In April 2020, several wildfires took place in and around the Chernobyl exclusion zone. These fires reintroduced radioactive particles deposited during the 1986 Chernobyl disaster into the atmosphere, causing concern about a possible radiation hazard. Several countries and several stations of the International Monitoring System measured increased Cs137 levels. This study presents the analyses made by RIVM and SCK CEN/RMI during the April 2020 wildfires. Furthermore, more in-depth research was performed after the wildfires. A statistical analysis of Cs137 detections is presented, comparing the April 2020 detections with historical detections. Inverse atmospheric transport modelling is applied to infer the total released Cs137 during the wildfires. Finally, it is assessed whether the Cs137 detections in Belgium and the Netherlands can be attributed to the wildfires.
2020 年 4 月，切尔诺贝利隔离区内外发生了几起野火。这些火灾将 1986 年切尔诺贝利灾难期间沉积的放射性粒子重新释放到大气中，引发了对可能存在辐射危害的担忧。几个国家和国际监测系统的几个站点测量到铯 137 水平升高。本研究介绍了 RIVM 和 SCK CEN/RMI 在 2020 年 4 月野火期间进行的分析。此外，野火后还进行了更深入的研究。对铯 137 的检测进行了统计分析，将 2020 年 4 月的检测结果与历史检测结果进行了比较。应用反向大气输送模型推断火灾期间释放的总铯 137。最后，评估了比利时和荷兰的铯 137 检测是否归因于野火。
