They do it all day everyday. That would be bad over the years. Plus any unnecessary exposure to any additional radiation should just be avoided. If the patient had any other way of getting the same results im sure that would be the preferred method but its all we got and 1 dose is really nothing in the scheme of things.
I do remember a story long ago in the early days where someone got a faulty one and everytime they turned it on for xrays these people were hit with so much radiation they could taste it. Nobody believed them and it was so bad that side effects came quick enough to figure out this machine was faulty. If i find it ill link it here. Very interesting and awful situation.
Edit: found it the Therac-25 system. It sometimes became faulty and dosed people with 250 times the amount it should have. They swore up and down there is no way the system was faulty until it was finally proven to be it.
