我们展示了一种实用的校准方法及其对商业放射性光致发光剂量计(RPLD)的适用性，即GD-352M(AGC Techno Glass，日本静冈)，通过按照ISO建议进行校准来进行眼镜片剂量监测。然后，通过一系列实验对校准进行了验证。为了验证RPLD的定标因子(1.21±0.04，k=1)，我们在ISO窄系列X射线参考场进行了标准照射，并在某医院的实际辐射场进行了模拟测量。在验证实验中，还将基于热释光技术的商用剂量计DOSIRIS™与GD-352M一起放在了ISO圆柱体模型和兰多模型上。用GD-352M和DOSIRIS™测得的个人剂量当量Hp(3)符合较好。我们的结果证明了商业上可获得的RPLD的正确校准，该RPLD适用于医务人员对眼睛晶状体的额外监测。
We demonstrate a practical calibration method and its applicability for a commercially available radiophotoluminescence dosemeter (RPLD), i.e. the GD-352M (AGC Techno Glass, Shizuoka, Japan) to eye lens dose monitoring, by performing the calibration according to the ISO recommendations. The calibration was then verified through a series of experiments. For verification of the derived calibration factor (1.21 ± 0.04,k= 1) of the RPLD, we performed standard irradiations in the ISO narrow series X-ray reference fields and the simulation measurements in the actual radiation fields in a hospital. The TLD-based commercially available dosemeters, DOSIRIS™ was also put on the ISO cylinder phantom and the RANDO phantom together with the GD-352M in the verification experiments. The personal dose equivalentsHp(3) obtained from the GD-352M and those obtained from the DOSIRIS™ were in good agreement with each other. Our results demonstrate the proper calibration of a commercially available RPLD that is applicable to the additional monitoring of the lens of the eyes for medical staff.
