目的通过对国内送检的放射防护材料和个人防护材料及用品的检测结果进行统计整理,分析我国放射防护材料的辐射屏蔽性能及防护产品质量的现状。方法整理2008年至2011年我国部分放射防护材料的检测结果,应用统计学软件分析。结果统计分析得出三种防护材料的比铅当量和主要的几种个人防护用品铅当量的平均值和分布区间。结论研究统计结果表明,我国的放射防护材料样品的屏蔽性能大部分达到或超过诊断X射线放射防护相关标准的要求。
OBJECTIVE: To analyze the radiation shielding performance of our country’s radiation protection materials and the status quo of the quality of the protective products through the statistical analysis of the test results of the domestic and foreign radiation protection materials and personal protective materials and supplies. Methods The test results of some radioprotective materials in our country from 2008 to 2011 were analyzed by using statistical software. Statistical analysis of the results obtained three kinds of protective materials than the lead equivalent and several main personal protective equipment, the average equivalent lead and distribution intervals. Conclusions The research results show that most of the shielding properties of radiation protection material samples in our country meet or exceed the requirements of diagnostic criteria related to X-ray radiation protection.
