[China achieves "national production" of krypton isotope thickness measurement sources] September 17th, reporters learned today from China National Nuclear Corporation that CNNC 404 Co., Ltd., a subsidiary of China National Nuclear Corporation, has achieved breakthrough results in the field of radioisotope technology, marking China's realization of a leap from "reliance on imports" to "national production" of krypton isotope thickness measurement sources. It is understood that krypton isotope, as an important radioactive isotope, is widely used in industrial thickness measurement, instrument calibration, tracer monitoring, etc., and is especially indispensable in the quality control of high-end manufacturing industries such as new energy batteries, special papermaking, and thin films. This time, CNNC 404 successfully developed various specifications of krypton isotope thickness measurement source products with independent intellectual property rights, which can meet the needs of different industrial thickness measurement application scenarios. This provides a solid guarantee for the sustainable and high-quality development of China's high-end manufacturing industry. (CCTV News)
