Finger doses of radiologists and assistants during 19 interventional radiological procedures were measured with thermoluminescent dosimeters (TLDs), and two types of flexible protective gloves were compared with each other. There were considerable differences in doses between different sites of TLDs on fingers. The exact site of TLDs on hands/fingers should thus be reported in papers. Both gloves were also irradiated through an Alderson phantom and the attenuation values were measured. The gloves with slightly greater attenuation proved to be significantly less comfortable to use. Wearing flexible protective gloves did not lengthen screening times as compared to a previous study in the same department. Various aspects of using such gloves are discussed. The attenuation values of gloves reported by the manufacturers may not apply under all clinical circumstances.
在19例介入放射学操作过程中，使用热释光剂量计（TLD）测量了放射科医生和助手的手指剂量，并对两种类型的柔性防护手套进行了比较。手指上不同部位的TLD剂量存在显著差异。因此，在论文中应报告TLD在手部/手指上的确切位置。还通过Alderson体模对手套进行了照射，并测量了衰减值。衰减值略高的手套使用起来明显不太舒适。与同一科室之前的一项研究相比，佩戴柔性防护手套并没有延长筛查时间。文中讨论了使用此类手套的各个方面。制造商报告的手套衰减值可能并非在所有临床情况下都适用。
