International Journal of Low Radiation (IJLR), Vol. 9, No. 4, 2014

Abstract: ²¹⁰Pb is widely distributed in the marine environment. The aim of this research, therefore, was to determine ²¹⁰Pb concentrations in marine salt consumed by the population of Recife and calculate the ingestion dose of ²¹⁰Pb due to marine salt consumption. The ion exchange resin method was used. The concentration of ²¹⁰Pb varied from 4 to 365 Bq kg⁻¹ in fresh weight. The estimated ingestion dose of ²¹⁰Pb due to consumption of marine salt in the population of Recife was 1.2 Sv, at least three orders of magnitude above the maximum recommended level.
