I'd like to suggest a very nasty encounter type, for more harshness, RadAway and RadX marketing and more SP spent in Outdoor.
So: Bomb crater (most probably), nuclear waste, reactor debris. Anything gets a player (slightly) irradiated. And some victims with humble loot, perhaps.
This is a postnuclear wasteland isn't it?
Radiation should be a survival problem, it's the land that is irradiated, not only critters and not only around Glow.
Next time you start farming in a abandoned city or travel across the area around Glow, it might be a good idea to pop some Rad-X.
