According to the results of the analysis by the Tokyo Electric Power Co. on April 14, the level contamination in the underground water around Nos. 1 and 2 reactors of the plant is on the increase.

It was reported that radioactive iodine-131 of 400Bq per one cubic meter was detected in underground water around the building that houses turbine of Reactor No. 1 on April 13. This was six times the level measured a week before. Radioactive cesium-134 of 53Bq was also detected there. This means a 38-fold jump a week.

The concentration of iodine and cesium showed a 17- and 8-fold increase respectively in underground water near Reactor No. 2.

Experts are of the view that a high level of contaminated water is soaking into the ground from Reactors Nos. 1 and 2 at present to contaminate underground water.

This is causing the damage by radioactivity to expand.

Radiation of 516Bq per kg was detected when fishes contaminated by radiation were found in the waters off Fukushima Prefecture for the first time. The level of radiation rose to 12 500Bq at present.

In this regard the Japanese government predicted that radioactive materials would be spread to areas 500 km away from the waters off the prefecture after April 15.

According to south Korean MBC, it was confirmed that radioactive materials which contained in the rain that fell in the area south of the Korean Peninsula on April 7 reached the peninsula by the eastward wind.

The National Police Agency of Japan said that the death toll caused by the quakes and the ensuing tsunami increased to 13 591 and the number of those unaccounted for to 14 497 as of 19:00 on April 15.

Aftershocks are going on.

On April 14 the quake which registered 6.1 on the Richter Scale rocked the eastern area of Japan.

Its epicenter was 10 km deep under the waters off Sanriku, Iwate Prefecture.
