title: [Radiation screening test for commercial food products and foodstuffs for food services using NaI (Tl) scintillation survey meter].
abstract: Screening tests were carried out for radioactive cesium in foods using a NaI (Tl) scintillation survey meter. The screening level was set at 250 Bq/kg, and specimens exceeding this level were scheduled to be sent to an external testing organization, which would conduct further tests using a germanium semiconductor detector. Some specimens that did not reach the screening level were also sent to the same organization. Foodstuffs used in commercial food products circulated in Chiba city were targeted, along with food services provided to schools and day care centers. In all, 495 specimens were tested; however, no specimens exceeded the screening level. The results of verification tests confirmed that no specimen exceeded the tentative regulatory limit.
