The Ministry of Health, Labour and Welfare commissioned the National Institute of Food and Drug Safety Evaluation to purchase foods actually circulated in 15 regions nationwide from September to October 2017. They estimated the annual radiation dose from radioactive cesium in food. The results showed that the radiation dose received by a person in one year from radioactive cesium in food is estimated to be between 0.0006 and 0.0011 millisieverts per year, which is less than 1% of the current standard limit of 1 millisievert per year, confirming that the dose is extremely small.

No exceeding of standard values

The Ministry of Health, Labour and Welfare commissioned the National Institute of Health Sciences to purchase foods actually circulated in 15 regions nationwide from February to March 2017, and estimated the annual radiation dose from radioactive cesium in food. The investigation found that the radiation dose from radioactive cesium in food for a person over one year is estimated to be between 0.0006 and 0.0010 millisieverts per year, which is less than 1% of the current standard limit of 1 millisievert per year, confirming that the dose is extremely small. The Ministry will continue to conduct similar surveys to verify food safety.

The Ministry of Health, Labour and Welfare commissioned the National Institute of Health Sciences to purchase foods actually circulating in 15 regions nationwide from September to October 2016 and measure the concentrations of radioactive strontium (Sr-90) and plutonium (Pu-238, Pu-239+240).

The Ministry of Health, Labour and Welfare commissioned the National Institute of Health Sciences to purchase foods actually circulated in 15 regions nationwide from September to October 2016. They estimated the annual radiation dose from radioactive cesium in food. The results showed that the radiation dose received by humans from radioactive cesium in food is estimated to be between 0.0007 and 0.0014 millisieverts per year, which is less than 1% of the current standard limit of 1 millisievert per year. This confirms that the dose is extremely small. The Ministry will continue to conduct similar surveys to verify food safety.

The Ministry of Health, Labour and Welfare commissioned the National Institute of Health Sciences to purchase and test foods actually circulating in 15 regions nationwide from September to October 2015 for the concentration of radioactive strontium (Sr-90) and plutonium (Pu-238, Pu-239+240). Some samples contained Sr-90, but all within pre-accident levels. No plutonium was detected.

The Ministry of Health, Labour and Welfare commissioned the National Institute of Food and Drug Safety Evaluation to purchase and analyze foods actually circulated in 15 regions nationwide from September to October 2015. The investigation estimated that the annual radiation dose from radioactive cesium in food is between 0.0006 and 0.0015 millisieverts per year. This is less than 1% of the current standard limit of 1 millisievert per year, confirming that the radiation exposure from food is extremely small. The Ministry will continue to conduct similar surveys to verify food safety.

The Ministry of Health, Labour and Welfare commissioned the National Institute of Health Sciences to purchase foods actually circulated in 15 regions nationwide from February to March 2015 and estimate the annual radiation dose from radioactive cesium in food. The investigation estimated that the radiation dose from radioactive cesium in food for a person over one year is between 0.0006 and 0.0020 millisieverts per year, which is less than 1% of the current standard limit of 1 millisievert per year, confirming that the dose is extremely small. The Ministry will continue to conduct similar surveys to verify food safety.

The Ministry of Health, Labour and Welfare commissioned the National Institute of Health Sciences to purchase and test foods actually circulating in 15 regions nationwide from September to October 2014 for concentrations of radioactive strontium (Sr-90) and plutonium (Pu-238, Pu-239+240). Sr-90 was detected in some samples, but all within pre-accident levels. Plutonium was not detected.

The Ministry of Health, Labour and Welfare commissioned the National Institute of Health Sciences to purchase foods actually circulated in 15 regions nationwide from September to October 2014. They estimated the annual radiation dose from radioactive cesium in food. The results showed that the radiation dose received by a person from radioactive cesium in food is estimated to be between 0.0007 and 0.0022 millisieverts per year, which is less than 1% of the current standard limit of 1 millisievert per year. It was confirmed that the dose is extremely small. The Ministry will continue to conduct similar surveys to verify food safety.

The Ministry of Health, Labour and Welfare commissioned the National Institute of Health Sciences to purchase foods actually distributed in 15 regions nationwide from February to March 2014 and estimate the annual radiation dose from radioactive cesium in food.

The Ministry of Health, Labour and Welfare commissioned the National Institute of Health Sciences to purchase and test foods actually circulating in 15 regions nationwide from September to October 2013 for concentrations of radioactive strontium (Sr-90) and plutonium (Pu-238, Pu-239+240). Some samples contained Sr-90, but all within pre-accident levels. No plutonium was detected. These results were consistent with previous surveys.

The Ministry of Health, Labour and Welfare commissioned the National Institute of Food and Drug Inspection to purchase and test foods actually in circulation across 15 regions nationwide from September to October 2012 and from February to March 2013 for radioactive strontium (Sr-90) and plutonium (Pu-238, Pu-239+240). Sr-90 was detected in some samples, but all within pre-accident levels. Plutonium was not detected.

The Ministry of Health, Labour and Welfare commissioned the National Institute of Health Sciences to collect and measure the concentrations of radioactive strontium (Sr-90) and plutonium (Pu-238, Pu-239+240) in foods. Samples included purchased foods (market basket samples) and meals prepared in households (shadow meal samples) across Japan from February to May 2012. Sr-90 was detected in some samples but within pre-accident levels. Plutonium was not detected.

As a result of analysis at the National Institute of Health Sciences, 188 out of 313 purchased products contained specified drugs (Note 1) and other substances.
