title: Spatial sensitivity measurements of a prompt gamma IVNAA facility.
abstract: A technique has been developed for measuring the spatial sensitivity of a prompt gamma in vivo neutron activation analysis facility as used for determining total body nitrogen (i.e. protein). A water filled perspex phantom was used to simulate a patient. Relative spatial sensitivity of the system was measured at various positions in the tank by observing the prompt gamma rays from thermal neutron capture in the 35Cl of a carbon tetrachloride sample contained in a small glass phial.
