Help

i think it lasts for a month or so. to my knowledge, it affects your income as far as pulling resources from the affected squares. i don't think it damages units that pass through the area, but i'm not certain.

I do know that Johnny avoided irradiated property, not taking it until it was clear.

Yes, moving through radiation will damage units.

It'll last a few weeks, but it'll vary depending on how much strength the bomb had when it hit.
