radiation levels rise in tokyo

'Radiation levels rise in Tokyo as nuclear crisis deepens March 15, 2011 - 5:20PM'

"We monitored a higher than normal amount of radiation in the morning in Tokyo, but we don't consider it to be at a level where the human body is affected," said Sairi Koga, an official of the Tokyo Metropolitan Government.

Another city official said 0.809 of a micro-sievert was measured between 10am and 11am in Tokyo today. Jiji Press said this figure was 20 times higher than on Monday.

Kan warned people living up to 10 kilometres beyond a 20km exclusion zone around the nuclear plant to stay indoors or risk radiation sickness.

The fire, which was later reported to be out, had burned in the plant?s No 4 reactor, he said, meaning four out of six reactors at the facility were in trouble.

As of 10.22am local time, 400 millisieverts of radiation were detected at the No. 2 and No. 3 reactors, Chief Cabinet Secretary Yukio Edano told reporters. That is 20 times the annual limit for nuclear industry employees and uranium miners, according to the World Nuclear Association.
