About radiological test result of food which we carried out in 2020
We publish no*suisambutsu from the city and test result of radioactive material of distribution food that we carried out in 2020.
For more information about result, please see the details as a result of every type of food.
Test result that Motoichi carried out in the past
As we publish test results from 2011 when Motoichi enforced to 2019 every year, please see.
About the standard value of radioactive material (radioactive cesium) in food in the food hygiene law
About radioactive material, the standard value is set in the food hygiene law as radioactive cesium.
Comparative half-value period is long, and, about nuclide targeted for regulation, it is said that you should do with nuclide that it is necessary to consider long-term influence, and half-value period steals cesium, strontium, ruthenium, plutonium which are nuclides or more with regulation object for one year and, about nuclide except cesium, calculates the ratio with cesium, and the standard value of radioactive cesium is set that additional internal exposure dose adds up and does not exceed 1mSv a year.
In setting of the standard value, we subdivided age group or sex and were set to be less than the severest value from that, and sensitivity to age group and radiation that there were many intakes of food was considered enough to high child and infants said to that we were promising.
As for the material on setting the standard value, please see leaflet (Ministry of Health, Labour and Welfare) [PDF] (the outside site).
The standard value of radioactive material (radioactive cesium) in food
Classification of food
The standard value
|Food for baby/infant|
With detection limit level
It varies according to target item, precision, measurement time of measuring equipment and, about the detectable minimum density, is calculated automatically.
