Exposures to Radiation

Iodine-131 was carried by winds to surrounding areas and deposited on vegetation. It was then absorbed in the milk of cows and goats that grazed on the contaminated vegetation. Drinking contaminated milk caused most of the radiation dose for most of the exposed people.

People were also exposed by eating contaminated fruits and vegetables, and by breathing contaminated air.
