» New leak was found, highest reading is 1,800 millisieverts per hour

Very high radiation levels were observed on Aug 31st at three tanks and one of the pipes connecting them at Fukushima Daiichi nuclear plant, it might be the new leakage according to TEPCO.

The radiation readings were from 70 to 1,800 millisieverts per hour, although none of the tanks showed any visible drop in their water levels.

The tanks are built of steel plates held together by bolts, the same structure as the tank that was found last week to have leaked 300 tons of highly toxic water.There are 350 of the same type of tanks at the site. This bolt type tank is a temporary measure and it last only 5 years.

On Sep 1st, TEPCO said it had detected 920 becquerels per liter of radioactive substances emitting beta rays, such as strontium-90, in a drainage ditch located south of the H4 area, compared with 580 becquerels recorded on Aug. 22. The drainage ditch leads to the Pacific.
