I used to experience mutant hound chops removing 50 rads but now they remove only 5 rads.
Stat description when highlighting in pip boy used to say 50 , now its 5.
When cooking , the recipe does say 50 in the text FOOD DESCRIPTION

Not confirmed if its purely a stat description issue as I switched between survival and non survival mode before and when I tested, it seemed like only 5 rads were removed.
