recall the differences between contamination and irradiation effects and compare the hazards associated with these two
recall the differences between contamination and irradiation effects and compare the hazards associated with these two
explain why the hazards associated with radioactive material differ according to the half-life involved
describe the different uses of nuclear radiations for exploration of internal organs, and for control or destruction of unwanted tissue
recall that some nuclei are unstable and may split, and relate such effects to radiation which might emerge, to transfer of energy to other particles and to the possibility of chain reactions
*knowledge of the term nuclear fission
for fission to occur the unstable nucleus must usually first absorb a neutron*
describe the process of nuclear fusion
knowledge that mass may be converted into the energy of radiation
