As a result of the accident at the Fukushima Dai-ichi Nuclear Power Plant on March 11, 2011, radioactive materials were released into the surrounding environment. To determine the degree and extent of contamination by radioactive materials, especially radioactive cesium (Cs), we have carried out the field survey in Fukushima prefecture and surrounding region. The field surveys were repeated every year to monitor the change of radioactive Cs concentration. The results of these survey were published at the web site of Ministry of agriculture, forestry and fisheries. For more convenient use, we make data sets of these surveys, including sampling sites, sampling date and concentration of ^<134>Cs, ^<137>Cs and total radioactive Cs from 2011 to 2014 (5 times survey).
