Those working in interventional cardiology are exposed to varying radiation doses during diagnostic and interventional procedures. The work presented in this paper aimed to monitor the effective doses received by different categories of medical staff members practicing interventional cardiology procedures including senior cardiologists, junior cardiologists, anesthetists and nurses. Thermo-luminescence dosimeter (TLD) badges that consisted of lithium fluoride doped with magnesium and titanium were used to quantify radiation doses. Measurements were performed with the dosimeters mounted under and above leaded aprons worn by medical staff. The results revealed that the effective doses to senior cardiologists were the highest compared to those to other participating staff members, due to their position close to the X-ray tube. The average daily effective doses for senior cardiologists, junior cardiologists, anesthetists and nurses were higher for dosimeters located above the aprons than those for dosimeters located under the aprons. Above the apron, the average effective doses accumulated during the study period were 0.44 ± 0.06, 0.34 ± 0.05, 0.29 ± 0.03 and 0.29 ± 0.04 mSv, respectively; whereas, under the apron, they were 0.20 ± 0.02, 0.18 ± 0.02, 0.17 ± 0.02 and 0.18 ± 0.02, respectively. Also, the fluoroscopy time was correlated with the dose acquired, especially for senior cardiologists. It is concluded that doses to senior cardiologists are quite high, and that many variables can affect staff exposure such as distance, direction, procedure and skills.

从事介入心脏病学工作的人员在诊断和介入手术过程中会受到不同剂量的辐射。本文介绍的工作旨在监测从事高级心脏病专家，初级心脏病专家，麻醉师和护士的介入心脏病学程序的不同类别的医务人员所接受的有效剂量。由掺有镁和钛的氟化锂组成的热发光剂量计（TLD）徽章用于量化辐射剂量。使用安装在医务人员佩戴的铅皮围裙下方和上方的剂量计进行测量。结果显示，与其他参试人员相比，高级心脏病专家的有效剂量最高，因为他们的位置靠近X射线管。对于位于围裙上方的剂量计，高级心脏病医生，初级心脏病学家，麻醉师和护士的平均日有效剂量要高于位于围裙下方的剂量计。在围裙上方，研究期间累积的平均有效剂量分别为0.44±0.06、0.34±0.05、0.29±0.03和0.29±0.04 mSv。而在围裙下，分别为0.20±0.02、0.18±0.02、0.17±0.02和0.18±0.02。同样，透视时间与获得的剂量相关，特别是对于高级心脏病专家而言。结论是高级心脏病专家的剂量很高，许多变量会影响工作人员的接触程度，例如距离，方向，程序和技能。位于围裙上方的剂量计的麻醉师和护士要高于位于围裙下方的剂量计的麻醉师和护士。在围裙上方，研究期间累积的平均有效剂量分别为0.44±0.06、0.34±0.05、0.29±0.03和0.29±0.04 mSv。而在围裙下，分别为0.20±0.02、0.18±0.02、0.17±0.02和0.18±0.02。同样，透视时间与获得的剂量相关，特别是对于高级心脏病专家而言。结论是高级心脏病专家的剂量很高，许多变量会影响工作人员的接触程度，例如距离，方向，程序和技能。位于围裙上方的剂量计的麻醉师和护士要高于位于围裙下方的剂量计的麻醉师和护士。在围裙上方，研究期间累积的平均有效剂量分别为0.44±0.06、0.34±0.05、0.29±0.03和0.29±0.04 mSv。而在围裙下，分别为0.20±0.02、0.18±0.02、0.17±0.02和0.18±0.02。同样，透视时间与获得的剂量相关，特别是对于高级心脏病专家而言。结论是高级心脏病专家的剂量很高，许多变量会影响工作人员的接触程度，例如距离，方向，程序和技能。03和0.29±0.04 mSv；而在围裙下，分别为0.20±0.02、0.18±0.02、0.17±0.02和0.18±0.02。同样，透视时间与获得的剂量相关，特别是对于高级心脏病专家而言。结论是高级心脏病专家的剂量很高，许多变量会影响工作人员的接触程度，例如距离，方向，程序和技能。03和0.29±0.04 mSv；而在围裙下，分别为0.20±0.02、0.18±0.02、0.17±0.02和0.18±0.02。同样，透视时间与获得的剂量相关，特别是对于高级心脏病专家而言。结论是高级心脏病专家的剂量很高，许多变量会影响工作人员的接触程度，例如距离，方向，程序和技能。
