Japan’s Tokyo Electric Power Co (TEPCO) is again in the midst of controversy for failing to timely report on record radiation levels at the crippled Fukushima nuclear plant. It is now blasted for holding back strontium measurements since September.
Two magnitude-5 earthquakes struck off the coast of Japan’s Fukushima prefecture, the site of the 2011 tsunami and earthquake that killed more than 18,000 people and sparked the world’s worst nuclear disaster since Chernobyl.
TEPCO has revised the readings on the radioactivity levels at the Fukushima No. 1 nuclear plant well to 5 million becquerels of strontium per liter – both a record, and nearly five times higher than the original reading of 900,000 becquerels per liter.
About 1,400 people have filed a joint lawsuit against three companies that manufactured Japan's Fukushima Dai-ichi nuclear plant, saying they should be financially liable for damage caused by its 2011 meltdowns.
The operator of the crippled Fukushima nuclear power plant is erecting an underground wall of frozen soil, which would hopefully stop radioactive water from running into the sea. However, doubts remain over whether it will fix the leak problem.
