I am speaking of going back to background levels. In my life I have had about 3 dozen CT scans and 100s of regyualr x-rays but I am still healthy.

There are three main types of radiation you need to worry about in a nuclear accident, alpha and beta radiation can be stopped by almost any solid material and the risk here is from breathing in radioactive dust. The next is gamma and the majority of this disappears in 100 days.

3 dozen CT scans and 100s of x-rays?

What line of work are you in or, if not due to work, that’s a lot of CT scans. ???
