On registration of high intensity radiation

The influence of the statistics of temporary passage of the detected radiation pulses on the registered spectrum and intensity is investigated. Derived are the formulae, describing the registered amplitude spectrum for the first and second type recorders of simple summation with the arbitrary dependence of the dead time upon the incoming pulse amplitude and with the arbitrary amplitude spectrum of the incoming radiation flux. The possibility of the solution of the reverse tast - the spectrum restoration of the incoming flux according to the registered one in the device of the above type is discussed
