Q. How are people exposed to radiation?
A. Radioactive particles in fallout can be inhaled into the lungs, fall on the skin or be ingested through contaminated food or water. The level can vary greatly even between short distances, said Dr. Fred Mettler, a University of New Mexico radiologist who led an international study of health effects after the 1986 Chernobyl disaster.
"You can come around a corner and the dose rate can be very high, and you get back behind a column and the dose rate is much lower," depending on what type of particles are in the fallout, whether you're standing under a roof where they've accumulated or shielded you from them, etc, he said.
