Tokyo Electric Power Co., the operator of the crippled Fukushima Daiichi nuclear plant has revealed that they have found 1.9 million becquerels per liter of radioactive substances at the No. 2 reactor, the highest it has been since the nuclear meltdown in March 2011. The discovery of high levels of radioactive cesium in the groundwater at the No. 4 reactor has led them to suspect there is a new leak in the plant.
Previously, the highest level recorded was 1.8 million becquerels at the No. 1 reactor just last December 13. It is suspected that the radioactivity in the groundwater in No. 2 has been rising since November. Their latest tests at No. 4 has shown that there might be another source of leakage into the ocean. The water samples taken from 25 meters beneath the well facing the ocean shows that they contain 6.7 bq/liter of Cesium 137 and 89 bq/liter of strontium, plus other radioactive substances.
But TEPCO officials say it’s still too soon to say that there is indeed a new leak and they need to conduct more tests to check whether or not the numbers may have just been wrong. There is that possibility because the radioactive substances may have just been mistakenly mixed when they were getting the sample. It was only in July this year that the operator admitted that the contaminated water from the plant has leaked into the ocean. Since then, there were two major leaks; a 300-ton leak in August and 430 liters in October. These incidents have put at risk the nearby communities and putting the international spotlight on the delayed and error-stricken decontamination efforts at Fukushima.
