Research Abstract

We developed a two dimensional differential neutron calibration method using a time of flight (TOF) technique and an intense thermal neutron beam from a research reactor for precise calibration of neutron dosimeters. A thermal neutron beam was obtained from a research reactor "JRR-3M" in the present study. After characteristics of the thermal neutron beam were experimentally evaluated, the calibration method was experimentally demonstrated for a 3He spherical proportional counter and a electric personal dosimeter. The responses of the detectors were successfully obtained as a function of neutron energy in the thermal neutron region..
