摘要：

Natural (U-238 and Th-232 series, K-40) and artificial (Cs-137) radioactivity levels in the sediments of Algiers bay were measured using gamma-ray spectrometry. Concentrations (Bq kg(-1), dry weight) have been observed to range from 10.8 to 25.0 for U-238, from 6.5 to 31.7 for Th-232, from 55.9 to 607.4 for K-40 and from 0.95 to 9.5 for Cs-137. These values are discussed in terms of the facies type of the sea bottom. (C) 1997 Elsevier Science Ltd.
