00. The number of gamma-ray photons absorbed by the technician in a workday is closest to:
a. 2×10^9
b. 5×10^10
c. 5×10^8
d. 2×10^8
e. 5×10^9
