Medical facilities really do try to minimize exposure to radiation of
parts of the body not needing treatment, especially the gonads.
Indeed, if the whole body were seriously irradiated (such as in a
nuclear accident at a power plant), the person would become very
obviously sick because of the damaged and dying cells. People living
through such accidents would certainly suffer some genetic damage, but
it's not clear whether radiation has any effect on replication
slippage (the type of mutation we see in genealogical Y DNA testing).
