Development of In Vivo Prompt Gamma Activation Analysis Using the Filtered Neutron Beam at the Dalat Reactor

Abstract

The development of a method for in vivo measurement of some elemental concentrations in organs making use of prompt gamma activation analysis with the filtered neutron beam at the Dalat reactor is being carried out. In this paper we present primary results in research and development of an IVPGNAA facility at the Dalat reactor. Beside the description of experimental set-up, they consist of determination of thermal neutron flux distribution in phantom, and the evaluation of the detection limit and analytical sensitivity for Cd in the kidney and the liver. Discussions are given to improve the IVPGNAA facility in the future.
