On September 17, news emerged that CNNC 404 Co., Ltd., a subsidiary of the China National Nuclear Corporation (CNNC), has made a significant leap forward in radioactive isotope technology. China has now achieved full indigenous production of krypton isotope sources specifically designed for thickness measurement. Krypton isotopes play a pivotal role in various industrial applications, including precise thickness measurement, instrument calibration, and tracer monitoring. Their importance is particularly pronounced in quality control processes within high-end manufacturing sectors such as new energy batteries, specialty paper production, and thin-film manufacturing.

CNNC 404 has successfully developed a range of krypton isotope thickness measurement source products, each boasting independent intellectual property rights. These products are tailored to meet the diverse needs of different industrial thickness measurement scenarios, thereby providing robust support for the sustainable and high-quality growth of China's high-end manufacturing industry.
