Assessment of Radioecological Safety of Coals and Ash and Slag Waste

TRUDY UNIVERSITETA
The analysis of statistical data on the natural radioactivity of coals from various deposits was carried out. It was noted that natural radioactivity is mainly caused by the presence of radioactive nuclides of uranium, thorium and potassium in coals, the concentration of which varies significantly. Fossil coals of Kazakhstan are generally characterized
