Effects of Radiation on the Body

Is it abnormal if radiation is detected from foods?

Foods have always contained natural radioactive substances.

Soils contain natural radioactive substances such as potassium. Consequently, all sorts of foods contain radioactive substances present in the natural world. Our bodies, which ingest radioactive substances in our food on a daily basis, have a radioactivity level of about 7,000 becquerels (given a 60 kg male).
