Equipment for continuously monitoring radioactivity in gaseous effluents. Part 3 : Specific requirements for noble gas effluent monitors

This standard specifies the special requirements for monitoring instruments designed to continuously monitor the release of radioactive gases into the atmosphere, focusing specifically on noble gases. It addresses the technical and operational criteria necessary to ensure the reliability and accuracy of such monitoring systems in various facility settings. The document outlines performance characteristics, calibration methods, and safety considerations relevant to the detection and measurement of radioactive noble gas emissions. It serves as a technical reference for the design, manufacture, and testing of equipment used in nuclear facilities and related environments where the control of airborne radioactivity is critical. By establishing clear guidelines, the standard supports consistent implementation of monitoring procedures across different installations. It covers aspects related to instrument sensitivity, response time, and the ability to distinguish between background radiation and actual releases. The content is intended to facilitate the effective management of radioactive emissions and contribute to the overall safety framework for nuclear operations without compromising operational efficiency.
