Every time I start the game my rads level increases by 1-3 points without stopping despite not having been to places with high levels of radiation from my previous save.

I tried whatever I could to stop the problem (Rads Away/Resist, cure rads) but the rads just kept increasing for no reason. As far as I'm aware, the only way to stop it from increasing is fast-travelling from my current location to another.

I can't tell if this is normal (part of the game as intended) or just one of the game's technical issue, but it's getting extremely annoying.

Is anyone else experiencing this as well?

Thanks.
