CGN radiation monitoring ability gains IAEA accreditation


Six samples of 22 monitoring items from the Environmental Test Center of Suzhou Nuclear Power Research Institute Co Ltd were accredited as “satisfactory” by the International Atomic Energy Agency (IAEA) on Oct 12.

This means that the monitoring results the test center produces are accurate and reliable. The relative deviation between the center’s results for four kinds of fission products and three kinds of activated products, and the truth values provided by the IAEA, was below 5 percent. The smaller the figure, the stronger a lab’s analytical ability. The center’s radiation monitoring ability reaches an internationally advanced level.

The IAEA is the world’s largest radiation monitoring proficiency test provider and the most authoritative international evaluation organization in the radioactivity analysis sector. It distributes unified test samples to labs and evaluates their analysis results in order to improve the radioactivity analysis ability of member states’ labs.

A total of 267 monitoring labs in 66 countries across the world participated in the proficiency test this year. The Environmental Test Center has participated in each of the three years since 2016. It intends to improve its analysis and quality of radiation monitoring through comparison with high-level international standards.

Meanwhile, it is of great significance for CGN to showcase its radiation monitoring ability, and enhance its influence over international peers.

Founded in 2011, the test center has had 68 analytical items obtain China Metrology Accreditation (CMA), and 14 items have passed the China National Accreditation Service for Conformity Assessment (CNAS). It has the lead in China in Sr-89 and Sr-90 fast conjoint analysis technology and multi-nuclide conjoint analysis technology, which effectively cuts test costs and provides a strong technical support for the monitoring and assessment of the nuclear power plant environment.
