[en] The possibility of the rapid analysis of slags by neutron activation and x-ray radiometric methods is studied. It is necessary to consider these methods in combination since each of them separately does not allow one to determine that minimum of elements required which is of interest to technologists. The analysis of standard slags with respect to the presence of aluminium and silicon has been conducted by the neutron activation method under the following conditions: irradiation for 2 min., transportation and aging for 10 sec., the measurement of the activity of the silicon standard for 1.5 min., the measurement of the slag activity (1 min. after the irradiation) for 2 min. The total time of analysis (without the time of sample preparation) equals 5 min. Under the above conditions of determination for fluence 5x10⁹ neutr./sec the sensitivity of the analysis for the presence of silicon and aluminium is equal to 120 000 and 30 000 pulse/g, respectively. The rapid determination of iron and calcium contents in slags has been conducted by means of a two-channel x-ray radiometric analyzer. When the iron contents is determined, the samples under study are irradiated by the ¹⁰⁹Cd radioisotope source in the case of calcium determination the source being ⁵⁵Fe. The calcium contents has been determined with an error of approximately 1 rel.%
