The results of five years of radiation monitoring of 590 radiation workers in Jamaica and an additional 88 in Barbados and The Turks and Caicos Islands show that the annual dose absorbed by Caribbean radiation workers is, with a single exception, well within the internationally accepted limits of 20 mSv per year. There were few cases of relatively high exposures. The dose equivalent of the radiation workers by category agrees with international trends; workers in nuclear medicine receive the highest doses and dental radiologists the lowest. The collective Effective Dose Equivalent has been calculated for each of the monitored populations and certain trends identified. The risk for development of fatal cancers from the occupational doses reported was very low. Consistent monitoring will identify aberrant conditions quickly and help maintain that record.
对牙买加590名辐射工作人员以及巴巴多斯和特克斯和凯科斯群岛另外88名辐射工作人员进行的五年辐射监测结果表明，除一例例外情况外，加勒比地区辐射工作人员的年吸收剂量均远低于国际公认的每年20毫希沃特的限值。相对高暴露的情况很少。按类别划分的辐射工作人员的剂量当量与国际趋势一致；核医学工作人员接受的剂量最高，牙科放射科医生接受的剂量最低。已针对每个受监测人群计算了集体有效剂量当量，并确定了某些趋势。报告的职业剂量导致致命癌症的风险非常低。持续监测将迅速识别异常情况并有助于保持该记录。
