japan pollution already come to china land

china mold maker, china toolmakers, china plastic injection molding, china plastic product, china rapid prototyping, china vacuum thermoforming: Earth on such a big, polluted when Japan, the world suffer together,
1. Recently open in Beijing and Tianjin detected in spinach grown in iodine -131, specifically, how are we? Whether the impact on public health?

The health sector on April 5 in Beijing, Tianjin and Henan Province in spinach grown in open-air sampling found traces of radioactive iodine -131, contents were 1-3Bq/kg. Since the detection of trace iodine -131, the current situation has no effect on public health.

2. Why spinach tested?

Past nuclear accident experience shows that monitoring of radioactive contamination of vegetables: the growth of large open-air leaves the surface of tiny villi of vegetables easily absorbed radioactive material deposition in the air. Therefore, the choice of spinach can be detected early detection of radioactive contamination of vegetables is to be. Practice has proved that water washing of vegetables can reduce the surface of the radioactive material.

3. The spinach in the open air in the detection of iodine -131 just after rainfall, the two have anything to do it?

Radioactive substances in the air will eventually settling to the ground. Because China's domestic air concentration of a trace amount of radioactive material, the settlement led to radioactive contamination of vegetables generally difficult to be detected. Recently in Beijing, Tianjin regions, light rain, rain accelerated the settlement of radioactive material in air, and rain and these substances can remain in the spinach was not washed away the surface, so the samples detected in the spinach Iodine -131.

4. Radionuclide test results of food and the air whether the correlation between test results?

Deposition of radioactive substances in the air can pollute the ground and open growth of vegetables and other foods. Air, the higher the concentration of radioactive substances, the settlement to the ground and open-air vegetable growing more radioactive material surface. Rain and snow can accelerate the deposition of radioactive material in air.

5. Now the work of food and drinking water testing is carried out how to deploy?

March 11, 2011 Fukushima nuclear power plant accident, the Ministry of Health, the rapid deployment of the Northeast and coastal areas relevant institutions on food and drinking water monitoring preparations, China CDC to complete the preparation of technical programs and related training institutions inspectors carried out technical training. 26, the National Nuclear Emergency Coordination Commission announced the detection of iodine -131 in the air after the Ministry of Health commissioned the China Disease Prevention and Control Center immediately in Liaoning, Hebei, Jiangsu, Zhejiang, Beijing, Shanghai, Guangdong, Shandong and other provinces and cities conducted in 14 food and drinking water radioactivity monitoring.

6. With the gradual increase in rainfall around, radionuclide contamination in food and water will more and more serious? Protective measures could be taken public?

It depends on the concentration of radioactive substances in the air. The concentration of radioactive substances in the air depends on the release of Fukushima nuclear power plant the amount of radioactive material and duration, and weather conditions (such as wind direction, wind speed and atmospheric circulation, etc.). Rainfall duration and rain will directly affect the size of the pollution level radioactive vegetables. Currently the monitoring of radionuclides in food of trace results will not affect the public health, without taking protective measures. Please release the public concern about the Government the authority to control the situation progress.
