The work is devoted to the experimental substantiation of the need to take into account the dead time of the spectrometer when working with high input counting rate in the problems of analytical control of the elemental composition of metals and alloys. Using samples of steel, copper-nickel alloys, zirconium alloys, and zinc coatings on steel as an example, it is shown that taking into account the dead time of the spectrometer when working with high input counting rate in tasks of analytical control of the elemental composition of metals and alloys critically affects the accuracy of the measurement results. The error in determining the dead time contributes to the resulting value of the uncertainty of the intensities of the analytical lines. The principles of accounting for the dead time also apply to gamma-spectrometers, the use of which is also in demand in analytical control tasks
