Standard Limits Applied from April 2012
Even based on the provisional regulation values applied up to March 2012, safety of foods in conformity thereto was guaranteed in terms of the effects on human health. However, from the perspective of further ensuring the security and safety of foods, the current standard limits were established and have been applied since April 1, 2012.
First of all, the provisional regulation values for radioactive cesium and strontium were based on the premise that the annual radiation dose from foods does not exceed 5 mSv.
The present standard limits are set so that the annual radiation dose from foods should not exceed 1 mSv (p.55 of Vol. 2, "Approach for the Establishment of the Standard Limits ◆ Grounds for the Standard Limits"). Additionally, foods were classified into five categories for the provisional regulation values, but were newly classified into four for the present standard limits (for details, see p.52 of Vol. 2, "Food Categories [Reference]").
(Related to p.174 of Vol. 1, "Indices Concerning Radioactive Materials in Foods," p.57 of Vol. 2, "Approach for the Calculation of the Standard Limits (1/2)," and p.58 of Vol. 2, "Approach for the Calculation of the Standard Limits (2/2)")
