I am an OR circulator, and I am trying to get pregnant. I also circulate in many radiation cases. Once a staff member becomes pregnant at my facility we try to have other staff circulate the radiation cases, especially in the first trimester. If this is not possible, it is okay to wear lead but you must get a fetus badge to wear at your waist when you are in these cases. I believe you should let your manager know so that you can take these extra precautions. Congratulations!!!
