After a risk analysis has been completed by the radiation safety officer, all entities where a source of ionizing radiation is present must established a monitored or controlled zone containing the source. When exposure exceeds the maximum regulatory dose, a dedicated color-coded controlled (yellow or orange) or restricted zone must be established. All assessments performed by the RSO should reflect normal working conditions. From these results, workers can be divided into two categories, A or B, based on their level of exposure. The workers should undergo medical and dosimetric follow-up with the use of passive dosimetry. The use of operational dosimetry should be added when working in a controlled zone. A radiation dosimetry report for each worker should be available to the occupational medicine provider to ensure appropriate dosimetric monitoring.
在辐射安全官员完成风险分析后,所有存在电离辐射源的场所都必须划定一个包含该源的监测区或控制区。当暴露超过监管最大剂量时,必须划定一个专门的、有颜色编码的控制区(黄色或橙色)或限制区。辐射安全官员进行的所有评估都应反映正常工作条件。根据这些结果,可将工作人员按暴露水平分为A或B两类。工作人员应使用被动剂量测定法接受医学和剂量测定随访。在控制区内工作时应增加使用操作剂量测定法。职业医学服务提供者应能获取每位工作人员的辐射剂量测定报告,以确保进行适当的剂量测定监测。
