What do people need to do to avoid the risk of radiation exposure?

Japan has warned people living in a 30km radius around the Fukushima nuclear power plant area to stay indoors to avoid the risk of being exposed to radiation after three explosions at No.1, 2 and 3 of this factory.

There were 190 Japanese people at risk of radiation exposure

Japanese media reported that 190 people have been tested and are likely to be exposed to radioactive material after the earthquake. However, the level of contamination is considered mild, so the Japanese Government has not yet declared a state of emergency for pollution.

Japanese Prime Minister Naoto Kan warned that: 'The risk of radioactive contamination leaking from Fukushima nuclear power is very high. Currently, we are analyzing the level of danger of radioactivity in this area to people's health. Initial test results show that radiation has appeared in areas near this plant . '

Hong Kong's Dai Cong Gazette on March 14, 2011 introduced from the website of the US Emergency Management Agency (FEMA) on how to prevent nuclear radiation as follows:

- At any time, you must also bring a battery-operated radio to listen to specific instructions; close and lock the doors in the house; Put the food in a sealed container or in the refrigerator and for unsealed foods to be washed and put in a sealed container or in the refrigerator.

- If evacuation is required, you should still pay attention to closing windows and ventilation windows; use air recirculation system.

- If there is a suggestion to stay indoors, you must turn off the air conditioner, ventilation fan, boiler and other air-intake devices, in case it is not really necessary to use the phone and, if possible, stay hide in places below ground.

- If you surmise that you have been exposed to radiation, change your clothes and shoes, let the things you wear are exposed to radiation into a plastic bag, seal it and leave it in a hidden place, then wash yourself thoroughly. clean.

Radiation from nuclear reactor explosions can adversely affect health

However, people in Tokyo capital should not be too worried because the Institute of Energy Safety, Japanese Nuclear (NISA) said that the radioactivity measured in Tokyo is very small and likely to affect to health is not available.

Judging by the level of health effects with a radioactive concentration of 100 millisievert to 400 millisievert for human health, the Asahi Shimbun news network leads nuclear medical data to indicate that normally a person is exposed to radiation as much as so there are different changes.

If less than 100 milisievert, radiation does not affect the fetus while at 400 millisievert as in Fukushima No.1 Power Plant, people will experience acute radiation shock as the immune system will decline rapidly, external bleeding skin, intestinal mucosa and blood count in the blood drastically reduced.

Symptoms of radiation infection: Nausea, fever .

Nuclear disasters in Japan at any time can cause harm to surrounding countries and regions. Radiation leakage can seriously affect human health.

According to experts, people who come into contact with an average amount of radioactivity will lead to early symptoms such as nausea and fatigue accompanied by erythema, possibly fever with diarrhea and other unresolved symptoms. like the cause.

Next is an incubation period with different time (2-4 weeks), symptoms of infection, bleeding, gastrointestinal disease, lack of blood cells, skin lesions, symptoms Epilation or problems (such as blood spots, bleeding from the teeth or nose) and victims can die later.

Inhalation or ingestion of radioactive contaminated food can cause thyroid cancer. The thyroid gland is a large gland in the front of the neck, producing hormones that control body growth.

Food is also contaminated with radiation when radioactive dust falls on crops, fruits and even grass that cattle and buffalo eat. Water and water in the plumbing is also contaminated with radiation.

In the long run, survivors of radiation contamination, depending on the dose and duration of exposure to radioactive substances, may be affected by various diseases such as blood cancer, lung cancer, thyroid cancer, Breast cancer and other types of organ cancer.

Radiation poisoning not only causes cancer of organs but also mutates cells in the body and is inherited for children , leading to malformations, abnormal growth of the body in the future generation. hybrids such as: small heads, disgruntled brain size often lead to poor intelligence, poor eyes or blindness, slow body development and learning difficulties
