The Russian forces there didn't have dosimeters. And the Red Forest is really where the stuff was falling right out of the reactor. I think even just undisturbed background level there is about several milli-R/hr. So, in a month you'd get several Roentgen. From some sources - the levels once disturbed would shoot to the scale of 100-200 milli-R/hr. That is 100-200 R/month. Those level do produce ARS with some deaths.
