Abstract:
To investigate the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident's radiological effect on marine ecosystem, ash samples of squids from the western Pacific Ocean were collected in May 2014 and measured using an underground gamma-ray spectrometer in the underground laboratory JinPing. Low levels of 108mAg, 110mAg, 134Cs and 137Cs were detected, which indicates that the influence of the FDNPP accident on marine ecosystem is lasting but decreasing.
