The natural radiation dose in daily life is 2-4 millisieverts.
Once less than 100 millisieverts of radiation, there is no change in clinical observation, which is considered to have no effect on the human body.
A 1000-2000 millisievert may cause mild acute radiation sickness and can be cured.
The radiation level at the front gate of the fukushima plant was 8.217 millisieverts per hour, or about eight times the maximum annual allowable limit.
In our daily life, we take a 10-hour plane, equivalent to 0.03 MSV radiation.
A pack of cigarettes a day and a dose of 0.5~1 millisievert a year.
The maximum annual dose for professionals is 20 millisieverts.
A one-time 4,000 millisieverts could kill.
Groups of people were ordered by radiation
Fetus: cell division is the fastest, the more obvious the effects of radiation;
Children: children who are exposed to radiation are 3-5 times more likely to have thyroid cancer years later than the average child.
Adolescents: normal thyroid function and active metabolism;
Old man: the thyroid function is relatively young and inactive, and the metabolism is slow
List of radiation protection measures
If exposed to radiation, immediately change a set of clothes and shoes, place them in a sealed plastic bag, seal the pocket, and take a thorough shower.
If you are told to evacuate, keep Windows and vents enclosed in the car, and circulate air in the car;
If you are told to stay indoors, turn off the air conditioning and other air intake, go to a basement, and avoid using the phone unless absolutely necessary.
Potassium iodide can help reduce the risk of cancer before or after exposure to radiation. But it must be under the guidance of a doctor
If daily life wants to improve the radiation protection ability, can eat the food with high iodine content such as kelp, seaweed, also can drink red wine, improve the body antioxidant capacity
Always listen to specific instructions on a battery radio.
A comprehensive plan for radiation prevention
Approach 1: contaminate food and water
Seriousness: one of the most important ways
Prevention: avoid contaminated seafood. Don't drink seawater desalinated. Eat more seaweed and other foods that contain iodine, but don't take iodine pills, only when the government is issuing iodine pills!
Pathway 2: inhalation of polluted air
Seriousness: one of the most important ways
Prevention: people in the polluted area should avoid going out and closing doors and Windows. If you must go out, try to avoid a long stay, cover your mouth and nose with a wet towel, or wear a mask.
Pathway 3: dust absorbed and deposited by the skin
Severity: a more important approach
Prevention plan: minimize exposed areas, wear radiation protective clothing, neck (thyroid) parts especially important. Wash with soap every day. Avoid get wet in the rain
Pathway 4: dust absorbed and deposited by the skin
Exposure: food intake, inhalation, puncture, wound, skin contamination.
Harmful organs: bone table
Risk: exposure to radiation exposure can significantly increase the risk of cancer and organ damage.
Studies have shown that radiation exposure is associated with the body's oxidation. Therefore, to guard against nuclear radiation, besides avoiding the "close contact" with radiation and wearing radiation protective clothing, certain nutrition counteracting radiation has a very important role. In nuclear sites, nuclear arsenals, nuclear submarines, nuclear explosions, and so on, people can resist or reduce the damage caused by nuclear radiation through diet methods, which has been confirmed by the institute of modern medicine.
