Recovery efficiency of 137Cs in seawater samples with different volumes of 40, 50, 60, 80 and 100 liters using co-precipitation method by ferrocyanide compounds has been determined. 134Cs nuclide was used as a tracer to determine recovery efficiency. The results showed that the recovery efficiency of 134Cs ranged from 92.62% to 99.26% with mean value of (95.22 ± 2.61)% for different sample volumes. Average recovery efficiency for samples with a volume of 50 liters was (95.70 ± 2.50)% and uncertainty when determining 137Cs in seawater samples were still less than 20%. Therefore, reducing the volume of sample to 50 liters still ensures reliability when determining 137Cs in seawater samples by co-precipitation method, thereby reducing the chemical and time when analyze a large number of samples. |
