Answer to Question #7263 Submitted to "Ask the Experts"

Category: Medical and Dental Patient Issues — Diagnostic X Ray and CT

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

My son was born having swallowed heavy meconium. He was not getting any oxygen in his lungs and was in intensive care for two weeks. During this time, they x rayed his lungs possibly four or five times. What effects will it have on him? What signs should I be looking for if this has affected him in any way?


The radiation dose from chest x rays is the lowest of any x-ray procedure and is equal to about two or three weeks of background radiation. Even five of them produce an extremely low dose, that is, so small as to be a nonissue. It will have no effects on your baby.
