I have a couple of dwellers with maxed out stats by now. When they go out to level up, they will not take red radiation damage for several days. The maximum I have so far managed was around five days without needing a radaway.
However, when I send the same dwellers out the second time when they are already 50, they get radiation damage. It's slow and not enough for them to use a radaway on two days, but there is red damage.
I assumed with Endurance on 10 that would not happen at all. Why are they not immune to radiation?
