摘要
基于康普顿散射原理,利用蒙特卡罗方法模拟了伽马射线在不同油垢厚度输油管道的散射率,建立了油垢厚度与散射光子计数率的关系。结果表明伽马射线散射法用于管道油垢厚度的无损检测是可行的,其厚度响应比较灵敏。
The scattering rates of gamma-ray in different petroleum pipeline of grease stain thickness were calculated with Monte Carlo method based on the principle of Compton scattering method. The response relationship between scattering rates and grease stain thickness was found. The result showed that gamma-ray scattering method for the pipeline grease stain thickness of non-destructive testing is feasible and the thickness response of grease stain is sensitive.
