This standard applies to radiation and use it with ionizing radiation or both surfaces of the material does not mix different densities of substances or continuous location of the interface point (single-point or multi-point) measurement of ionizing radiation level meter. The test substance may be a liquid or a solid particulate, and the output signal may be continuous or discrete.

This standard replaces GB/T 11923-1989 "ionizing radiation level meter." This standard and GB/T 11923-1989 main differences are as follows. --- Reference to IEC 60982. 1989, this standard will change the title of "ionizing radiation level meter"; --- Update and add normative references; --- Adds a number of terms and definitions; --- Delete the original standard Chapter 4, "Categories"; --- Modify the "normal operating conditions" classification and requirements (4.1.2); --- Modify the output signal switching and continuous output signal level meter, respectively, classified technical requirements listed, and "test method" row Columns are also to be adjusted accordingly (Section 5); --- Increase the electromagnetic compatibility requirements; --- Increased influence of the "external magnetic field" and "mechanical vibration" (5.3.2.4 and 5.3.2.5); --- For factory inspection and type inspection made more detailed principled provisions (6.2 and 6.3). The standard proposed by China National Nuclear Corporation. This standard by the National Nuclear Instrument Standardization Technical Committee (SAC/TC30) centralized. This standard was drafted. Shanghai Industrial Automation Instrument Research Institute, Shenzhen Metrology and Quality Inspection Institute, Institute of Nuclear Industry Standardization. The main drafters of this standard. Li Jiajia, Li Zhao name, Xiongzheng Long, Cai Zhi Wen, Zhou Ying-chun, XU Xiao Wei. This standard replaces the standards previously issued as follows. --- GB/T 11923-1989.
