Radiation is not dangerous to the human body if it is low dose. However, as in the case of Chernobyl and Hiroshima Nagasaki A-bombs, when exposed to sharply higher doses than a certain dose, the risk of carcinogenesis will be higher than those who do not. However, compared to radiation below a certain dose, smoking, excessive drinking, etc., is much more risky in carcinogenesis, so we should try to improve our lifestyle rather than break down radiation.
