"Gamma ray dose rate maps of Fukushima Prefecture These maps were modified by using PowerPoint® and Adobe Reader® software, from maps obtained by airborne monitoring surveys made in April to June, 2012.

Original context as given in the source mentioned above: "Figures 3 and 4 (a) show that the gamma ray dose rate was the highest in the Soso area followed by the Kempoku and the Kenchu area. Most of the Soso area was designated as the Evacuation Area or Deliberate Evacuation Area. Many of the Soso residents evacuated from their original location, which is a possible reason for their average dose being lower than the average doses for residents of the Kempoku and Kenchu areas. The average doses for Aizu (0.2 mSv) and Minami-Aizu (0.1 mSv) areas were smaller than those for other areas due to their greater distance from the Fukushima Dai-ichi NPP. A blown-up map of the area with the highest gamma ray dose rate is shown in Fig. 4(b)15. Table 2 lists

the dose distribution for each of the six municipalities shown in Fig. 4(b). A more detailed dose distribution is shown in Table S1 in the Supplementary Information. As shown in Table S1, most of the higher doses were reported in Iitate Village and Namie Town. Figure 4(b) indicates that the gamma ray dose rate was generally higher in Namie Town, with similar individual doses seen in Iitate Village (Table S1)."
