摘要

目的是检查辐射从业人员所穿的铅围裙的损坏情况，并通过实验测量未损坏和损坏围裙的相对传输率。对某大容量医院各科室收集的281条铅围裙进行了透视和x线扫描。使用电离室探测器和99mTc点源测量剂量率。计算了未损坏和损坏胶圈的传播率，并进行了统计评价。大的撕裂和裂缝，除了未知的1型、2型、3型和4型。只有14.5%的围裙损坏，32%的围裙在手术室单元使用。测定了未损坏胶圈的透光率为50.88%。大撕裂、裂纹、1型、2型、3型和4型损伤的传输率分别为91.30%、62.75%、53.22%、58.10%、57.88%和55.54%。研究表明，除了撕裂和裂缝等常见损伤外，各种损伤和缺陷都可能对辐射传输产生重大影响。综上所述，定期透视和x射线扫描对于探索这些无形的损伤和加强辐射工作人员的辐射防护是必不可少的。建议今后进一步研究停机坪损伤的预防措施。

Inspection of lead aprons damage and evaluation of transmission rate with a 99mTc point-source

The intent was to inspect the damage to lead aprons worn by radiation practitioners and experimentally measure the relative transmission rates for undamaged and damaged aprons.Fluoroscopy and X-ray scans were made for 281 lead aprons collected from various departments of a large-capacity hospital. Dose rate measurements were obtained using an ionization chamber detector and ^99mTc point source. The transmission rates of the undamaged and damaged aprons were calculated and statistically evaluated. Big tears and crack, besides unknown ones named type 1, type 2, type 3, and type 4. Only 14.5 % aprons were counted as damaged and 32 % were used in the operation room unit. The transmission rate of the undamaged aprons was determined as 50.88 %. The transmission rates calculated for Big tears, cracks, type 1, type 2, type 3, and type 4 damages were 91.30 %, 62.75 %, 53.22 %, 58.10 %, 57.88 %, and 55.54 %, respectively. The study revealed that aside from common damages like tears and cracks, various damages and defects may significantly affect radiation transmission. This is to conclude that periodic fluoroscopy and X-ray scans are essential to explore such invisible damages and enhance radiation protection among radiation workers. Future studies are recommended to investigate preventive measures for apron damage.
