Abstract The notification of a radiological accident/incident in Portugal is very rare. This study was conducted after a suspected occupational overexposure to ionizing radiation by a radiologist whose thermoluminescent dosimeter (TLD) had exceeded the value allowed by Portuguese legislation. After verifying the facilities a biological dosimetry study using the dicentric assay was performed using the dose-response curve for the Portuguese population. Cytogenetic dosimetry confirmed the TLD value and the worker's exposure to an accidental dose of ionizing radiation. The Portuguese Directorate-General for Health imposed health surveillance for the patient and he was excluded from further professional radiation exposure for 5 years.

使用生物剂量学来确认辐射暴露：案例研究

摘要 在葡萄牙，关于放射性事故/事件的通报非常罕见。这项研究是在一名放射科医生怀疑职业过度暴露于电离辐射后进行的，该放射科医生的热释光剂量计 (TLD) 已超过葡萄牙立法允许的值。在验证设施后，使用葡萄牙人口的剂量反应曲线进行了使用双着丝粒分析的生物剂量学研究。细胞遗传学剂量测定证实了 TLD 值和工人暴露于意外剂量的电离辐射。葡萄牙卫生总局对患者进行了健康监测，他被排除在进一步的专业辐射暴露之外 5 年。
