REFERENCE FIELDS SUPERPOSITION METHOD FOR DOSIMETRIC APPARATUS CALIBRATION TO OPERATE WITHIN NEUTRON RADIATION-FIELDS

It has been proposed to calibrate some single neutron dosimetric detec tors in several reference fields with neutron spectra whose linear com bination with some weighting coefficients approximates the spectrum in the real measurement place. The corresponding linear combination of t he readings for the detectors in these reference fields with the same weighting coefficients is used as the detector reading in a single ref erence field. The efficiency of this calibration method with eight rea l reference fields has been investigated with the help of computer sim ulation. It has been shown that this method allows one to calibrate do simetric detectors more correctly than commonly used techniques.
