1. Recently in Beijing and Tianjin in the open-air cultivation of spinach iodine-131 was detected, depending on what is? Have no effect on public health?
health sector, April 5 from Beijing, Tianjin and Henan region in the open-air cultivation of spinach sampling found traces of radioactive iodine-131, content 1-3Bq/kg, respectively. Due to an iodine-131 out of trace, on public health no effects of the present situation.
2. Why choose spinach for testing?
past monitoring experience showed that radioactive pollution in vegetables in a nuclear accident: open big leaf growth, slightly down on the surface of vegetables easy settlement of radioactive substances in the air. Therefore, select the detection can be found earlier in spinach vegetables contaminated by radioactive substances. Practice has proven that wash with water can effectively reduce radioactive substances on the surface of vegetables.
3. Check out iodine-131 in the spinach in the open after rainfall occurs, do what is the relationship between the two?
of radioactive substances in the air on a final settlement to the ground. Concentration of radioactive substances in the air due to the country at very low levels, its settlement caused radioactive pollution of vegetables in General difficult to check out. Beijing and Tianjin area rain in recent days, rainfall accelerated the settlement of radioactive substances in the air, and rain making the surface of these materials can be kept in the spinach is not washed away, so detected in spinach samples of iodine-131.
4. Food results in detection of radionuclides and there is no correlation between test results of air?
settlement of radioactive substances in the air pollution of ground and surface growth of vegetables and other foods. Higher concentrations of radioactive substances in the air, growth of settlement to the ground and open more radioactive substances on the surface of vegetables. Rain and snow weather can speed up settlement of radioactive substances in the air.
5. Now working on food and drinking water testing is carried out on how to deploy?
2011, March 11 Japan Fukushima nuclear power plant after the accident, rapid deployment of the Northeast and the Ministry of health related agencies prepare the food and drinking water monitoring work in coastal areas, China CDC completed training technology and technical training for staff of the organizations concerned. 26th national nuclear Emergency Coordination Committee announced after iodine-131 was detected in the air, the Ministry of health commissioned the Chinese Center for disease control and prevention now in Liaoning, Hebei, Jiangsu, Zhejiang, Beijing, Shanghai, Guangdong, Shandong and other 14 provinces and to carry out a radioactive food and drinking water monitoring.
6. With the gradual increase rainfall throughout, radionuclide contamination in food and water will become more and more serious? What preventive measures can be taken to the public?
depending on the concentration of radioactive substances in the air. Concentration of radioactive substances in the air depends on Japan Fukushima nuclear power plants release radioactive material amount and duration, and the meteorological conditions (such as wind direction, wind speed and atmospheric circulation, and so on). Rain duration and rainfall was directly affected vegetable pollution levels of the radioactive material. Current trace of radionuclides in food surveillance, does not affect the public's health, do not need to take protective measures. Public concern over the Government Authority published to gauge progress.
