摘要/Abstract

摘要： 利用数字X射线摄影技术(DR)对传统含铅材料的X射线防护服进行完整性检测,可以直观看出防护服是否存在缺陷。依据IEC 61331标准,建立窄射线束X射线铅当量测量条件,选取部分X射线防护服对其无缺陷和缺陷处进行铅当量测量。结果表明:选取的X射线防护服中实际铅当量大于或等于标称铅当量的占多数,测量值比标称值低5.4%以上时,认为该防护服达不到标称铅当量,其达标率为67%;防护服缺陷处的铅当量出现不同程度的降低,相比无缺陷处铅当量降低了10%~21%。

关键词: X射线防护服, 窄射线束条件, 铅当量

Abstract: While nuclear technology is widely used in medicine, radiation protection is becoming more and more important. X-ray protective clothing could provide patients and healthcare workers with direct protection, in which the radiation shielding performance directly determines the protection efficiency. Integrity testing of X-ray protective clothing made of conventional lead-containing materials using digital radiography (DR) can visualise whether the clothing is defective. According to the IEC 61331 standard, conditions for the measurement of lead equivalent of narrow beam X-rays were established, and some X-ray protective clothing was selected for the measurement of the lead equivalent at defect-free and defect areas. The results show that the actual lead equivalent of the selected X-ray protective clothing is greater than or equal to the nominal lead equivalent in the majority of the cases, while the lead equivalent at the defect areas of the clothing is reduced to different degrees.

Key words: X-ray protective clothing, narrow-beam geometry, lead equivalent
