Dose in this report is an abbreviation of effective dose equivalent of radiation. This is a way of putting all types of ionising radiation on an equal basis in terms of their potential to cause harm (dose equivalent) and taking account of the susceptibility of various tissues and organs to radiation (effective dose equivalent). It is measured in Sieverts (Sv) (NRPB, 1989).
