Abstract

The elemental concentration of arable soil samples collected from different areas of Savar were measured by proton induced gamma emission (PIGE) analytical technique. The samples were  irradiated by the proton beam obtained from the 3MV Van de Graaff accelerator at the AECD (Atomic Energy Centre, Dhaka). The characteristic gamma emitted from the exited nuclei of the irradiated samples were detected by a HPGe spectrometer system. The following elements were detected Na, B, Mg, Sc, Li, Cl, F, and P and their concentrations were obtained by comparing the PIGE gamma yields with that of the standards such as USGS geological standards, AGV-1 and Soil-7. Finally the results of the experiments were discussed in the light of elemental deficiencies or the toxicities in the arable soil of Savar and the likely impact they may have on the growth and yield of specific vegetables grown in the area.
