We are constantly exposed to radiation from natural sources in our daily lives, such as the radiation that comes from outer space and the earth, as well as the radiation emitted by natural radioactive substances contained within airborne dust and food. The average for this on a worldwide scale is approximately 2.4 millisieverts per year.
We are also exposed to radioactivity during medical procedures, such as X-rays and stomach examinations. To differentiate it from natural radiation, this type of radiation is called “artificial radiation”.
The amount of artificial radiation that we are exposed to in the vicinity of nuclear power plants is strictly controlled to not exceed the annual targeted value of 0.05 millisieverts.
It has been confirmed that the amount of radiation in the vicinity of nuclear power plants is actually much lower than the annual targeted value, standing at 0.001 millisieverts or less.
