Answer to Question #1499 Submitted to "Ask the Experts"

Category: Pregnancy and Radiation — Power lines, magnets, computers, airport screening, cell phones

The following question was answered by an expert in the appropriate field:

My wife is pregnant and we are traveling for the holidays. I saw your answer to the pregnant woman about her concerns about the security radiation. You say it is harmless. My questions: What kind of radiation is it? How do those walk-through devices work?

There are two screening devices at the airport. One is an x ray machine that looks at your luggage. That machine is well shielded and exposes no one to any significant exposure to x rays—neither the workers or the passengers. The other apparatus is a metal-detecting device that is nonionizing electromagnetic "radiation." That exposure has no reproductive effects that should concern your wife. There are no measurable effects from this exposure to the embryo. Of course I cannot remove the background risk of 15% miscarriage and 3% birth defects that all normal pregnant women face. Robert L. Brent, MD, PhD
