the neutron dose can be estimated by measuring radioactivity of 24Na in blood of the patients.In this work
NaCl solution as simulated blood was irradiated by a 252Cf neutron source
and measured by a low background γ-ray measurement system.The 24Na activity was measured at different source-sample distances for different irradiation hours.The 24Na activity after decay correction decreases exponentially with increasing distance
