Measurement of Radionuclides in Agricultural Soil at Mandalay Region

This study aims at investigating the environmental impact of the use of phosphate fertilizers in environmental compartments, namely soils, by physical and nuclear techniques. The investigation focused on radionuclides present in fertilizers and cultivated soils, and their decay in time. The radionuclides, 228Th, 228Ra, 232Th and 40K were detected in soil samples treated with GTSP 46% and SSP 16% fertilizers. It is found that the decrease of radionuclides content in soil samples with time was due to the percolation of radionuclides along the soil profile
