I have 3 problems with Rad Storms: 1: There is no indication of what to do when we encounter one. There are no cues from NPC behaviour, nor any tutorial section about them. Remember, you're a Vault Dweller so you have no idea what one is, maybe your Companions could clue you in... 2: As mentioned above, the methods for avoiding them are equally immersion-breaking. Sitting, sleeping and fast travel make as little sense as simply shutting the doors and windows. 3: It begs the question of why anyone even bothers living above ground. Living in a house would be suicidal. Speaking of which, it would be kinda cool if Ghouls, Glowing mobs and Super Mutants had a higher spawn rate and were buffed inside a Rad Storm.
