According to the radiation monitoring at 18.00 on April 04,2011 the concentration of I-131, Cs-134 and Cs-137 do not threat to people in China, because this concentrations thirty-forty thousand times (30,000-40,000 times) lower, than established norms of radiation safety, which are used for human security in all conditions exposure to ionizing radiation artificial or natural origin. Radiation safety standards establish the basic dose limits, permissible levels of exposure to ionizing radiation to limit the exposure of the public. We do not do a radiation monitoring in China and only provide official data from the official Chinese points of radiation monitoring in China. On our website first appeared the accurate data about the levels of concentration of radioactive isotopes in China, in English and Russian languages, because we want to show, that the accident at the nuclear power plant in Japan do not threat to people in China.
