- The biological damage caused by differing types of radiation varies
according to the rate of energy deposited in the body. It is useful in
a health physics instrument if its response takes into account the
biological affect of the radiation.
- Bonner et al took spheres of polyethylene with a small LiI
scintillator at their centre and looked at the energy dependence as a
function of the diameter of the sphere.
- In any field of neutrons there will be a range of energies present,
thus the problem is to devise an interaction by appropriate value of
Q.
Dose(Sv) = Absorbed dose (Gy) x Q
