Results of inspections on radioactivity levels in agricultural products (April 1, 2012 to March 31,2013)

Test results of radioactive cesium in foods have been made public everyday by the Ministry of Health, Labour and Welfare (MHLW) since March 2011. Following tables show the summary of the test results by each category of agricultural products since April 1st, 2012 in 17 prefectures to which the Government prescribes to conduct the test※. Specific data of each sample tested is available on the webpage of MHLW (http://www.mhlw.go.jp/english/topics/2011eq/). The concentration of radioactive cesium is quantified by Germanium semiconductor detectors or NaI Scintillation Detectors.

 Note: As the maximum limit, 100 Bq/kg applies to General Foods, 50 Bq/kg applies to Milk and Infant foods, and 10 Bq/kg applies to Drinking water including tea infusion under the new regulation as from April 1, 2012.

Note 1: All soy bean samples in the table are harvested and tested in FY 2012. As pulses are normally harvested at the specific time of the year, stored and distributed all through the year until the next harvest season, 1,564 soy bean samples harvested in FY 2012 were tested in FY 2013. The results is available on the following web page: Results of inspections on radioactivity levels in agricultural products.

Note 2: Including 8 soy beans which are under 500 Bq/kg (as a transitional measure, the provisional reguration value for general foods (500 Bq/kg) applied to soy bean until December 31,2012).
