There is concern about radioactive contamination due to the accident at the Fukushima Daiichi Nuclear Power Station.
We use groundwater in the process, and we will analyze the water quality regularly to check for radioactive contamination and inform you here.
We will investigate the analysis twice a month for the time being for three months.
The analysis result of water sampling on 3/24 is
Analysis item Radioactivity concentration (Bq / L) Detection limit concentration (Bq / L)
1) Iodine-131 ND 7.45
2) Cesium-134 ND 4.49
3) Cesium-137 ND 6.12
* ND is below the lower limit of detection.
