摘　　要：对X射线移动探伤现场作业时控制区和监督区进行了计算,分别给出散射射线、透射射线、漏射射线控制区和监督区距离,其中:透射射线对辐射环境影响最大;其次为散射射线;漏射射线对辐射环境影响最小。最后对X射线移动探伤机现场作业辐射防护措施进行了讨论并给出了建议。The distance of control area and supervision area for the on-site inspection operation of X- ray mobile device is calculated in this paper. The distance of control area and supervise area were respectively given for scattered X-ray, transmission X-ray, leakage X-ray. The influence on the radiation environment of transmission X-ray is the greatest, followed by scattering X-ray. The influence of leakage X-ray is the lowest. In the end, the radiation protection measures for on-site operation of X- ray detector are discussed and suggestions are given.
