A worker in a laboratory is exposed to a 370 kBq 137Cs source which emits gamma rays with an energy of 662 keV. The point source is 1m from the worker. Assume that the area of the worker’s body is 0.6 m2 and that the body has a mass of 70 kg. Calculate the equivalent dose to which the worker is exposed (per second). Assume that 20% of the gamma rays are absorbed.

Homework Answers

Answer #1

The equivalent dose is given by product of absorbed dose multiply by radiation factor. But for gamma rays radiation factor is 1. Therefore

Equivalent dose(H)= absorbed dose

Given: 1eV=1.6×10-19 Joules, 1Ci=3,7×1010 des/s. A 2 mCi of 60Co source emits two gamma rays per disintegration with energies of E1=1172 and E2=1332 keV. 10% of gamma rays emitted from the source have been fully absorbed in a cube with a 10 cm side and a density of r = 2g/cm3. The mass of the cube is m=r.V, where V is the volume of the cube. Do your calculation and circle the correct answer for: The number of gammas per...

After the Fukushima Nuclear reactor disaster, people were evacuated from the affected area, but not all dogs were. People rescued and treated the dogs to help them eliminate radioactive nuclei from their bodies. The main isotope of concern was 137 Cs, which undergoes beta-minus decay with the subsequent emission of a gamma ray. Both the beta and the gamma radiation have RBE=1, and for one decay the total energy deposited in tissue is 1.2 MeV. 137 Cs has a half...
