- Samples are collected and analyzed everyday using a germanium semiconductor detector.
- It is known that rainfall may increase values.
- The number of significant digits of values is set as 2 in order to be consistent with that of the Japanese government.
- Please see here about the principle behind “ND (Not Detectable)”.
- A unit of values is Bq/m2, identical to MBq/km2.
Please see the pages for each year for data from previous surveys
