Radiation properties of industrial waste

The problem of obtaining environmentally safe materials is especially important when using waste products that concentrate in themselves natural radionuclides (NR), which pose a danger to human health and the environment. Similar concentrators of NR include waste from the coal mining and power engineering industries. The aim of the work was to determine the radionuclide composition of fractions of coal mining waste and fuel ash-slag and their compliance with the radiation safety standards of Ukraine and international radiological indicators. NR: 226Ra, 232Th, and 40K were found in the composition of fuel ash-slags and slag from coal mining. The content of radionuclides varies by fraction of the waste. The main contribution to the value of the effective specific activity of waste is made by 226Ra and 232Th. The largest variation in specific activities by fractions of fuel ash-slags and dump rock of coal mining is characteristic of 226Ra. All investigated wastes belong to the I class of radiation hazard (Bq/kg) and can be used in construction without restrictions. According to international radiological indicators, the value of the activity utilization index is exceeded for almost all of the investigated wastes. The gamma radiation of the burnt dump rocks of the Olkhovatskaya mine (fraction
