The possibility of operative control of basic iron content in mining rock, transported by conveyer belt, and its weight, using microprocessor systems, used gamma-ray emission of source on the base of ²⁴¹Am has been shown. During comparing the results of Fe_basic content defining, obtained with microprocessor system of NAKS-PK and chemical analysis, it has been determined that mean square deviation of measures is equal to 2.45.
