Abstract

This paper discusses the spatiotemporal variation in atmospheric tritiated water (HTO) concentration near the Fukushima Daiichi Nuclear Power Plant (FDNPP) from 2019 to 2021. The monthly HTO concentrations varied seasonally from below the detection limit to 280.4 mBq m^{− 3}. The HTO concentrations were decreased with the distance from the FDNPP to the pre-accident level at 5 km. The concentration was related to northeasterly wind, suggesting a potential atmospheric release of HTO vapor from the FDNPP. Our results highlight the need for detailed studies to comprehend HTO transport in atmospheric environments.
