Lead-210 Content in Foodstuff and its Dietary Intake in Japan

Concentration of ^<210>Pb in various kinds of Japanese foodstuff was measured in order to investigate the relationship between the intake level of the nuclide and the dietary habit in this country. Dietary intake of this naturally-occurring radionuclide was estimated to be around 17 pCi per day by use of the statistical data on the daily consumption of individual foodstuff. This dietary intake level of ^<210>Pb seems to be appreciably high relative to that in European countries. Inter-regional difference of dietary intake level which was found in the present investigation may be ascribable mainly to the local variation of the concentration in vegetables. The largest contributor to the total dietary intake of ^<210>Pb would be sea foods which have relatively high concentration of the nuclide and are being consumed to a considerable extent in this country. This is the most characteristic feature of ^<210>Pb intake in Japan due to the traditional dietary habit.
