The current level in the Red Forest is 0.1-10mSv/h. So in a month one would get 0.07-7Sv - already a death/live lottery depending on where one was located during that month that the Russian soldiers spent there. Yet the real kicker is that Russian army drove armor and dug trenches in the Red Forest. Disturbing soil there immediately makes a hot spot with many times increased level. And moving armor and digging raised the dust which means the soldiers got breathed a lot of that stuff in which is much worse for the health than even that increased background level. So, yes, low hundreds (judging by the number of soldiers brought just to that Belarussian hospital) of Darwin awards are due here.
Russian presence there was documented by multiple sources - i at the time saw much from Telegram, Ukrainian and oppositional Russian sources - and here for example is more typical Western source:

I saw many times people just doubt that story without any specific reason, and i'm yet to hear what specifically they doubt - the radiation levels? Russian presence? or may be the arithmetic of the levels multiplied by the length of the presence?
Your own link downplays the radiation level to "basically harmless" and attributes the problems to a psychosomatic response.
Which I personally would doubt. Such a determination could only be made by on-site measurements. By now, radiation should be highly localized in certain areas and soil formations through rain wash-off and intentional burying of contaminated surfaces. So while a lot of places might be harmless, there should be some that are definitely not.
Whats more, the red forest due to proximity and wind conditions, got the major part of the heavier isotopes. The combination of those can be extra-nasty due to their gamma energy, bioavailability and half-life when compared to the lighter stuff that spread out over Europe.
