KBS GlobalJapanese media say the Tokyo Electric Power Company (TEPCO) reported lower than actual levels of radioactivity in waters around the Fukushima Daiichi nuclear plant for nearly two years.
Kyodo News and NHK report TEPCO briefed Japan’s Nuclear Safety Commission on Saturday about what Japan’s largest electrical utility called an unintentional error.
TEPCO said the inaccurate measurements were taken from July 2011 until May this year, resulting in concentration levels of radioactive cesium being reported some becquerels lower than the actual level. It said the measurements were taken one-point-three kilometers south of the nuclear plant.
The company said it corrected the problem last June.
