I dunno where you get the information but I know for a fact that 10 miles from the actual reactor the radiation levels are just the same as downtown Kiev, or London for that matter, and much lower than for instance in my home town due to natural earth radiation being rather high here...actually about 5 times that in Chernobyl, within the closed zone.

Shows the radiation is 30x the average world background levels at the very sargophagus...which is still less than in my home, and wayyy less you than what you get in a normal X-ray operation.
