Results of the activity concentration measurements in Hungary (updated on 6 April 2011 at 17.00)

2011.04.07

In Hungary several institutions are checking the radioactive components of the air in a coordinated way. The sampling is carried out in special equipment aspirating air from the environment for several days through special filters. The radioactivity of the removed filters is measured also for a long time with very sensitive detectors. Radioactive materials originated from the Fukushima accident in Japan can be detected in Hungary, too. The results from the measuring institutions are sent to the Hungarian Atomic Energy Authority and the summary of the results with some explanation is published on the website of the HAEA. The very low activity concentration of radioactive materials detected in Hungary so far has negligable effect and no risk at all to public health and the environment. The measurement results of the national environmental radiation monitoring system do not show any increase in the ambient dose rate. (The ambient dose rate data can be seen on the website of the National Directorate General for Disaster Management of the Ministry of Internal Affairs
