The Impact

The article presents the results of the development of the scintillation gamma spectrometers, based on NaI(Tl), LaBr3 or SrI2(Eu) scintillators, intended for aerosol monitoring over a wide temperature range. The stabilization of the characteristics is provided by applying various stabilization methods of the spectrometric chain. The estimation of the impact of those methods on the stability of the characteristics of the developed radiation spectrometer is provided.

The article describes the modeling results of drainage water in the tailing dumps of Komsomolsky tin ore district in the temperature range from-10 to +45 °C. Eh-pH parameters of technogenic mineral systems for different ratios of host rock - sulfides (95:5, 90:10, 80:20 and 60:40) in the tailings were determined. The process of hypergene mineral crystallization from micropore solutions was researched, its qualitative and quantitative ion composition was established and its impact on surface and ground water of the district was showed.
