The aim of these investigations was to improve gamma dose determination with Geiger-Muller counters. The required values of the responses of the detector for neutrons and gamma rays were taken from the literature. The time discrimination of the signals, a method used to discriminate neutron and gamma radiation in neutron response measurements, makes possible the determination of the gamma doses caused by (n,n'γ) and (n,γ) processes. The experiments were performed with an accelerator in pulse mode. The radiation time was selected to be as small as possible to reduce the build-up of thermal neutrons in the phantom during irradiation. The pause time was chosen to allow the decrease of thermal neutrons produced after moderation. The different gamma spectra emitted by (n,n'γ) and (n,γ) processes were considered in calculating the gamma dose. In the centre of the trunk of the water phantom, the H(γ(n,n'γ))/H(γ(n,γ)) ratio is given by 2.0 ± 0.2.
