 note = {Monitoring of radiocesium activity concentration in stream water, river sediment and riverbank soil, and measurement of air dose rate were carried out in the forest catchments in 2018, and then external exposure doses of workers were measured using the dosimenter (DOSEe nano and D-Shuttle) and GPS. The external exposure doses of workers were calculated with based on the results of measurement of radiation dose rates. The observed ranges of air dose rate were 0.5~2.2 uSv/hr around Maeda river area in Ishikuma (Futaba town) and, 3.7~4.8 uSv/hr around Saruta river in Kajiyadaira and 0.5~2.2 uSv/hr in Sarutahashi (Namie town), respectively. Estimated external exposure doses due to work in 3 hours around Kajiyadaira were 2.4~3.0 Sv/hr (DOSEe nano) and 1.7~2.4 Sv/hr (D-Shuttle). These may be caused by the difference in accumulation time of the dosimeter, as the accumulation time of DOSEe nano and D-Shuttle are 1 minute and 1 hour, respectively. The dose rates calculated from the dosimeter installed on the dashboard of the car for reference were similar to the low values of worker. In this presentation, we report about the evaluation of external external dose and the relationship with the radiocesium activity concentrations around the forest catchments in 2018., 第5回福島大学環境放射能研究所成果報告会},
