Cleanup crews trying to mitigate Japan’s never-ending radiation crisis at Fukushima ran into more problems recently after sensors monitoring a drainage gutter detected a huge spike in radiation levels from wastewater pouring into the Pacific Ocean.
The Tokyo Electric Power Company says radiation levels were up to 7 000 percent higher than normal, prompting an immediate shutdown of the drainage instrument.
The first readings came around 10 a.m. local time on February 22, setting off alarms not once but twice as radiation levels spiked to extremely high levels.
“The levels of beta ray-emitting substances, such as strontium-90, measured 5,050 to 7,230 becquerels per liter of water between 10:20 a.m. and 10:50 a.m.,” reported The Japan Times.
“TEPCO requires radioactivity levels of groundwater at the plant discharged into the sea to remain below 5 becquerels.”
TEPCO shut off the leaky gutter, but radiation continued to spike throughout day.
The gutter was quickly decommissioned to prevent further radiation emissions, but the leaks reportedly continued throughout the day, with radiation levels hovering between 10 and 20 times higher than normal.
TEPCO says it doesn’t know what caused the sudden radiation spikes.
