Abstract

Proton induced gamma emission (PlGE) method has been developed at the Accelerator Laboratory of Atomic EnergyCentre, Dhaka (AECD) for analyzing low Z elements in the range of 3 to 15. With a view to exploiting the potential of PIGE technique as a tool for practical applications, attempts have been made to find the experimental evidence for its capability and scope. Gamma ray yields from PIGE experiments and the sensitivity for some low Z elements such as lithium, fluorine, boron, sodium, magnesium, silicon, beryllium and oxygen have been measured at proton energy 2.9 MeV in order to assess its capability and to identify its limits. The PIGE method has also been utilized for isotopic speciation of different isotopes of magnesium present in local vegetables to assess its suitability for the analysis of isotopes of different elements present in samples of interest. Present study demonstrates the characteristics of the PIGE method that establish it as a reliable and useful technique capable of rendering analytical services especially in the health and environmental sectors.
