Title: Technical Change to Dose Methodology
Abstract: The purpose of this action is to make a technical change to the dose methodology used in subpart A of 40 CFR 191, entitled Environmental Radiation Protection Standards for the Management and Disposal of Spent Nuclear Fuel, High-Level Waste and Transuranic Waste. The current methodology is outdated. The dose methodology used in the rule published on September 19, 1985, was based on the target organ approach recommended by the International Commission on Radiological Protection (ICRP) in Report #2. Since that time science has progressed and a new methodology based on an effective dose equivalent approach is currently being recommended by the ICRP in Report #26. This action would propose updating the 40 CFR 191, subpart A dose limits published in 1985 from the target organ to the state-of-the-art effective dose equivalent system. There would be no change in the level of protection, just the scientific methodology for determining compliance with the levels of protection established in 1985.
