Monitoring of the content of radioactive particles in meals has been conducted by the prefectural government. The sampling was made by randomly collecting meals prepared for 78 residents in 7 different areas within Fukushima prefecture. The meals were divided into three categories by the consumers’ age groups: 0-1 year, 1-12 years and 13 years and above. The tests showed that 3 meals contained strontium. Strontium was found in one meal for age group 1-12 years and in one for over 13 years in the north of Fukushima prefecture, and in one for the 1-12 years group in the center region. The meals contained 0.016 to 0.034 Bq/kg of strontium. The prefecture calculated the amount of strontium per day assumed from eating such a meal: 0.071Bq/kg maximum. The prefecture says that if a meal containing such amounts of strontium is eaten every day for one year, the annual internal exposure to radiation would measure 0.00073 mSv (0.73 µSv). The conclusion was that “the impact of the amount of strontium detected will be very small”. No plutonium was found in these tests.
