Abstract

To measure the flux density and fluence of thermal neutrons, a method, in which is proposed to use single-crystal silicon as a thermal neutron detector, has been developed. The advantage of this method is that it does not require special measuring equipment. To measure the absolute values of the thermal neutron fluence, it is proposed to irradiate silicon with and without a cadmium screen, as is done in the activation method. The results of the work showed that its accuracy of measuring the thermal neutron flux is not inferior to traditional activation methods, but unlike them, the information on the detector can be stored indefinitely, since the electrophysical parameters of silicon change during irradiation, which do not depend on the induced activity and half-life material.
