Radiation Measurement Results of 74 items in February 2013
※The analytical software we used for radioactivity measurement between November 2011 and March 2013 wasolder than the one we use currently, therefore, the both values for measured results and minimum limit ofdetection during this period may differ comparing the present measured values. Please refer those values
as an indication for radiation dose at the time of the Daiichi Fukushima nuclear accident.
When samples include natural radionuclides we can't deny the possibility of their radiation value
counted together in our results.
The list below only shows the measurement results of the samples brought in.
Radioactive contamination level may differ according to sampling points even within the same address.
