Progress towards new recommendations from the International Commission on Radiological Protection

摘要

There has been a hundred-year history of the uses of radiation in medicine and industry. Throughout that time there has also been advice on the need to protect people from the hazards associated with exposure. This paper traces the evolution of protection standards through the differing phases that are identified. These phases reflect changes both in scientific understanding of the biological effects of exposure and of the social and ethical standards to be applied. An analysis is then given of the reasons why the challenges to the Inter - national Commission on Radiological Protection (ICRP), especially about the linear non-threshold response model, have arisen.
