The lead apron plays a crucial role in radiation protection and is extensively used in medical institutions. Periodic performance evaluations, involving visual inspections and transmission imaging, are conducted annually. This research aims to propose a performance evaluation method for 0.5 mm lead aprons used in nuclear medicine departments. The experiments were conducted using transmission imaging and source-based evaluation methods, involving two lead aprons with <1 year of use and two other aprons used for over 10 years. The experimental results indicate that using 50 kVp for transmission imaging is appropriate to detect cracks in the lead aprons. Additionally, in the case of lead aprons used for >10 years, the measured attenuation rate was found to be ~3-5% lower, depending on the measurement method. Consequently, a performance evaluation, including crack detection and actual attenuation rate measurements, should be carried out for lead aprons used long-term to ensure efficacy of radiation protection.
铅围裙在辐射防护中起着至关重要的作用，广泛应用于医疗机构。每年都要进行定期的性能评估，包括目视检查和透射成像。本研究旨在为核医学部门使用的 0.5 毫米铅围裙提出一种性能评估方法。实验采用透射成像和基于源的评估方法进行，涉及两个使用不到 1 年的铅围裙和另外两个使用超过 10 年的围裙。实验结果表明，使用 50 kVp 进行透射成像适合检测铅围裙中的裂缝。此外，对于使用超过 10 年的铅围裙，根据测量方法，测量得到的衰减率发现约低 3-5%。因此，对于长期使用的铅围裙，应进行性能评估，包括裂缝检测和实际衰减率测量，以确保辐射防护的有效性。
