(Adds comparison with Chernobyl, mechanisms of radiation spread, cesium risk.)

March 15 (Bloomberg) -- The danger of radiation leaks from Tokyo Electric Power Co.’s Fukushima Dai-Ichi nuclear plant is rising after explosions at the site caused by Japan’s earthquake and tsunami, Prime Minister Naoto Kan said today.

As of 10:22 a.m. local time, radiation as high as 400 millisieverts was detected at the plant’s No. 3 reactor, Chief Cabinet Secretary Yukio Edano said at a briefing. That’s 20 times the annual limit for nuclear industry employees and uranium miners, according to the World Nuclear Association, a London-based advocate for the nuclear energy industry. A radiation dose of 100 millisieverts a year is the lowest level at which any increase in cancer is evident, the London-based WNA said on its website.
