A record 1.8 million becquerels of beta-ray sources per liter of water were detected at a monitoring well at the crippled Fukushima No. 1 nuclear power plant, operator Tokyo Electric Power Co. said Dec. 13.
A record 1.8 million becquerels of beta-ray sources per liter of water were detected at a monitoring well at the crippled Fukushima No. 1 nuclear power plant, operator Tokyo Electric Power Co. said Dec. 13.
The reading concerns strontium and other beta-ray sources.
The water was sampled at a monitoring well in an area close to the sea near the No. 2 reactor building on Dec. 12. The well is located close to trenches holding highly radioactive water.
TEPCO said the reading apparently spiked after highly radioactive water seeped into the surroundings through failed parts of the trenches.
