The revised international standards for radioactive waste management led by my country are released

Reporters learned today that my country-led revision of the international standard for radioactive waste management "Activity Measurement of Solid Materials Considered for Recovery, Reuse or Disposal as Non-Radioactive Waste" was released, providing general technical guidelines for the precise classification and management of radioactive pollutants around the world. This international standard is led by Chinese experts, with participation from experts from the United States, France, Japan, the United Kingdom and other countries.

A large amount of radioactively contaminated solid materials will be produced during the operation of nuclear facilities and various nuclear activities. Recycling and reusing solid materials that are not contaminated or only slightly contaminated is an important goal to promote the sustainable development of nuclear energy.

This international standard divides measurement methods into on-site measurement and laboratory analysis, and develops differentiated technical methods. On-site measurement can quickly and directly determine a single contaminated material, while laboratory analysis can accurately and effectively screen materials with complex contamination. On the premise of ensuring accurate and reliable measurement results of contaminated materials, it can reduce the workload and technical threshold of material screening, reduce manpower and capital investment, avoid the risk of cross-contamination during the indiscriminate measurement of a large number of contaminated materials, and improve the economy and safety of material screening.

The release of this international standard is an important practical achievement in my country's promotion of green upgrading of the nuclear energy industry. It marks that my country's practical achievements and technical level in the screening of slightly radioactive pollutants have been internationally recognized, and will effectively promote the green, low-carbon and sustainable development of the global nuclear energy industry.
