Amazing report. You certainly have a lot of courage and ability to visit this area. The climb to the top of the Duga Array must rank as one of the greatest ever achiements on 28dayslater..
Interesting to read on other websites about how many wild animals are living in the area, and seem to survive the radiation.
This was the thing that worried me the most before we went and I ended up ordering a Seychelle radiological filter and double filtering drinking water with some Ukrainian filters as well. This worked fine until the last 24 hours when all the filters had completely frozen and nothing was doing its job properly. There was a water cache in the town but that had completely frozen too so by that point it really was time to leave!
