The mean annual effective dose for Finnish people

The mean annual effective dose for Finnish people

The mean effective annual dose for a Finn is 3.2 millisievert. Half of the dose is attributable to indoor radon exposure and roughly one third of the annual effective dose is caused by natural
background radiation. Ca. fifteen per cent of the dose comes from medical use of radiation.

The mean annual dose from the Chernobyl fallout is less than one percent of the total annual dose for a Finn. The effective dose to Finnish population from the Fukushima Dai-ichi nuclear power plant accident that occurred in Japan in 2011 is negligible.
