A radiation protection survey has been carried out using TLD to assess the radiation exposure to staff during radium insertions for cancer of the cervix. The staff monitored were the radiotherapist, anaesthetist and operating theatre assistant. The radiotherapist, who received the highest exposure, had on the average 160 muGy (16 mrad) whole body (chest) dose while the finger tip doses were around 600 muGy (60 mrad) from the insertion of 60 mg radium. TLD was found to be convenient and sensitive for this purpose, including estimation of finger-tip doses. It helps to maintain the confidence of the staff that their doses are "as low as readily achievable" and also offers a means of checking improvements in practice where found necessary.
已使用热释光剂量计(TLD)进行了一项辐射防护调查,以评估在为宫颈癌患者插入镭源过程中工作人员的辐射暴露情况。接受监测的工作人员包括放射治疗师、麻醉师和手术室助理。接受辐射剂量最高的放射治疗师,全身(胸部)平均剂量为160微戈瑞(16毫拉德),而在插入60毫克镭源时,指尖剂量约为600微戈瑞(60毫拉德)。结果发现,热释光剂量计在此用途上方便且灵敏,包括用于估计指尖剂量。这有助于让工作人员相信他们的剂量“已尽可能低”,并且在必要时还提供了一种检查实际工作改进情况的方法。
