Abstract: The article explores the process of obtaining modified sulfur concrete based on local raw materials and the study of radionuclides of sulfur concrete and Portland cement. The novelty of the work was determined by the amount of radionuclides Ra-226, Th-232, K-40 in sulfur concrete and Portland cement. Considering the advantage and convenience of sulfur concrete, it was analyzed on a gamma spectrometer. Accordingly, the test conditions are: T-22°C, humidity -63%, illumination-300 lux, specific activity Bq /kg. According to SanPiN 0193-06, they are used in construction at a level of less than 350 Bq / kg. In the analysis of sulfur concrete, its radionuclides averaged 127 Bq /kg. Sulfur concrete contains modifier-26%, sand-54%, ash (ash) -16% and various metal oxides -4%. Additives and fillers added to sulfur concrete, ie radionuclides in sand and gravel were analyzed using gamma spectrometry.
Key words: Sulfur, modified sulfur, crotonic aldehyde, modification, gamma spectrometer, sulfur concrete.
