Discussion Topic 4, Updated dose/risk factors and scenarios for assessing radiological and non-radiological risk.
Since 40 CFR Part 192 was released in 1983, changes and updates have been made in the underlying science that supports radiation dose and risk assessments for this rule.
Important literature citations about some of these changes include—
- International Commission on Radiological Protection, 2008. “Publication 103 Recommendations of the ICRP, Annals of the ICRP.” Volume 37, Issue 2-4, January 2008.
- National Research Council, 2006. “Health Risks for Exposure to Low Levels of Ionizing Radiation; BEIR VII, Phase II.” Committee to Assess Health Risks from Exposure to Low Levels of Ionizing Radiation, Board on Radiation Effects Research, Division of Earth and Life Sciences. National Academies Press. Washington, DC 20001.
EPA is reviewing the existing rule to evaluate—
- potential impacts of changes in dose and risk assessment
- additional exposure scenarios
- use of different or updated computer risk models
- models that include distribution of Tribal and environmental justice communities’ population and their usage of land and resources
- impact of climate on exposure from facilities not located in the historic mining areas of the southwestern U.S.
