1. Comparison of regulatory limits for fishery products
＊The regulatory limit, even the provisional regulation values, of Japan is lower.
Difference ?
Codex: 1 mSv/year
→ Contamination rate 10 % → 1000 Bq/kg
Japan: 1 mSv/year
→ Contamination rate 50 % → 100 Bq/kg
* This index includes S-35, Co-60, Sr-89, Ru-103, Ce-144, Ir-192
The reason for 500 →　100
○ Based on current scientific knowledge, commodities that meet current provisional regulation values are considered to be safe, and in fact food safety is basically secured. However, to achieve further food safety and consumer confidence, Japan is planning to reduce maximum permissible dose from 5 mSv/year to 1 mSv/year.
