Iodine-13 1 is an artificial radionuclide (nuclear fission product), which does not exist in nature under normal circumstances. This radionuclide is contained in the radionuclides released from the nuclear accident in Japan. At present, iodine-13 1 has been detected in the air in the northeast of Heilongjiang, which only shows that radioactive materials leaked from Japan have reached China with the atmospheric diffusion, but the concentration is extremely weak and will not cause harm to public health in China.
2. Iodine-13 1 will cause harm to people. What is the current monitoring amount?
According to the information released by the National Nuclear Accident Emergency Coordination Committee on March 26th, a very small amount of artificial radionuclide iodine-13 1 was found in the air in the northeast of Heilongjiang Province, China, and its dose to the local public was less than one hundred thousand of the natural background radiation dose. On this basis, it is estimated that the public will continue to take it for one year, and the resulting dose is about one hundred thousandth of the annual dose limit (1-2002) stipulated by the national standard (GB 1887 1-2002), which will not affect public health. Considering that the current concentration environment will not last for one year, the concentration will soon decrease, and the actual result will be much lower than the above value.
3. What health effects will iodine-13 1 have on human body? Will it pollute food and water and endanger our health?
After iodine-13 1 is ingested into human body, it mainly accumulates in thyroid gland, which is harmful to human body. Large doses will lead to goiter, thyroid nodules or atrophy, and the incidence of thyroid cancer will increase due to the influence of far and late stage.
Judging from the current monitoring results, only a very small amount of radionuclides have been detected, which will not pollute our food and drinking water and will not affect our public health.
4. How to get relevant information in time, and what should be paid attention to in the current situation? What protection can individuals do when the situation is serious? Is there an effective treatment?
Relevant state departments have monitored the impact of Japanese nuclear leakage on China in real time, and will release relevant information in time. The public should pay close attention to the authoritative information released by the relevant state departments in a timely manner. Under the current circumstances, it will not cause harm to public health and there is no need to take protective measures. According to the requirements of the Ministry of Health, the provincial health administrative departments designate medical and health institutions in their respective jurisdictions to carry out personnel radiation pollution detection, medical treatment and radiation injury treatment.
5. Did the health department monitor the radiation pollution of food and drinking water in relevant places, and what was the result?
Since the nuclear accident in Japan, the health department has been paying close attention to the development of the situation, and timely deployed 14 provinces and cities in Beijing, Northeast China and coastal areas to carry out radioactive monitoring of food and drinking water.
