Radiation and Pregnancy

Radiation comes in many forms. Ionizing radiation emitted from x-rays can be worrisome to many pregnant women, and rightfully so. It is dangerous for the developing fetus to be exposed to high levels of ionizing radiation. Steps should be taken to avoid or reduce the danger during pregnancy since it is something we can voluntarily prevent. Radiation exposure to the fetus can result in miscarriage and severe birth defects.

• Mostly, ionizing radiation can be a problem only when you are exposed to large doses or small, regular doses over a length of time.
• According to experts, no single diagnostic x-ray procedure can cause harm to the pregnant woman or her fetus. Nevertheless it is advisable to avoid unnecessary exposure during pregnancy. Always inform any doctor (a GP for instance) and dentist of your pregnancy whenever you have an appointment for any reason.
• Avoid mammograms or dental works requiring x-rays during pregnancy. These procedures can wait till after the baby is delivered
• Risk from radiation exposure is highest in the first trimester
• Postpone any elective medical procedures until after having your baby. For instance dental care which usually requires x-rays can be delayed to a later date
• If x-rays are an absolute necessity e.g. a fracture, explain your pregnancy to the radiologist so that proper measures to reduce the degree of radiation will be taken; insist on minimal dose of radiation and the lowest number of x-rays possible. Take note that a lead apron to protect all other areas (especially the abdomen) of your body is always given, and request for one if not.
• Women holding jobs which exposes them to high levels of radiation should switch jobs or shift to one where the exposure is minimal
• Flying exposes the pregnant woman to small amounts of radiation but the risk is very minimal. The theory behind this is that when you are 30,000 feet up in the air the radiation gets to you more since the atmosphere level drops considerably. Miscarriage risk increases if you fly more than 75,000 miles per month during your pregnancy.
• Airport security radiation only applies to your baggage. Passengers currently go through metal detectors which do not discharge any ionizing radiation.
