Radiation When You Fly

Whole-body scanning at airports has become more popular over the past few years. Some are concerned that the radiation from these scans can be a health risk. One type of scanner does not expose people to radiation. But the other type does expose people to a small amount. Experts point out that millions of people will undergo whole-body scanning. But there are many other sources of radiation that people are exposed to each day. Experts also recommend that airports choose scanners with millimeter wave technology, which does not expose people to radiation. The articles appear in the April issue of the journal Radiology.
