本文报道了上海地区10种不同型号的工业X射线探伤机外以靶为中心,离靶1m处测出的泄漏辐射。国家工业X射线探伤机,其照射量率(均值)在5.16×10~(-5) C·kg~(-1)·h~(-1)(200mR·h~(-1))以下,除个别型号外,均在“北欧国家应用国际辐射防护建议书报告”介绍的推荐值范围之内。在X射线探伤机纵截面内不同方向上,X射线管阴极端的泄漏辐射照射
This paper reports 10 kinds of different types of industrial X-ray flaw detector outside the Shanghai area as the center of the target, 1m away from the target measured leakage radiation. In the national industrial X-ray inspection machine, the irradiation rate (average value) is below 5.16 × 10 -5 C · kg -1 · h -1 -100mR · h -1, Except for some models, they are all within the recommended values described in the Nordic Countries Report on the Application of International Recommendations for Radiation Protection. X-ray flaw detection in the longitudinal cross-section in different directions, the cathode ray tube leakage radiation exposure
