Grave new warning about Fukushima’s radioactive water leaks

Japan to issue gravest Fukushima nuclear warning in two years  Toronto Sun, KENTARO HAMADA AND JAMES TOPHAM, REUTERS, AUGUST 21, 2013 03 TOKYO – Japan will dramatically raise its warning about the severity of a toxic water leak at the Fukushima nuclear plant, its nuclear watchdog said on Wednesday, its most serious action since the plant was destroyed by an earthquake and tsunami in 2011.

The deepening crisis at the Fukushima plant will be upgraded from a level 1 “anomaly” to a level three “serious incident” on an international scale for radiological releases, a spokesman for Japan’s Nuclear Regulation Authority (NRA) said.

That will mark the first time Japan has issued a warning on the International Nuclear Event Scale (INES) since three reactor meltdowns after the massive quake in March 2011.

Water still leaking from the plant is so contaminated that a person standing close to it for an hour would receive five times the annual recommended limit for nuclear workers in a year…… The leak, which has not been plugged, is so contaminated that a person standing 50 cm (1.6 feet) away would, within an hour, receive a radiation dose five times the average annual global limit for nuclear workers.

After 10 hours, a worker in that proximity to the leak would develop radiation sickness with symptoms including nausea and a drop in white blood cells.

Each one-step INES increase represents a tenfold increase in severity, according to a factsheet on the website of the International Atomic Energy Agency. http://www.torontosun.com/2013/08/21/japan-to-issue-gravest-fukushima-nuclear-warning-in-two-years
