A proposed framework for consistent regulation of public exposures to radionuclides and other carcinogens

This paper discusses a proposed framework for consistent regulation of carcinogenic risks to the public based on establishing de manifestis (i.e., unacceptable) and de minimis (i.e. trivial) lifetime risks from exposure to any carcinogens at levels of about 10-1-10-3 and 10-4-10-6, respectively, and reduction of risks above de minimis levels as low as reasonably achievable (ALARA). We then discuss certain differences in the way risks from exposure to radionuclides and other carcinogens currently are regulated or assessed which would need to be considered in implementing the proposed regulatory framework for all carcinogens.
