Response functions of NE213 liquid organic scintillator have been measured to develop a dose assessment method for high-energy neutrons. Spallation reactions by 800 MeV/u Si ions and 400 MeV/u C ions incident into thick carbon targets were utilized for the production of high-energy neutrons. Kinetic energies of neutrons were determined by the time-of-flight (TOF) method. -ray and charged particle events were eliminated from experimental data in off-line analysis. The measured response functions were used for validation of the simulation by the SCINFUL-QMD code, which is utilized for calculation of the G-function that converts the scintillator response to neutron dose. It was found from the results that SCINFUL-QMD has a good ability to reproduce the response functions.
