21. Type of food affects a level of contamination in the body

The primary cause of internal exposure is ingestion of contaminated food, not inhalation of contaminated air.

To avoid taking in contaminated food, "the place of production" is not important. Various inspections have confirmed that the "type of food" influences the level of contamination. Indeed, specific "types of food" such as mushrooms, some wild vegetables, and meat, could be associated with contamination which would exceed the standard value, although its frequency is on the decrease year by year.

On the other hand, rice and vegetables are safe most of the time and “the place of production" regardless of whether they were made in Fukushima or grown in the home garden, does not affect the level of radiation exposure.
