In this study, the activity concentrations of 210Po and 210Pb were determined in different types of bivalve molluscs sampled during the period of May 2014-June 2015 along the Andalusian littoral. Radioactivity concentrations of 210Po were determined through alpha-particle spectrometry using 209Po as an internal tracer. Radioactivity concentrations of 210Pb were determined through low-level gamma-ray spectrometry. The activity concentrations of 210Po and 210Pb varied between 40 ± 2 and 515 ± 9 Bq kg-1 dry weight (d.w.), and ND (lower than limit of detection) and 73 ± 10 Bq kg-1 d.w., respectively. The committed effective dose to humans was calculated to range from 39 to 477 μSv year-1. Radioactivity and dose levels were compared with previous studies from other countries.
