Contamination Levels of Radioactive Cesium in Fat Greenling Caught at the Main Port of the Fukushima Dai-ichi Nuclear Power Plant

Year: 2015

Type: book-chapter

Abstract: Levels of radioactive cesium (radiocesium, 134 Cs + 137 Cs) detected in fish caught at the Fukushima Dai-ichi Nuclear Power Plant (FNPP) Port are summarized. The mean concentration of radiocesium in three fish species (fat greenling, Japanese rockfish, and spotbelly rockfish) was significantly different from that in other fish species studied (brown hakeling, black rockfish, Japanese black porgy, olive flounder, marbled flounder). The levels of radiocesium in fat greenling decreased gradually from 100 kBq/kg-wet in 2013 to several kBq/kg-wet in 2014. A migration of fat greenling into the FNPP Port was assumed to explain the fact that fish containing low radiocesium levels were caught at the port. A low but significant correlation between the total length of the fish and the radiocesium concentration in the muscles was observed in fat greenling caught at the FNPP Port.
