The danger, as revealed by research studies, is for female breast cancer :) Since most of the radiation absorbed by OR personnel comes from the patient in the form of scatter radiation, it is very important i.e. the table height; hence the patient, is much closer to breast height than male anatomical appendages!:kiss Seriously, any female working around image guided procedures is at increased risk for breast cancer due to occupational exposure and should bear the slight extra weight to protect her breast tissue. It is common knowledge that breast tissue is radiosensitive.
