Ionizing
Radiation Facts
• 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.
