Abstract
This paper describes the development and standardization of simple neutron reference calibration fields. These fields have been arranged for calibration of neutron detectors particularly used for radiation control and environmental measurements, having four different neutron spectra formed by a 252Cf source with or without moderators of iron, carbon or polyethylene. These calibration fields are independent of room-scattered neutrons, since they use only direct neutron components which are obtained by subtracting the results with shadow blocks from the results without those. The absolute energy spectra and dose equivalents of direct neutrons and room-scattered neutrons, and the effect of a shadow shield have been calculated by the one-dimensional ANISN-W, two-dimensional DOT-3.5 discrete ordinates codes and the three-dimensional MORSE-CG Monte Carlo code, for these four fields.
