Response to Request to Provide Assistance in Establishing Emergency Criteria Applicable to Elevated Indoor Radon Concentrations. Structures Built on the Reading Prong

摘要

On September 4, 1985 Mr. Sheldon Mayers, the Acting Director of the Agency's Office of Radiation Programs, requested the assistance of the Science Advisory Board in establishing emergency criteria applicable to elevated indoor radon concentrations in structures built on the Reading Prong. (1) Is a range of relative risk coefficients of 1.2 to 2.8 percent a reasonable range for the Agency to use in evaluating the risks associated with exposures at and above various alternative interim emergency action levels for the Reading Prong. (2) Are there any special considerations that should be taken into account in calculating the risks associated with short-term exposures to radon decay products versus lifetime exposures.
