It is necessary to evaluate tritium concentration in flatfish after discharge of treated water from the Fukushima Daiichi Nuclear Power Plant and to clarify the actual tritium accumulation in flatfish in the real environment. In this study, we analyzed two types of tritium (tissue free water tritium (TFWT) and organically bound tritium (OBT)) in flatfish in the Fukushima coast before and after discharge of treated water, and compared them with tritium in seawater around flatfish to clarify the actual tritium accumulation in flatfish due to water discharge.
