dc.description.abstract	DET-12 is a device to measure delayed neutrons from fissions in fissionable material samples which were activated in the primary neutron flux from D-T or D-D reactions in hot plasma of big fusion devices (tokamaks, stellarators). In the paper, a method is outlined how to interpret the registered time decay of delayed neutrons in order to obtain information on intensity of the primary neutron flux. The method combines a restoration of the decay function (multi-exponential) from the data stored in a multiscaler regime and a Monte Carlo calculation of a basic approximation of the neutron energy spectrum.	pl_PL.UTF-8
