1. Рентгеновский способ обнаружения вещества по значению атомного номера, включающий просвечивание контролируемого объекта рентгеновским излучением и регистрацию прошедшего через объект излучения в двух спектральных областям с различной эффективной энергией, отличающийся тем, что среди зарегистрированных сигналов выделяют сигналы, пропорциональные интенсивности излучения, прошедшего через "фоновое" вещество и совокупность "фонового" и идентифицируемого веществ, затем по значениям сигналов поглощения излучения "фоновым" веществом выбирают градуировочную зависимость сигнала большей эффективной энергии от сигнала меньшей эффективной энергии излучения, прошедшего через совокупность калибровочного "фонового" вещества, эквивалентного по значениям сигналов "фоновому" веществу объекта, и подлежащего обнаружению вещества переменной толщины, затем сравнивают значения сигналов градуировочной зависимости со значениями выделенных зарегистрированным сигналов поглощения излучения совокупностью "фонового" и идентифицируемого веществ, и при наличии в градуировочной зависимости сигналов, значения которых равны значениям зарегистрированных сигналов, принимают решение о равенстве атомных номеров идентифицируемого и подлежащего обнаружению веществ.1. An X-ray method for detecting a substance by the value of its atomic number, including x-raying of a controlled object with x-ray radiation and recording of radiation transmitted through the object in two spectral regions with different effective energies, characterized in that among the recorded signals, signals are proportional to the intensity of the radiation transmitted through the "background “substance and a combination of“ background ”and identifiable substances, then by the values of the radiation absorption signals by the“ background “substance in the calibration dependence of the signal of higher effective energy is selected from the signal of lower effective radiation energy that has passed through the totality of the calibration “background” substance, equivalent in value to the signals of the “background” substance of the object, and the substance of variable thickness to be detected, then the values of the calibration dependence signals are compared with the values highlighted by the registered radiation absorption signals by the combination of "background" and identifiable substances, and if there is a calibration curve signal values, the values of which are equal to the values of the registered signals, decide on the equality of the atomic numbers of the identified and detectable substances. 2. Способ по п. 1, отличающийся тем, что градуировочные зависимости определяют заранее при тех же параметрах излучателя и приемника рентгеновской установки, что и при просвечивании контролируемого объекта. 2. The method according to p. 1, characterized in that the calibration dependencies are determined in advance with the same parameters of the emitter and receiver of the x-ray unit, as with the transmission of the controlled object.
