The following websites have questions answered by qualified medical personnel who are experts in radiation and the effects of radiation. Here is what I found:
“Medical x rays are highly collimated, that is, the beam is directed to only the part of the body being examined. Thus very little, if any, radiation reached the abdomen during your chest x rays. No effects of radiation exposure are likely.”http://hps.org/publicinformation/ate/q73…
“X rays of the chest result in minimal, if any, exposure to the unborn child because the x-ray beam is directed only at the chest region. Little, if any, radiation exposes the abdominal area. Health risks to the unborn child because of x-ray exposure in your case should not be a cause of alarm or concern.”http://hps.org/publicinformation/ate/q56…
“When you receive a chest x ray at a qualified facility, the exposure of the x rays is to your chest, not to your embryo. The “scatter” that might reach the embryo would be extremely small and would not represent an increased risk for birth defects or miscarriage to your embryo. If you are healthy and young and have no reproductive problems or family history of reproductive problems your risk for birth defects is 3% and for miscarriage, 15%. Neither you nor I can change that risk.”http://hps.org/publicinformation/ate/q13…
