摘要：
Radioactivity (Ra-226, Cs-137, Th-232 and K-40) levels in peloids from some Cuban spas (San Diego, Elguea, Santa Lucia and Cajio) have been studied. The radionuclide concentration ranges in peloids on Bq kg(-1) dry weight varied as follows: Ra-226 = 6-1800, Cs-137 = < 1.6-5.0, Th-232 = 6-38 and K-40 = 47-365, and are in the same order of concentrations reported for therapeutic peloids used worldwide. The estimated annual equivalent dose in Ra-226-enriched peloids, considering the short exposition times associated with the usual therapeutic practices in Cuban spas, is well below accepted equivalent dose values to the skin for members of the public. Therefore, radioactivity levels present in peloids from the studied Cuban spas are not significant and do not represent an impediment for its use with therapeutic purposes.
