摘要

当个人剂量计不实用时,根据环境剂量当量评估个人外照射剂量对于预测和回顾性目的非常有价值。考虑到日常生活模式(在不同场所停留的地点和时间),本研究开发了一个模型,根据环境剂量当量评估个人外照射剂量,并评估了与个人外照射剂量相关的参数,如建筑物和车辆造成的辐射减少效应。利用在福岛第一核电站(FDNPS)事故影响地区测量到的环境辐射数据集,对模型参数进行了评估。模型估算的有效剂量与福岛第一核电站附近居民生活环境中使用个人剂量计测量的 106 个日个人剂量当量进行了比较。估算的有效剂量与测得的个人剂量当量相当,特别是在室内剂量估算中考虑自然辐射时。该模型足以用于辐射防护,利用环境辐射监测数据对个人外照射剂量进行预测和回顾性估算。

Assessment of individual external exposure doses based on environmental radiation in areas affected by the Fukushima Daiichi Nuclear Power Station accident
Assessing individual external exposure doses from ambient dose equivalents is valuable for predictive and retrospective purposes when personal dosimeters are impractical. This study developed a model to assess individual external exposure doses from ambient dose equivalents, considering daily life patterns (location and time spent in various places), and evaluated parameters associated with individual external exposure doses, such as the reduction effects of radiation due to buildings and vehicles. The model parameters were evaluated using the robust datasets of environmental radiation measured in areas affected by the Fukushima Daiichi Nuclear Power Station (FDNPS) accident. The effective dose estimated by the model was compared to 106 daily personal dose equivalents measured using personal dosimeters in the residents’ living environments near the FDNPS. The estimated effective dose well consists with the measured personal dose equivalents, particularly when considering natural radiation in indoor dose estimation. This model is adequate for radiation protection, enabling the predictive and retrospective estimation of individual external exposure doses using environmental radiation monitoring data.

期刊介绍: Environmental Health publishes manuscripts focusing on critical aspects of environmental and occupational medicine, including studies in toxicology and epidemiology, to illuminate the human health implications of exposure to environmental hazards. The journal adopts an open-access model and practices open peer review. It caters to scientists and practitioners across all environmental science domains, directly or indirectly impacting human health and well-being. With a commitment to enhancing the prevention of environmentally-related health risks, Environmental Health serves as a public health journal for the community and scientists engaged in matters of public health significance concerning the environment.
