TOKYO, Oct 20 — “More so-called hotspots were found in Tokyo and other areas far from the wrecked Fukushima nuclear plant,” reports Bloomberg’s Chisaki Watanabe. Two of these areas had radiation levels “exceeding safety limits”.

Local officials in Higashimurayama, Tokyo measured radiation at 2.153 microsieverts per hour, equal to a dose of 11.32 millisieverts per year according to a science ministry formula. That’s over 11 times the internationally recommended safety level for the general public.

And in Saitama prefecture to the north Tokyo, 111 brands of tea leaves were found to contain more than the government safety standard of 500 becquerels per kilogram of cesium. The highest measurement was 2,150 becquerels per kilogram.
