由中国核工业总公司国营四○四厂石家庄辐射技术中心仪表研究所研制的SY—5000型多功能射线吸收仪于年前通过了中国核工业总公司科技部组织的专家鉴定。 SY—5000型多功能射线吸收仪是基于不同物质对射线有不同吸收性能而设计的多用途测量仪器。与不同的一次测量装置配套可组合成下述多种核测量仪器。 射线传感器接收到的计数率随物料质量厚度的增加而减少,二者之间有确定的函数关系,由计数率得出质量厚度,是SY—5000型多功能射线吸收仪最基本的功能。
The SY-5000 Multi-function Radiograph developed by China National Nuclear Industry Corporation 440 State-owned Shijiazhuang Radiation Technology Center Instrument Institute passed the appraisal of experts organized by the Ministry of Science and Technology of China National Nuclear Industry Corporation (CNNC) years ago. SY-5000-based multi-function X-ray absorptiometer is based on different substances have different absorption properties of radiation designed multi-purpose measuring instruments. With a different measuring device supporting can be combined into a variety of nuclear instrumentation. The counting rate received by the ray sensor decreases with the increase of the material thickness, and the two have a definite functional relationship. The mass thickness obtained from the counting rate is the most basic function of the SY-5000 multi-function ray absorption instrument.
