Richard Wakeford, a professor at the Dalton Nuclear Institute at the University of Manchester, comments on the risks of nuclear radiation following the damage at the Fukushima Dai-Ichi atomic plant. He made the remarks in a telephone interview today.
Efforts to repair the cooling systems at the No. 2 and No. 3 reactors at the Fukushima Dai- Ichi nuclear plant are being delayed by the need to drain radioactive water from the floors, Tokyo Electric Power Co. said.
Japan raised the severity rating of its nuclear crisis to the highest, matching the 1986 Chernobyl disaster, after increasing radiation prompted the government to widen the evacuation zone and aftershocks rocked the country.
Radioactivity in fish exceeding health guidelines was detected for the first time off northern Japan as Tokyo Electric Power Co. dumped tainted water into the ocean to gain control of its crippled nuclear plant.
Japan’s crippled nuclear station is yet to stabilize and the reactors must be kept cool to prevent the crisis from deteriorating, the U.S. atomic regulator said, as more aftershocks rocked the country.
