jonb- speaking as a radiographer I would hope that only the essential bits, that are of interest, would be irradiated, we do not just go chucking radiation about for the fun of it. It is not always bad for you, there is a risk associated but it is often outweighed by the benefits, think of radiotherapy for instance. There is also a theory, hormesis, that in low doses radiation can actually be of benefit to you.
WCA- as a radiographer working in Southampton, you were either very lucky, or have a low threshhold!
Miketually- if you are on the mend, I’d give it a miss. You won’t get a chance to see your insides, If you are really concerned it will put your mind at rest but not for a while, until the results are ready, which might be a couple of weeks.
