Most of the color radiation maps that I have are from the Bulletin of the Ecological State of the Exclusion Zone, an excellent journal published by the Ukrainian Ministry of Emergencies. Unfortunately, all the maps have creases down the center and few are translated into English. I will add better maps if I can find some.
The color scale on the left represent kilo-becquerel per square meter. Before I knew that I'd be needing the map for this website, I drew the black circles to define the borders of the Przewalski's horses' ranges for Chapter 5. The solid line represents Vypad's herd's range and the dotted line is Volny's.
