I know this isn't a big concern because I would assume there would be enough regulations to keep the hospitals safe but have there been any concerns about RadOncs and exposure to radiation, esp. pregnant RadOncs? thanks.
It's really not an issue. For external beam procedures (the majority of treatments), the radiation oncologist is not in the vault with the patient. And since treatment machines are installed in lead-fortified vaults, there is no danger to anyone else in the vicinity. I know plenty of (past and current) pregnant radiation oncologists, both at the attending and resident level. I would try to avoid brachytherapy during pregnancy, but even these procedures are done with appropriate shielding (of course). How would we prepare for the future of our specialty if we couldn't procreate and spawn baby radiation oncologists-to-be?
