6 days of bulletins weigh Ministry of Public Health, detect in the spinach that cultivates in open air of and other places of Beijing, Tianjin, Henan an iodine – 131. Carry out a proof, rinse the radioactivity material that can reduce vegetable surface effectively with water. Current, radionuclide of the minim in food won’t affect public health, need not adopt preventive measure.
Beijing ferry comfort produces spinach to be given by check radioactivity material
According to bulletin of Ministry of Public Health, the radioactivity that the sampling observation in the spinach that door of Ministry of Public Health cultivated from Beijing, Tianjin and Henan area open air on April 5 discovers minim is iodic – 131, content is 1-3Bq/kg respectively. The iodine that gives as a result of check – 131 minim, do not have an influence to public health.
Ministry of Public Health expresses when explaining the problem that why chooses spinach to undertake detecting, pollute the experience that monitor to make clear toward radioactivity of the vegetable in nuclear accident already: The radioactivity material that the vegetable and easy adsorption that shows the great part of a historical period that grows inherently, surface to have tiny nap sedimentations in air. Accordingly, choice spinach detects can discover whether vegetable is polluted by radioactivity material early. Carry out a proof, rinse the radioactivity material that reduces vegetable surface effectively with water.
Spit makes radioactivity material is put take spinach appearance
Ministry of Public Health points out, the radioactivity material in air can sedimentation finally on the ground. Because air of our country churchyard is at present medium infinitesimal of radioactivity material chroma, its sedimentation the vegetable radioactivity pollution that cause is general hard check goes out. Beijing and other places appeared recently spit, rainfall quickened material of the radioactivity in air sedimentation, and spit makes these material can be put again stay in spinach surface to was not swept, in spinach sample so check gave minim iodine – 131.
The radioactivity material in air sedimentations the food such as the vegetable that can pollute the ground and open air to grow. The concentration of material of the radioactivity in air is higher, sedimentation the radioactivity material of the ground and the vegetable surface that dew grows inherently is more. Pluvial Xue Tian enrages what can quicken material of the radioactivity in air to sedimentation.
Radionuclide of the minim in food won’t affect health at present
After accident of nuclear power plant of Japanese blessing island happened on March 11, 2011, the orgnaization does Ministry of Public Health related quick disposition northeast and foreland good food and drinking water monitor preparative work, chinese disease accuses central work out to finish groom technical program is right of concerned orgnaization detect personnel undertook the technology grooms. Lash-up of nucleus of 26 days of countries is harmonious appoint in announcing air, detect an iodine – 131 hind, ministry of Public Health entrusts Chinese disease to prevent control center to was in the 14 provinces city such as Liaoning, Heibei, Jiangsu, Zhejiang, Beijing, Shanghai, Guangdong, Shandong to begin food and drinking water radioactivity to monitor the work instantly.
Increase gradually as each district rainfall, is the radionuclide in food and water polluted can more and more serious? Ministry of Public Health expresses, this depends on the chroma of material of the radioactivity in air. The chroma of material of the radioactivity in air depends on the quantity of the radioactivity material that nuclear power plant of Japanese blessing island releases and duration, and weather condition (if wind direction, wind speed and air are circumfluent,wait) . Rain time length and the contaminative level that rainfall size can affect vegetable radioactivity material directly.
Ministry of Public Health expresses, food is at present medium the minim of the result that monitor of radionuclide, won’t affect public health, need not adopt preventive measure. The government sector will release progress circumstance in time.
