(210)Po in the daily diet in Korea was analyzed and the ingestion dose from an intake of (210)Po was estimated by considering the dietary habit of a Korean person. The (210)Po concentrations of a leafy vegetable (0.36 Bq center dot kg(-1) for lettuce) in the terrestrial food were higher than those of grain, whereas Chinese cabbage had a lesser (210)Po concentration (0.019 Bq center dot kg(-1)). The (210)Po concentration of the animal product was similar to those detected in the grain and vegetable. The (210)Po concentrations in the shell and crustaceous were high from 19.1 to 33.0 Bq center dot kg(-1), however, its value fell in the overall range of the reported values. The effective dose from (210)Po for an adult from the Korean population was about 269.4 mu Sv center dot y(-1). Nearly 80% of the ingestion dose from the intake of (210)Po was attributed to the consumption of seafood. It suggests that the marine food ingestion is a critical pathway for natural (210)Po to the Korean population.
