Radiation levels spike to record high in Fukushima groundwater well nearby ocean — Trench failures to blame, says Tepco — Million times more strontium/beta-ray source than cesium

Record radiation levels detected in well at Fukushima nuke plant [...] 1.8 million becquerels of [strontium and other] beta-ray sources per liter of water were detected 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.
