How much do you know about the radiation dose around you?

According to the China Center for Disease Control, a small amount of radiation exposure will not endanger human health. Excessive exposure to radioactive rays can cause harm to humans, causing human illness and death. The greater the dose, the greater the hazard.

The data shows that human beings live in all kinds of radiation at all times. The global average annual effective dose of individuals from natural radiation is about 2.4 mSv, of which 0.4 mSv from cosmic rays and 0.5 mSv from terrestrial gamma rays. Inhalation (mainly indoor radon) produces 1.2 mSv, ingestion is 0.3 mSv.

The radiation dose of air, food and water that people ingest every year is about 0.25 mSv. Dai Luminometer has 0.02 millisieverts per year; travels 2000 kilometers by plane, about 0.01 millisieverts; smokes 20 cigarettes a day, 0.5-1 millisieverts a year; one X-ray examination 0.1 millisieverts.

The data shows that when the radiation dose is less than 100 mSv, there is no medically deterministic effect on the human body, that is, obvious tissue damage; when the dose exceeds 4000 mSv, there is 50% without medical monitoring % Mortality, and when the dose exceeds 6000 mSv, it can be fatal.
