Nuclear watchdog's view

Japan's nuclear safety watchdog says it believes radioactive elements from
melted nuclear fuel have found their way from one of the reactors at the damaged
Fukushima Daiichi plant to a turbine building here.

Radiation levels 100,000 times that found in water in an normally operating reactor were detected in water puddles in the Number 2 reactor's turbine building on Sunday. High
radiation figures were earlier recorded at similar locations at the Number 1 and
3 reactors.

The Nuclear Safety Commission, an independent body, says the
radiation level at the Number 2 reactor was dozens of times that of the other
two reactors.

The commission says that radioactive substances from
temporarily melted fuel rods at the Number 2 reactor had made their way into
water in the containment vessel and then somehow leaked out.

The commission says the radioactive water should be removed as soon as possible to
ensure the safety of workers.

The commission says the most immediate
concern is the possibility of highly radioactive water seeping into the ground
and the ocean. It said it has asked Tokyo Electric to monitor radiation levels
in the ground water and seawater more closely.

The commission added that
injecting water into the Number 2 reactor from outside should be continued
because the high levels of radiation are being detected only inside the turbine
building.

The watchdog said pumping water into the Number 2 reactor will
not be affected even if highly radioactive water continues to leak from the
containment vessel.

More radioactive substances found in seawater

More high levels of radioactive material have been found in seawater near the
troubled Fukushima Daiichi nuclear power plant.

Tokyo Electric Power
Company says samples collected 30 meters from one of the plant's water outlets
on Sunday contained 46 becquerels per cubic centimeter of iodine-131. That's
1,150 times higher than the regulated standard level.

On Friday and
Saturday, water samples collected 330 meters south of another outlet showed
levels of iodine-131 that were higher than 1,000 times the standard level.
However, on Sunday the levels had dropped to 250 times the standard
level.

The government's nuclear safety agency says radioactive materials
may have leaked from the plant and drifted with the current from south to
north.

TEPCO is struggling to remove highly radioactive water from the
turbine buildings of 3 reactors before work to restore their cooling systems can
begin.

On Tuesday, the company intends to pump fresh water, instead of
sea water, into spent fuel storage pools of 2 reactors.

Fresh water was
pumped into the reactors by Saturday, to prevent the salt water from corroding
the cooling system.

Radioactive levels in the air are decreasing at most
observation points in the surrounding areas on Monday.

The reading in
Fukushima City, 65 kilometers northwest of the nuclear power plant, was 3.84
microsieverts per hour at 1 AM.

The annual total limit of radiation
exposure considered safe for humans is 1,000 microsieverts based on standards
set by the International Commission on Radiological Protection.
