Radioactivity in food and environment


  • Radioactive substances are found everywhere in nature, including our bodies.

  • Most of the radiation we are exposed to is from naturally occurring radioactive substances.

  • In Norway, the Chernobyl accident in 1986 is the largest source of radioactive contamination. Radioactive caesium from the accident is still present in the Norwegian environment.

  • The health risks associated with radioactivity in the environment and food are low for most people.
