I was also wondering this - if you have a chest x ray, which, according to the link you gave to another persons query, is the equivalent of 10 days worth of radiation - is it more harmful to have this 10 days worth all at once, as opposed to spread out over 10 days? As for example, sun exposure at a large dose at once can cause burning, but the same amount spread out over days is not harmful? Also is the equivalent for a childs chest x ray less than this? Many thanks again, this site is very interesting and informative. Hi Doctor
