» Highest radioactivity found at the ditch near the sea

The highest level of beta ray-emitting radioactive substances, such as strontium, has been detected at one point in a drainage ditch at the Fukushima No. 1 where measurements are regularly taken TEPCO said on Oct 17th.

According to TEPCO, a water sample taken on Oct 15th at a point in the ditch some 300 from the ocean meterscontained 19 becquerels of such radioactive substances.However, after the passage of massive Typhoon Wipha, the sample taken on Oct 16th at the same point was found to contain 1,400 becquerels per liter of beta ray-emitting radioactive substances, more than 70 times higher than before the typhoon and the highest level ever detected at the same point.TEPCO said water that passed through the ditch may have entered the sea.
It is thought the rain washed out radioactive substances that had been absorbed by the ground.
