Determination Of 137Cs Content In The Soil At Several Places In South Sumatra Province

Analysis of 137Cs in the soil samples have been conducted at several places in south Sumatera Province such as Palembang, Kayu Agung, Prabumulih, Muara Enim, Lahat, Lubuk Linggau, and Sekayu. The samples were collected from the different depth, i.e. 0-5 cm and 5-20 cm from the surface. Measurement of 137Cs was done by using the gamma spectrometer with the HP-Ge detector. The results of measurement showed that the 137Cs concentration was within the range of undetectable to (1.99 ± 0.36) Bq/kg with an average value of (1.64 ± 0.35) Bq/kg for the depth of 0-5 cm and within the range of undectable to (1.50 ± 0.33) Bq/kg with an average value of (0.91 ± 0.30) Bq/kg for the depth of 5-20 cm.
