New radiation hotspots prompt Japan to extend monitoring
The discovery of radiation hotspots well beyond the exclusion zone
around the Fukushima Dai-Ichi nuclear plant has forced the
Japanese government to increase its monitoring from six to 22
prefectures in the east of the country.

AP - Elevated levels of radiation have been found 125 miles from
the power plant, which was destroyed by the March 11 earthquake
and tsunami. That is well beyond the 18-mile exclusion zone that
has been imposed.
Officials in the city of Tokamachi, in northwest Niigata
Prefecture, detected 27,000 becquerels of radioactive cesium per
kilogramme (2.2lbs) of waste in a school compost heap. By law, any
waste containing just 8,000 becquerels per kg must be treated as
radioactive waste.
Experts and residents say the government should have begun
monitoring further afield immediately after the plant began
leaking radioactivity.
"Since the first week of the disaster, authorities have slowly
been announcing that they would start checking fish, seaweed,
vegetables for radiation," said Tom Gill, a British professor of
anthropology at Meiji Gakuin University who is studying
communities in the disaster zone.
"And the response in each case has - quite reasonably - to ask why
it wasn't done previously," he said. "And this is no different."
As well as being slow to broaden the monitoring, Mr Gill says the
figures being provided by the authorities are "extremely
inconsistent."
The education ministry, charged with compiling data, says on its
web site that the maximum level of radiation in Fukushima
Prefecture at present is 2.3 microsieverts per hour, while
elsewhere on the same site it is showing a reading of 16.2
microsieverts in the hamlet of Nagadoro, on the edge of the
exclusion zone.
"Not only is that figure extremely high, but it's not going down,"
said Gill. "The village authorities' official line is that the
residents will be able to go back in two years, and that might be
so in some areas, but it is almost certainly out of the question
for other areas."
