CNNC 404 Achieves Fully Domestic Krypton Isotope Thickness Source

China National Nuclear Corporation's subsidiary CNNC 404 has achieved a breakthrough in radioisotope technology, completing the transition of isotope thickness measurement sources from import dependence to fully domestic production. Krypton isotopes are important radioisotopes widely used in industrial thickness measurement, instrument and meter calibration, and tracer monitoring.

The successfully developed krypton isotope thickness measurement sources hold independent intellectual property rights and cover multiple specifications, allowing them to match the requirements of different industrial thickness measurement applications. Such products are indispensable in quality control for high-end manufacturing sectors including new energy batteries, specialty paper and thin films, providing support for the sustainable and high-quality development of high-end manufacturing.
