In 2022 the German Federal Office for Radiation Protection (BfS) in cooperation with State Agency of Ukraine on Exclusion Zone Management has published the initial results of the radiological remapping of the exclusion zone. The data can be used to assess which areas of the exclusion zone could be reopened for use. The start of Russian invasion halted all this activities and research.
