Figure 2

Temporal changes in 137Cs activity concentrations in wild boar muscle samples collected inside the difficult-to-return zone (DRZ) and three regions outside the DRZ (Hamadori, Nakadori and Aizu). The map shows each region using different colors. The DRZ (10 March in 2020) on the map includes the specific reconstruction areas in which restrictions on entry have been lifted. The simple linear regression equation (each line) and the 95% confidence interval about the regression line (grey shaded area) are shown in the figure. The original map was created using ArcGIS Pro 3.1.6 (https://www.esri.com/en-us/arcgis/products/arcgis-pro/overview). The map of Fukushima Prefecture was obtained from the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) of Japan (http://nlftp.mlit.go.jp/ksj/) and area of difficult to return zone (DRZ) was created based on conceptual diagram of evacuation area on March 10 in 2020 (https://www.pref.fukushima.lg.jp/site/portal/cat01-more.html).
