历史与现状自从发现射线以来已有九十多年,至今它与X射线一样已成为无损检测的重要手段。早在1896年,即伦琴发现X射线的第二年,法国物理学家贝克勒尔发现了金属铀射线,1898年居里夫妇发现镭射线,这些射线最后被定名为“γ射线。” History and current situation It has been more than ninety years since the discovery of the ray. So far it has become an important means of non-destructive testing, like X-ray. As early as 1896, the second year Roentgen discovered X-rays, the French physicist Becquerel discovered the metal uranium rays. In 1898, the Curie and his wife discovered the laser rays, which were finally named “gamma rays.” "
