Under the Food Sanitation Act, the standard limits were established and enforced on April 1, 2012.
(Quotation: Consumer Affairs Agency, Government of Japan)
Radionuclides | Japan | Codex Alimentarius Commission | EU | US |
---|---|---|---|---|
Radioactive cesium | Drinking water...10 | Drinking water...1,000 | All food...1,200 | |
Milk...50 | Milk...1,000 | |||
Infant food...50 | Infant food...1,000 | Infant food...400 | ||
General food...100 | General food...1,000 | General food...1,250 | ||
Upper limit value of additional dose | 1mSv | 1mSv | 1mSv | 5mSv |
Estimated values of the proportion of food containing radioactive substances | 50% | 10% | 10% | 30% |
It is not possible to simply compare the numerical values because the reference values (standard limits) were established by taking into account the estimated impact of the amount of food ingested, the proportion of food containing radioactive substances, etc. The Codex Alimentarius Commission, EU, and Japan have designated the upper limit of additional doses as being 1 mSv/year.
