in radiation protection standards (for example, the NRC revised 10 CFR Part 20 in part based on recommendations and models described by the International Commission for Radiological Protection in ICRP Publications 26 and 30).10 In addition, since 1979, the NRC has promulgated regulations for radioactive effluent and environmental measurements for other types of facilities, including shallow land disposal facilities in 10 CFR Part 61, independent spent fuel storage facilities in 10 CFR Part 72, and gaseous-diffusion, uranium-enrichment facilities in 10 CFR Part 76. Collectively, these advances to the scientific and regulatory framework have caused some of the nomenclature and references in the 1979 version of Regulatory Guide 4.15 to be inconsistent with current NRC and industry concepts. Finally, Federal agencies in the United States with responsibilities for protecting the public from harmful effects of radiation (including NRC) have been cooperating in a multi-agency effort to standardize the approach to radiation protection measurements. This program has produced MARSSIM and MARLAP, and NRC guidance should be updated to reflect these efforts and endorsements. 11 See glossary. DG-4010, Page 18 2. Objective This revision reflects generally recognized advances in radioactive effluent and monitoring techniques and methodologies; contemporary radioanalytical sampling and measurement concepts; current references and guidance, consistent with industry and interagency standards and practices; and recent changes to NRC regulations. To ensure that radiological monitoring measurements are valid, defensible, and appropriate for their intended use, organizations performing these measurements have found it necessary to establish QA programs. These programs are needed to identify and correct deficiencies in the sampling and measurement processes and to obtain a known measure of confidence in the resulting data and subsequent decisions. Quality assurance should be applied to all
