Abstract

Изобретение относится к физическим способам анализа веществ. Способ двухзондового исследования, основанный на регистрации рассеянного -излучения двумя зондами, отличающийся тем, что на стандартных образцах вещества со средними Z измеряют интенсивности рассеянного -излучения от энергии при малой L1 и большой L2 длине зонда, находят критические энергии E1 и E2, соответствующие максимуму в спектре рассеянного -излучения, в области выше E1 находят интервал E1, при котором достигается минимальная чувствительность к Z, в области ниже E2 находят интервал E2, при котором достигается максимальная чувствительность к Z, измеряют при малой длине L1 интенсивность -излучения N1 в найденном интервале E1, при большой длине L2 интенсивность -излучения N2 в найденном интервале E2, а плотность определяют по интенсивности N1, a Z - по отношению N2/N1. Технический результат изобретения состоит в повышении чувствительности и расширении сферы применения способа за счет нахождения при L1 и L2 соответственно интервалов E1 и E2, при которых измеряются интенсивности N1 и N2.The invention relates to physical methods for the analysis of substances. The method of two-probe research, based on the registration of scattered γ-radiation with two probes, characterized in that the intensities of the scattered γ-radiation from the energy are measured on standard samples of material with average Z for small L1 and large L2 probe lengths, and the critical energies E1 and E2 corresponding to a maximum in spectrum of scattered radiation, in the region above E1 find the interval E1 at which the minimum sensitivity to Z is achieved, in the region below E2 find the interval E2 at which the maximum sensitivity to Z is achieved, measure at a short length L1 the intensity of the γ-radiation N1 in the found interval E1 , for a large length L2, the intensity of γ-radiation N2 in the found interval E2, and the density is determined from the intensity N1, and Z - from the ratio N2 / N1. The technical result of the invention consists in increasing the sensitivity and expanding the scope of the method by finding at L1 and L2, respectively, the intervals E1 and E2, at which the intensities N1 and N2 are measured.
