On August 24, 2023, the discharge of radioactive contaminated water from
Fukushima Daiichi Nuclear Power Station (FDNPS) began.

We collected seawater samples around FDNPS in December of that year and
analyzed the concentration of radioactive cesium-137 to compare with the
data before the release.

Radioactive cesium concentration analysis was performed using the
AMP(Ammonium molybdophosphate) method in cooperation with CNIC.
