What to do about radiation from x rays and unborn babies?

Xrays in pregnancy: First, try to avoid radiation. If it is so important someone's health is at great risk, go ahead with the x-ray but try to avoid exposure of the uterus by covering it with lead apron. Really try to avoid big time radiation like CT scans. If the x-ray has already taken place before you knew you were pregnant, not much to do now except inform your OB so they are aware the exposure took place.
