The distance gets farther and farther - Another case of cesium in tea leaf that exceeds allowable limits

This time in Shizuoka, over 300 kilometers away from Dai-ichi

From NHK:

Radioactive cesium exceeding the legal limit was detected in tea made in a factory in Shizuoka City, more than 300 kilometers away from the Fukushima Daiichi nuclear power plant. Shizuoka Prefecture is one of the most famous tea producing areas in Japan.

A tea distributor in Tokyo reported to the prefecture that it detected high levels of radioactivity in the tea shipped from the city. The prefectural government confirmed the contamination on Thursday, detecting 679 becquerels per kilogram of radioactive cesium. The legal limit is 500 becquerels.

The prefecture ordered the factory to refrain from shipping out the product.

After the accident at the Fukushima nuclear power plant, radioactive contamination of tea leaves and processed tea has been found over a wide area around Tokyo.

Starting last month in Shizuoka Prefecture radioactive cesium has been detected in tea leaves and processed tea from many production areas, including Shizuoka city, up to the level of about 460 becquerels per kilogram.

This is the first time that cesium beyond the legal limit was found in tea leaves picked in the prefecture.

Why is this happening? Is it due to recent airborne contamination or is this the first time they tested tea in this area?
