Preventing Tainted Water at Troubled Plant's Unit from Leaking A Big Concern

Japan's Nuclear Safety Commission ( NSC) said Monday its biggest concern regarding the elevated radiation levels in the water at the Fukushima No. 1 nuclear power plant's unit 2 was to prevent the tainted water from leaking into underground soils, water and seawater.

Radiation levels of 100,000 times more than water ordinary found in the reactor water were discovered in water on the underground floor of the turbine building at the unit, according to a statement distributed by the commission at a press conference in Tokyo Monday evening.

The commission said the operator should speed up the removal of the tainted stagnant water and be very careful about radiation protection of workers for continued recovery works.

The NSC also urged to carry out underground water samplings and more precise seawater samplings.
