The invention relates to means of measuring equipment for measurement and registration of power spectrum and power of exposition dose of radioactive radiation. Scintillation spectrometer includes scintillator, photoelectric multiplier in pulse mode of operation, adders, two-input comparison elements, resistive divider, registers and amplitude analyzer output of which is output of the whole system, and additional block of combination adders inputs of which are connected to outputs of registers to which before cycle of measurements calculated before coefficients of compensation of power dependence of sensitivity of scintillator are entered, and permit for re-writing of number from register to respective adder comes to decision-making input of register from output of adder by module 2, its inputs are connected to outputs of two neighboring two-input comparison elements, to first combined inputs of which measured signal comes, its amplitude includes information on number of sub-range of measurement, and to the second input–support voltage from resistive divider. The invention provides measurement of power spectrum and power of exposition doze of ionizing radiation in real time with simultaneous decrease of error of measurements. |
