Scope

This document specifies the monitoring equipment, implementation of monitoring, data processing, and quality assurance for the point-online monitoring of γ radiation dose rates in surrounding water bodies during accidents at nuclear power plants and other nuclear facilities. This document is applicable to the point-online monitoring of γ radiation dose rates in surrounding water bodies during accidents at nuclear power plants and other nuclear facilities, and can also be used for the R&D and performance requirements of equipment for online monitoring and control of γ radiation dose rates in water bodies. At present, the radioactive monitoring of water bodies in the nearshore waters surrounding nuclear power plants in China is still mainly conducted by manual sampling, which suffers from low working efficiency and long detection cycles. In the event of an emergency, it is easy to cause radiation harm to monitoring personnel. In recent years, through the introduction of foreign equipment and independent innovation, some domestic ecological environment testing institutions and nuclear power plant operators have equipped and used a variety of online radioactive monitoring equipment for seawater. However, there are significant differences in equipment specifications, functions, and technical indicators. There are also no standards for the monitoring scope, deployment requirements, and data processing methods during daily monitoring and emergency use in the event of a nuclear accident, which greatly restricts the development of new technologies and the promotion and application of new products. Based on current technical specifications, this document clarifies the technical requirements and operating norms for point-online monitoring equipment for γ radiation dose rates in water bodies through research and development and testing experiments in the nearshore waters surrounding nuclear power plants. This document can also be used to guide the R&D and practical work of e
