RADIATION PROTECTION IN CANADA. VII. SETTING STANDARDS FOR RADIATION PROTECTION.

The current recommendations of the International Commission on Radiological Protection have as a basic objective the limitation of the radiation dose to "that which involves a risk that is not unacceptable to the individual and to the population at large". The problem is to decide what degree of risk is acceptable, in relation to the benefits of a practice that necessitates a radiation exposure. At the present time it is not possible to make more than very rough estimates of some of the risks of exposure to radiation, but such estimates can be usefully compared with some of the other risks that are tolerated by society. On the assumption that it would be possible to make quantitative assessments of both the benefits and the risks, the question is raised as to how and by whom an appropriate balance should be made.
