γ射线探伤是无损检测必不可少的手段之一。在国外许多工业发达的国家,如美、英,法、西德、日本等国,普遍采用γ射线探伤。五十年代,我国曾引进了苏联制造的γ射线探伤机,由于设备结构不够完善,加之缺乏使用大剂量γ射线的基本知识,以至于在使用中发生过射线探伤事故,多年来,一直影响到我国对γ射线探伤技术的推广和应用。随着我国社会主义现代化建设事业的迅速发展和对产品质量要求的提高,迫切要求发展γ射线探伤技术。 Gamma ray flaw detection is one of the indispensable means of nondestructive testing. In many foreign developed countries, such as the United States, Britain, France, West Germany, Japan and other countries, the widespread use of γ-ray detection. In the 1950s, China imported the γ-ray flaw detector manufactured by the Soviet Union. Due to the imperfect equipment structure and the lack of basic knowledge of using large doses of γ-ray, it has been affected by the use of X-ray inspection flaws for many years Popularization and Application of γ Ray Detection Technology in Our Country. With the rapid development of China’s socialist modernization drive and the improvement of product quality requirements, the development of γ-ray detection technology is urgently required.
