Beijing-Tianjin spinach detection radiates things: Relate to rainfall There is precipitation in the North
According to the news of Chinese Ministry of Public Health website, the food relevant knowledge question and answer of radioactive pollution of today of Ministry of Public Health. Mention while answering a question, inspect in the spinach which the Ministry of Health plants from Beijing, Tianjin and Henan area in the open on April 5 by random samples and find micro- radioactive iodine - 131, the content is 1-3Bq/kg respectively. Because of iodine of detection - 131 traces, the situation has not influenced public health at present. The faithful record of question and answer is as follows: 1. Detect iodine - 131 in the spinach planted in the open in Beijing and Tianjin recently, how are the detailed conditions? Have influence on public health? Inspect in the spinach which the Ministry of Health plants from Beijing, Tianjin and Henan area in the open on April 5 by random samples and find micro- radioactive iodine - 131, the content is 1-3Bq/kg respectively. Because of iodine of detection - 131 traces, the situation has not influenced public health at present. 2.Why choose the spinach to measure? The vegetables radioactive pollution monitoring experience shows in the nuclear accident previously: Large leaf, vegetables with small fine hair of surface growing in the open are apt to absorb the radioactive material subsiding in the air. So, choosing the spinach to measure is can be in order to find whether the vegetables are polluted by the radioactive material earlier. Practice has proved, can reduce the radioactive material on the surface of vegetables to wash effectively with water. 3.Iodine - 131 of detection happen to appear after the rainfall in open-air spinach this time, what does it have to do with the two? The radioactive material in the air will subside to the ground finally. Because of the intersection of air and the intersection of medium-level radioactive substance and the intersection of density and trace very much in our country at present, the vegetables radioactive pollution caused is generally difficult by detection that it subsides. The light rain appears in Beijing, Tianjin area recently, the rainfall accelerated the subsiding of the air medium-level radioactive substance, and the light rain makes these materials can have been retained and has not been washed away on the surface of the spinach again, so micro- iodine - 131 of detection in spinach sample. 4.Does the radioactive nuclide of the food find result and air find whether the result has relevance? Radioactive material in the air subside, can pollute ground and food of vegetables,etc. that grow in the open. The higher the density of the air medium-level radioactive substance is, the more radioactive materials of surface of vegetables subsiding to the ground and growing in the open are. The sleet weather can accelerate the subsiding of the air medium-level radioactive substance. 5.Is the work measured to food and drinking water now how to be disposed and launched? After the accident of Fukushima nuclear power station of Japan happens on March 11, 2011, Ministry of Public Health disposes the Northeast and coastal area relevant organization and does food and drinking water well and monitors the preparation rapidly, China's disease accuses of centre's working out and finishing the training technique scheme and carrying on the technical training to the detection personnel of relevant organizations. After on the 26th the country is nuclear to meet an urgent need to coordinate the committee to announce that detects iodine - 131 in the air, Ministry of Public Health trusts Center for Disease Prevention and Control of China in Liaoning immediately, 14 provinces and cities such as Hebei, Jiangsu, Zhejiang, Beijing, Shanghai, Guangdong, Shandong,etc. have launched the food and radioactive monitoring of drinking water. 6.Increase with the regional rainfall gradually, will the pollution of radioactive nuclide be more and more serious in the food and water? What safeguard procedures can the public take? This depends on the density of the air medium-level radioactive substance. The density of the air medium-level radioactive substance depends on the quantity of the radioactive material that Fukushima nuclear power station of Japan releases in and duration, and meteorological condition is (such as wind direction, wind speed and atmospheric circulation) . Rainy the intersection of time and size and the intersection of rainfall and size will influence the intersection of vegetables and radioactive level of pollution of material directly. The monitoring result trace of radioactive nuclide in the food, will not influence public health at present, do not need to take the safeguard procedures. Ask the public to pay close attention to the fact government's authority releases, in order to know situation progress. Weather bureau: The air of cold influences the northern Middle Eastern Department area of our country to fall on water 6th - 9th, in the middle part of east central area of Qinghai-Tibet Plateau, Gansu, there is slight to moderate snow (rain) in places such as the north,etc. in east central area of the Inner Mongol, the Northeast Or rain and snow mixed, among them, there is moderate or heavy snow, office ground snow storm in some areas of the east of Qinghai; Influenced together by the air of changes in temperature, there is drizzle or moderate rain or shower precipitation weather course in the most areas of Middle Eastern Department of our country. On 6th - 8th, influenced by cold air, east of the Northwest, the Inner Mongol, the Northeast, North China and other places can reach 6- 8 �� to lower the temperature, the office can reach 10- 12 ��. The Inner Mongol the greater part, the intersection of the Northwest and east, North China, the Northeast and other places have wind of force 4- 6. There is blowing sand or floating dust in some areas of places such as South Sinkiang basin, Midwest, the Inner Mongol of Xinjiang,etc.. Predict it as follows specifically: From 08 on the 6th to 08 on the 7th, in the middle part of east central area of Qinghai-Tibet Plateau, Gansu, have the slight to moderate snow (rain) with places such as the west,etc. in east central area of the Inner Mongol, north of the Northeast Or rain and snow mixed, among them, there is moderate or heavy snow, office ground snow storm in some areas of the east of Qinghai; The southeast of Tibet, east of the Northwest, Northeast and the southwest of North China, yellow there is drizzle or moderate rain or shower in places such as west of the Huaihe River and south, river Chinese west, the greater part of river the Huaihe River, the South, the west of South China, the north of southwest and east central area,etc.; The Inner Mongol the greater part, the intersection of the Northwest and east, North China, the Northeast and other places have wind of force 4- 6. There is blowing sand or floating dust in some areas of places such as South Sinkiang basin of Xinjiang, west of the Inner Mongol,etc.. There will be force 6- 7 in the Bohai Sea, there is Northeastern wind of force 5- 6 in the sea area of the Taiwan Straits, the South China Sea Northeast. From 08 on the 7th to 08 on the 8th, in the middle part of east central area of Qinghai-Tibet Plateau, Gansu, there is slight to moderate snow (rain) in places such as the north,etc. in Northeast of the Inner Mongol, the Northeast Or rain and snow mixed; There is drizzle or moderate rain or shower in places such as the southeast of Tibet, the greater part of southwest, yellow Huainan portion, river Chinese south, river the Huaihe River, the South, north of South China and west,etc.. There is wind of force 4- 6 in the greater part, east of North China,etc. place of north the greater part of the Inner Mongol, the east.

There will be wind of force 4- 7 in the sea area of East China Sea, the Taiwan Straits, the South China Sea Northeast. From 08 on the 8th to 08 on the 9th, there is slight to moderate snow (rain) in Northeast of the Inner Mongol, Heilongjiang northwestern part, the southeast of Tibet Middle Eastern Department, Qinghai, west plateau of Sichuan and other places Or rain and snow mixed; Tibet the southeast, the intersection of southwest and the greater part, the intersection of Hubei and south, the intersection of river and Huainan portion, the South, the intersection of South China and the intersection of west and north,etc. and place there is drizzle or moderate rain or shower; The greater part of the Inner Mongol, the Northeast and other places have wind of force 4- 6. There is blowing sand or floating dust in some areas of the west of the Inner Mongol.
