This study reports the occupational radiation doses for external exposure received in 1999 by the radiation workers monitored by the Radiological Protection and Nuclear Safety Department (DPRSN) in Portugal. Occupational exposures arise from conventional industry, research laboratories, the health or medical sector, and mining. There are no nuclear power plants in the country. There are two dosimetry systems running simultaneously at DPRSN, one based on film dosimetry and the other on thermoluminescence dosimetry (TLD). In 1999, 8400 persons were monitored, 3100 with film and 5300 with TLD and the data presented in this report were obtained by using both technologies. The annual mean effective doses received from external radiation in the different fields of activity and the distribution of the annual effective dose by dose intervals are presented. The collective annual dose by field of activity is estimated and the contribution to the total annual collective dose is determined.
本研究报告了1999年葡萄牙放射防护与核安全部（DPRSN）监测的辐射工作人员所接受的职业外照射剂量。职业照射源自传统工业、研究实验室、卫生或医疗部门以及采矿业。该国没有核电站。DPRSN同时运行着两种剂量测定系统，一种基于胶片剂量测定法，另一种基于热释光剂量测定法（TLD）。1999年，对8400人进行了监测，其中3100人使用胶片，5300人使用TLD，本报告中呈现的数据是通过两种技术获得的。给出了不同活动领域从外照射接受的年平均有效剂量以及按剂量间隔划分的年有效剂量分布。估算了各活动领域的年集体剂量，并确定了其对年度总集体剂量的贡献。
