北京市计量标准管理处同位素应用研究室试制成功了γ—射线料位计,并由北京市西城区二龙路第一金属厂正式生产。γ—射线料位计是带有放射源与核辐射探测器(计数管)的电子继电器装置。γ—射线在空气中呈直线传播,当γ—射线遇到其他介质(如液体或物料)时,由于射线与物质发生相互作用,部分γ—射线被吸收或改变前进方向,这时到达辐射接收器(计数管)的射线量减少了。γ—射线料位计就是根据γ—射线的这种性
The Beijing Institute of Metrology Standards Department of Isotope Applications successfully trial production of γ-ray level gauge, and by the Second City, Xicheng District, the first metal factory formally produced. The γ-ray level meter is an electronic relay device with a radiation source and a nuclear radiation detector (counter tube). γ-ray in the air was a straight line, when the γ-ray encountered other media (such as liquid or material), due to the interaction of the ray and the material, part of the γ-ray is absorbed or change the direction of advance, then reach the radiation reception The amount of radiation from the instrument (counter tube) is reduced. γ-ray level meter is based on this nature of γ-ray
