Abstract

Abstract Concentrations of 210Po in fish and shellfish, mostly collected from southern region of Japan were analyzed. Values ranged from 0.2 to 229 Bq/kg fresh weight and higher concentrations were observed in samples analyzed with viscera. Intake of 210Po through fish and shellfish was evaluated at different Japanese cities based on statistical consumption data. Phytoplankton, Heterosigma akashiwo was collected during a harmful algal bloom and 210Po was analyzed. The phytoplankton occupied only 4.4% of 210Po in seawater and a large fraction of 210Po was observed in the particulate form.
