Preliminary studies on effective and eye lens doses of six Radiologists, four Cardiologists have been conducted for a period of 3 months. Electronic dosemeters positioned under and over lead apron of staff were used for the dosimetry. The estimated effective dose per month to Cardiologist and Radiologist were 0.01-0.07 mSv and 0.03-0.14 mSv, respectively. The estimated eye lens doses per month to Cardiologists and Radiologists were also 0.15-0.30 mSv and 0.53-3.39 mSv, respectively. The effective doses per month to staff were below the ICRP acceptable limit of 1.67 mSv/month but the upper limit of the range of estimated eye lens dose exceeded the ICRP acceptable limit by a factor of 2. Regular use of protective goggles and consistent eye lens dose monitoring is encouraged at the hospital for dose optimization.
对六位放射科医生和四位心脏病专家进行了为期三个月的有效剂量和眼晶状体剂量的初步研究。使用放置在工作人员铅围裙下方和上方的电子剂量计进行剂量测定。心脏病专家和放射科医生每月的估计有效剂量分别为0.01 - 0.07毫希沃特和0.03 - 0.14毫希沃特。心脏病专家和放射科医生每月的估计眼晶状体剂量分别为0.15 - 0.30毫希沃特和0.53 - 3.39毫希沃特。工作人员每月的有效剂量低于国际辐射防护委员会（ICRP）可接受的每月1.67毫希沃特的限值，但估计眼晶状体剂量范围的上限超过ICRP可接受限值两倍。鼓励医院定期使用防护眼镜并持续监测眼晶状体剂量以优化剂量。
