摘要
对胜利石油管理局测井公司和中国海洋石油测井公司现有145枚测井用的与刻度用的密封型放射源表面放射性污染与泄漏进行了检测。结果表明,约有近半数以上的密封源受到不同程度的放射性污染。其中约有10%的密封源有较严重的放射性污染,甚至超过国家标准的有关规定,说明对测井用密封源实行定期检测具有重要的现实意义。根据初步检测结果,对今后测井用密封源的表面污染与泄漏检测提出了具体建议。
The superficial contamination and leak detection of 145 sealed radioactive sources used in Sheng-Li oilfield and China Offshore Oil Logging Corporation have proved that about 50% of the sealed radioactive sources was superficially contaminated in some degree, 10% of which was more seriously and even exceeded the national standards, so it is important to make regular detections of the sealed radioactive sources. Accordingly, some concrete suggestions how to do the detections are given herein.
