摘要

The ionising radiation will occur in many different forms of energy levels such as α, β,γ, and neutrons. The unit for an absorbed dose is 1 Gray equivalent to the classical 100 rad. The relative biological effects of the different types of radiation differ. For roentgen, β and γ-rays the relative biological effect is 1, for neutrons it may vary from 5-20 and for a-rays it is 20-40. The unit for the biological effective dose in man is Sievert equivalent to the classical 100 rem. One Sievert is 1 Gray x Relative Biological Effect, for a population exposed to a radiation hazard the term used is Collective Effective Dose. If 1 million people are exposed to 0.001 Sv, the collective effective dose is 0.001 ×10~6 = 1000 man-Sv.
