I don't know much about the current safety measures for working around fluoroscopy, but, couldn't you just wear a "gonad apron" as we used to call them, (which actually, was much like an ordinary 'cooking' apron, covering entire abdomen, except hugely heavy). Seems like a good idea to do this even while just trying to conceive, in the event you are only a day or so pregnant.
also, slightly off topic, but, i always insisted i get a "thyroid" cover, as well, and was always stunned so few others did that. For real, i'd often be only one in the room wearing one, and the thyroid is so sensitive to radiation.. BUT This was a while ago, though, perhaps nowadays those thyroid covers are more commonly used by all.
but, hopefully, someone who knows just what safety measures are needed, will be by. You also might consider posting this question in one of the Specialty
Pain therapy nurses:
(the OR nurses might know a thing or two about proper safety radiation measures during pregnancy, too)
