�Determination of internal exposures,” to assist the uranium recovery industry on how to apply the regulatory requirement correctly at uranium ISRs. NOTE: This review was conducted in April 2017 and reflects the NRC staff plans as of that date. These plans are tentative and are subject to change. 14 Also, the guidance on how to assess the lower limit of detection contamination surveys (see Table 3 to RG 8.30, “Summary of Survey Frequencies”) should be modified using the information provided in NUREG-1575, “Multi-Agency Survey and Site Investigation Manual,” and other relevant guidance documents that include up-to-date information. 2. What is the impact on internal and external stakeholders of not updating the RG for the known issues, in terms of anticipated numbers of licensing and inspection activities over the next several years There is no impact on licensing since the NRC staff does not anticipate any new or renewal applications in the next several years. There are approximately 9 - 10 inspection activities per year over the next several years. The NRC staff expects minimal impact on the inspection activities regarding the issues discussed in item 1 above. These issues have been addressed in individual licenses (e.g., addressed in specific license conditions). In addition, other available NRC guidance documents discuss these issues such as RG 8.22, “Bioassay at Uranium Mills,” which provides guidance on “unlisted uranium materials.” Also, NUREG-1736, “Consolidated Guidance: 10 CFR Part 20 - Standards for Radiation Protection Against Radiation,” provides examples on how to comply with 10 CFR 20.1204(g). In addition, the “Supplemental Information on the Implementation of the Final Rule on Radiological Criteria for License Termination,” for 10 CFR Part 20, Subpart E, “Radiological Criteria for License Termination,” (63 FR 64132), requires licensees to monitor for beta-gamma-emitting radionuclides found in contamination at uranium
