Cesium-137 In Organic Blueberry Jam whatisradiation.com

The blueberries used in the Fiordifrutta brand originated in Bulgaria show levels of 164Bq/kg of cesium-137 according to the test commissioned by Shukan Asahi and 140Bq/kg of cesium-137 by test by the municipal (Tokyo) health authorities. The US limit is 1200 bq/kg and EU limit is 600 bq/kg, so the product is unlikely to be recalled in the USA.
