Hospital based workers that perform interventional radiology are at risk of reaching the eye lens dose limit of 20 mSv/y. These workers are exposed to the radiation scattered by the patient, which creates a complex field, with low radiation energy reaching the eyes of the medical staff from wide angles. Therefore, the dosemeter used in the assessment of the eye lens dose of interventional radiologists needs to respond accurately in such conditions. In this study, the angular response of a commercially available radiophotoluminescent glass dosemeter, GD-352M, was optimized via Monte Carlo simulations, aiming at its use as eye lens dosemeter in interventional radiology. The improved dosemeter was manufactured and then characterized in terms of Hp(3), the quantity recommended for eye lens dosimetry. Its response was compared to the IEC 62387:2012 requirements for Hp(3) and to requirements proposed specifically for eye lens dosemeters used in interventional radiology. The improved dosemeter meets the IEC 62387:2012 requirements for energy and angular response for Hp(3) and also shows good agreement with the more strict requisites proposed for eye lens dosemeters to be used in interventional radiology.
从事介入放射学工作的医院工作人员面临着达到每年20毫希沃特眼晶状体剂量限值的风险。这些工作人员会受到患者散射的辐射影响，从而形成一个复杂的辐射场，低能量辐射会从各个角度到达医护人员的眼睛。因此，用于评估介入放射科医生眼晶状体剂量的剂量计需要在这种情况下做出准确响应。在本研究中，通过蒙特卡罗模拟对市售的放射性光致发光玻璃剂量计GD - 352M的角响应进行了优化，旨在将其用作介入放射学中的眼晶状体剂量计。制造出改进后的剂量计，然后根据用于眼晶状体剂量测定推荐的量Hp(3)进行特性描述。将其响应与IEC 62387:
