238km (148 miles) away from the damaged nuclear plant in Fukushima, leafy vegetables in Tokyo have tested positive for cesium contamination.

Radiation is spreading across Japan, even though winds had been blowing out towards the Pacific most of the time. Also, more prefectures nearer to the Fukushima Daiichi nuclear plant are turning up signs of radiation contamination, mainly iodine-131.  Water supplies as far south as Tokyo have shown signs of iodine-131 contamination.
