recall the differences in the penetration properties of alpha particles, beta particles and gamma rays
recall the differences in the penetration properties of alpha particles, beta particles and gamma rays
recall the differences between contamination and irradiation effects and compare the hazards associated with each of these
describe the different uses of nuclear radiations for exploration of internal organs, and for control or destruction of unwanted tissue
explain how ionising radiation can have hazardous effects, notably on human bodily tissues
explain why the hazards associated with radioactive material differ according to the radiation emitted and the half-life involved
