摘　　要：针对β射线穿过气态物质的能量衰减规律研究的不足,文章研究了β射线穿过气态物质的能量衰减规律,并推导出其在气态物质中工况条件下的测量公式。首先在测量β射线穿过气态物质的射线量时,发现理想气体状态下的β射线能量衰减规律;其次通过气体的温度、压力(气压)、流速(风速)的变化,推导出β射线在气态物质中衰减量变化的计算公式,可以将此理论应用于相关领域的测量检测设备和检测方法中。In response to the lack of research on the energy decay law ofβ⁃rays passing through gaseous substances,the energy decay law ofβ⁃rays passing through gaseous substances was studied,and its measurement equation under working conditions in gaseous substances was derived.Firstly,when meas⁃uring the amount ofβ⁃rays passing through gaseous substances,the energy decay law ofβ⁃rays in the ide⁃al gas state is found;secondly,the formula for calculating the change in the decay amount ofβ⁃rays in gaseous substances is derived from the changes in the temperature,pressure(air pressure)and flow rate(wind speed)of the gas,and this theory can be applied to the measurement and detection equipment and detection methods in related fields.
