Cesium-137 結果共2筆

The Food and Drug Administration (FDA) announced that two kilograms of green tea powder imported from Japan were destroyed at the border due to trace amounts of radioactive cesium-137. The batch’s cesium-137 levels were within the acceptable limit of 100 becquerels per kilogram, but the FDA emphasized the importance of ethical practices and urged businesses to adhere to them. The FDA tested the batch on October 31 and found 3 becquerels per kg of cesium-137 and 3 becquerels per kg of cesium-134 plus cesium-137. Since last year, food from five prefectures of Fukushima, Japan, has been imported to Taiwan, provided it meets radiation and origin inspection requirements. The FDA’s regulations for cesium-134 and cesium-137 levels in various food categories are based on the ＂Standards for the Tolerance of Atomic Dust and Radioactivity Contamination in Foods.＂ From 2011 to 2023, Taiwan has tested 224,970 batches of Japanese food, with 252 samples showing trace radioactivity that did not exceed national or Japanese standards.

A university research report recently pointed out that the explosion testing of American and Russian nuclear bombs around 60 years ago, released high levels of Cesium-137 into seawater.
