Stringent standards of hygiene must be applied in medical institutions, especially at operating blocks or during interventional radiology procedures. Medical equipment, including personal dosemeters that have to be worn by medical staff during such procedures, needs therefore to be sterilised. In this study, the effect of various sterilisation procedures has been tested on the dose response of extremity rings and of eye lens dosemeters in which thermoluminescent (TL) detectors (of types MTS-N and MCP-N, respectively) are used. The effects of medical sterilisation procedures were studied: by chemicals, by steam or by ultraviolet (UV), on the dose assessment by extremity rings and by eye lens dosemeters. Since it often happens that a dosemeter is accidentally machine-washed together with protective clothing, the effect of laundering on dose assessment by these dosemeters was also tested. The sterilisation by chemicals is mostly safe for TL detectors assuming that the dosemeters are waterproofed. Following sterilisation by water vapour, the response of these dosemeters diminished by some 30 %, irrespectively of the period of sterilisation; therefore, this method is not recommended. UV sterilisation can be applied to EYE-D™ eye lens dosemeters if their encapsulation is in black. The accidental dosemeter laundry in a washing machine has no impact on measured dose.
医疗机构必须采用严格的卫生标准，尤其是在手术室或介入放射学操作期间。因此，包括医护人员在此类操作过程中必须佩戴的个人剂量计在内的医疗设备都需要进行消毒。在本研究中，已对各种消毒程序对使用热释光（TL）探测器（分别为MTS - N型和MCP - N型）的四肢剂量计和眼晶状体剂量计剂量响应的影响进行了测试。研究了通过化学方法、蒸汽或紫外线（UV）进行的医疗消毒程序对四肢剂量计和眼晶状体剂量计剂量评估的影响。由于剂量计经常会与防护服一起意外被机器洗涤，因此也测试了洗涤对这些剂量计剂量评估的影响。假设剂量计已做防水处理，化学消毒对TL探测器大多是安全的。经水蒸气消毒后，这些剂量计的响应会降低约30%，与消毒时间无关；因此，不推荐使用此方法。如果EYE - D™眼晶状体剂量计的封装为黑色，则可进行紫外线消毒。剂量计意外在洗衣机中洗涤对测量剂量没有影响。
