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.
