Radioactivi-Thé

Radioactivity levels above normal has been detected in tea fields near Tokyo.

According to local authorities, the presence of 570 becquerels of cesium per kilogram was found on tea leaves grown at Minamiashigara in Kanagawa Prefecture, south-west of the capital.

Much of the production of quality teas from Japanese prefectures are from the south of the archipelago. However the prefecture has suspended sales of tea and asked for the recall of products already shipped, although the level of cesium is not considered dangerous to humans. Nevertheless opinions differ about the health risks of radioactivity levels in tea. Tea leaves are actually considered as vegetables and therefor subject to the same limit of cesium than any other plant food (500 becquerels per kilogramme).
