U.S. ATOMIC ENERGY COMMISSION REGULATORY GI DIRECTORATE OF REGULATORY STANDARDS REGULATORY GUIDE 4.3 MEASUREMENTS OF RADIONUCLIDES IN THE ENVIRONMENT ANALYSIS OF 1-131 IN MILK September 1973 JIDE A. INTRODUCTION General Design Criterion 64. "Monitoring Radioactivity Releases," of Appendix A to 10 CFR Part 50, "General Design Criteria for Nuclear Power Plants," requires that means he provided for monitoring (hfe plant environs or lighl.water.cooled nuclear power plants for radioactivity that may be released from normal operations, including anticipated operational occurrences, and from postulated accidents. Paragraph (a)(2) of § 50.36a of 10 CFR Part 50 provides that technical specifications For each license will include a requirement that the licensee submit a report to the Commission within 60 days after January I and July I of each year which, in addition to specifying the quantity of each of the principal radionuclides released to unrestricted areas in liquid and airborne effluents during the last six months of operation, provides sufficient information to estimate annual radiation doses to the public resulting from effluent releases. Paragraph (e) of § 20.106 of 10 CFR Part 20 provides that the Commission may limit the quantities of radioactive materials released in air or water by licensees during a specified period of time if it appears that the daily intake of radioactive materials from air, water, or food by a suitable sample of an exposed population group. averaged over a time period not exceeding one year, would otherwise exceed specified quantities. Section 20.201 of 10 CFR 20 requires that a licensee conduct surveys of levels of radiation or concentrations of radioactive material as necessary for compliance with AEC regulations in Part 20. Paragraph (c) of § 20.1 of 10 CFR Part 20 states that every reasonable effort should be made by AEC licensees to maintain radiation exposures, and releases of radioactive materials in effluents to unrestricted
