Leaked radioactive materials in the air may come down and remain deposited on the earth surfaces, buildings, and other places.In this case, radioactive materials may be taken inside of our body by ingesting contaminated water and agricultural products.
Moreover, protect your mouth and nose when you go out as you could directly inhale the radioactive materials in the air.
Radiation exposure may affect your health, but the influence and the type depend on the exposure level.For example below 100 milli Sievert (m Sv) (100,000 micro Sv (μSv)),there is no immediate health effect.It is thought that the probability of getting cancer may increase with radiation doses,and this happens only in the period between several years and several decades after the exposure.For example, the risk of getting cancer is about 0.5% in the case of 100 milli Sv (mSv) radiation exposure.This value is significantly lower than the risk of cancer caused by factors such as smoking and food.Thus, there is no need for undue concern.
