Afluence of thermal neutrons is 6.5 x 10" d c m 2in a layer of muscle-equivalent tissue 0.1 gkm4 thick. what is the absorbed dose at the middle of the layer?
assume that the above neutron fluence is approximately uniform throughout
a tissue sphere 5 cm in radius, due to thermalization of a field of intermediate- energy neutrons penetrating the sphere. what is the absorbed dose at the center resulting from thermal-neutron-capture y rays? how does it compare with the total absorbed dose that results (directly or indirectly) from the thermal neu- trons?
