Opis:
The paper presents the balance of energy consumption for domestic heating in Opole and Silesian Voivodship (Poland), divided into various media. The report was based on an analysis of approximately 250 documents containing low-carbon economy plans for individual municipalities (gminas). The authors compared the current situation in these voivodships and their districts with the structure of the heating system in Poland as a whole, based on data from the Central Statistical Office of Poland. The data demonstrate that the use of coal-based energy media has not changed significantly over the years and around 55-60% of households with individual heating systems use this type of media. A much more favourable trend is found in large urban centres, where there is a high proportion of district heating. The most common of the lower-emitting fuels (LPG, natural gas, electricity, heat pumps) is natural gas, and the share of the remaining sources within this group are barely significant.

Opis:
In several coal mines in the Upper Silesian Coal Basin (USCB), in Poland, radium removal from mine water was necessary in order to mitigate the negative results of radium release with mine effluents. The most efficient method of radium removal was based on the application of barium chloride, implemented in full technical scale in two Polish collieries. Removal efficiency exceeding 95% of the initial activity was achieved. The technology was implemented in full technical scale in two collieries. The problem was that barium chloride is dangerous to health and moreover continuous use of the powdered chemical was required to achieve good results. Therefore, the possible application of zeolite for radium removal was tested in laboratory experiments. This passive technique would be less hazardous for miners and would not require full-time supervision meaning it would enable a reduction in workload. The main goal of the investigations described in this paper was to check the capability of zeolites to remove natural radionuclides from mine waters and compare the removal efficiency of radium isotopes with the results obtained from the application of barium chloride solution for the same purpose.
