Radiation exposure was prospectively measured using film dosimeters worn at the lapel and dominant wrist for up to three two-month intervals in 18 emergency physicians and residents, and was compared to that received by 18 radiology technicians and 18 first-year house staff during similar periods. While all levels were well below maximum permissible doses for occupational exposure, the mean lapel exposures for a two-month period were 14 mrem for the emergency physicians, 26 mrem for radiology technicians, and 7 mrem for the house staff. The difference between the latter two was statistically significant. At the wrist, emergency physicians had a mean of 43 mrem; radiology technicians, 25 mrem; and house staff, 5 mrem. The difference between the first and third groups was statistically significant. No correlation between number of exposures and exposure levels could be detected because of variation in use of protective garments, distance from the beam, and type of exposure. Procedures requiring personnel exposure include those of small children, stress views of the extremities, and studies in the multiply traumatized patient.
对18名急诊医生和住院医生使用佩戴在翻领和惯用手腕处的胶片剂量仪前瞻性测量辐射暴露情况，为期长达三个两个月的时间段，并将其与18名放射技师和18名第一年住院医生在相似时间段内所接受的辐射暴露进行比较。虽然所有水平均远低于职业暴露的最大允许剂量，但急诊医生在两个月期间的平均翻领暴露量为14毫雷姆，放射技师为26毫雷姆，住院医生为7毫雷姆。后两者之间的差异具有统计学意义。在手腕处，急诊医生的平均暴露量为43毫雷姆；放射技师为25毫雷姆；住院医生为5毫雷姆。第一组和第三组之间的差异具有统计学意义。由于防护服的使用、与射线束的距离以及暴露类型的不同，未检测到暴露次数与暴露水平之间的相关性。需要人员暴露的操作包括对小儿的操作、四肢的加压视图以及对多处创伤患者的检查。
