Description
Изобретение относитс к анализу состава вещества рентгенорадиометрическим методом и может быть исполь . зовано на горнообогатительных металлургических , химических и других промышленных предпри ти х.This invention relates to the analysis of the composition of a substance by the X-ray radiometric method and can be used. It is called for ore-dressing metallurgical, chemical and other industrial enterprises.
Известны способы градуировки при рентгенорадиометрическом анализе с нефиксированным рассто нием датчикпроба , основанные на измерении потоков квантов характеристического и рассе нного излучений.Calibration methods for X-ray radiometric analysis with non-fixed sensor probe distance are known, based on measuring the fluxes of quanta of the characteristic and scattered radiations.
Наиболее близким по технической сущности к предложенному вл етс способ градуировки при рентгенорадиометрическом анализе по- методу стандарта-фона , иключаюпщй изготовление стандартных образцов с известным содержанием определ емого элемента.The closest in technical essence to the proposed method is the method of calibration for X-ray radiometric analysis using the standard-background method, and includes the manufacture of standard samples with a known content of the element being determined.
измерение на этих образцах потоков квантов характеристического излучени определ емого; элемента и рассе 4 нного излучени и нахождение завиСО симости между содержанием определ емого элемента и измеренными значени 00 0 ми.measuring the fluxes of quanta of the characteristic radiation to be detected on these samples; the element and the scattering of the radiation and the finding of a dependence between the content of the element being detected and the measured values of 00 0.
Недостатком известного способа вл етс низка точность градуировки, обусловленна тем, что из-за различной энергии ха1 актеристического и рассе нного излучений они по-разному ослабл ютс и рассеиваютс слоем воздуха между пробой и датчиком. В результате при изменении рассто ни между объектом измерени и датчиком (например, при покусковой сепарации или при сортировке руды в вагонетках ) отношение потоков характеристиThe disadvantage of this method is the low precision of calibration, due to the fact that, due to the different energies of random and scattered radiations, they are attenuated in different ways and dispersed by a layer of air between the sample and the sensor. As a result, when the distance between the object of measurement and the sensor changes (for example, when hitting separation or when sorting ore in trolleys), the flow ratio
