A survey of the literature was conducted to establish the anticipated ranges of exposure to both physicians and patients during cardiac catheterization. A brief explanation of a technic for using time-lapse photography and a computer model for exposure calculation is presented. The thermoluminescent dosimeter (TLD) results used as controls for exposure values calculated by the developed technique are presented in detail. Physician eye exposures of approximately 20 mR per cardiac catheterization procedure were measured, which would suggest a limit of five procedures per week for physicians. The average patient skin entrance exposure of 28 R is high, as is the 12 mR gonadal exposure; however, they are accepted because of the possible benefits of the procedure.
开展了一项文献调查，以确定心脏导管插入术期间医生和患者预期的辐射暴露范围。简要介绍了一种使用延时摄影的技术和一个用于计算辐射暴露的计算机模型。详细列出了用作所开发技术计算的辐射暴露值对照的热释光剂量计（TLD）结果。测量发现，每次心脏导管插入术医生眼部的辐射暴露约为20毫伦琴，这表明医生每周的操作限值为五次。患者皮肤入口处的平均辐射暴露为28伦琴，性腺辐射暴露为12毫伦琴，这一数值较高；然而，鉴于该手术可能带来的益处，这些数值是可接受的。
