Standards for environmental, non-threshold, carcinogens: a comparison of the approaches used for radiation and for chemicals

摘要

Environmental standards for ionising radiation and for chemical carcinogens have been developed independently of each other. Radiation standards have been derived by deciding upon what is an accpetable risk, and then finding the corresponding dose from the exposure/risk relationship- quantitative risk assessment(QRA). The extent and the quality of the exposure/risk data for radiation, and the authority of the recommendations of the International Commission on Radio- logical Protection(ICRP), have resulted in universally accepted guidance and standards.
