For removal of radium from saline waters in Upper Silesian mines, several methods purification have been developed. The most efficient one is based on application barium chloride, which was implemented full technical scale two Polish coal mines years ago. Very good results achieved-the efficiency exceeding 95% the initial activity. Another possibility for different ions salty and brines zeolites. We found that technique as a very promising method not only isotopes mine but also other...
The Upper Silesian urban-industrial agglomeration is one of the most industrialized areas in Europe. intense industrialization should be attributed mostly to presence coal and other minerals deposits its extraction. Mining hard mines comprise approximately 25% total catchment area watercourses Coal Basin, including river basin Oder River Little Vistula River. mining, scope depth, duration mining works, extraction systems being used volume drainage fundamentally affect conditions groundwater...
The Upper Silesian Coal Basin (USCB) in Poland is an excellent example of area affected by increased migration radon and penetration into buildings. This occurs due to changes the geological environment caused exploitation mineral resources. Studies conducted past showed that levels emission, depend a large extent on structure subsurface layers. Mining-induced rock body are one main factors influencing radon's ability migrate. Some investigations were made near shafts which closed many years...
In the last few years in Poland consumption of natural bottled mineral and spring waters is growing. Waters are taken from surface springs or shallow wells. On other hand, highly mineralized used medical treatment extracted deep-bored Due to origin water, it may contain naturally occurring radioactive isotopes. The most important radionuclides 226Ra, 228Ra, 210Pb 210Po as they could contribute effective dose greatest degree due by people. frame work, radium isotopes were determined which...
The highly mineralised formation waters in the coal mines of Poland's Upper Silesian Coal Basin contain natural radioactive nuclides, mostly radium. 226Ra concentration groundwater that flows into underground mine workings reaches 390 Bq/L, and is sometimes exceeded by 228Ra concentration. radium-bearing water also barium ions, which enables coprecipitation barium-radium sulphate. Another type contains sulphate ions instead barium; this case, radium transported to settling ponds downstream....
The objective of this work was to perform a series measurements radon and thoron exhalation in the underground workings an experimental coal mine. In years 2012–2015, experiments on gasification were carried out mine, which caused, among other effects, damage rock mass. Afterward, periodic increases concentration potential alpha energy (PAEC) decay products air found, could pose hazard miners. question posed whether experiment resulted increased migration thoron. If so, did it increase...
In the formation waters, occurring in coal mines Upper Silesian Coal Basin, Poland different pollutants are present which may cause damages to environment, among them radium isotopes. several collieries removal from mine water was necessary mitigate negative results of release with effluents. The most efficient method is based on application barium chloride, implemented full technical scale two Polish collieries. Another possibility isotopes salty waters an zeolites. this paper, a review...
The radiation risk due to the exposure natural radionuclides, especially short-lived radon progeny, is a component of hazard, common in environment and working environment. In Polish mining industry caused by radionuclides hazard. Radon air radium present underground brines are sources hazards. Sediments precipitated out from such waters with enhanced content may cause increase external gamma dose rate as well internal contamination accidental ingestion or inhalation.
In several coal mines in the Upper Silesian Coal Basin (USCB), Poland, radium removal from mine water was necessary order to mitigate negative results of release with effluents. The most efficient method based on application barium chloride, implemented full technical scale two Polish collieries. Removal efficiency exceeding 95% initial activity achieved. technology problem that chloride is dangerous health and moreover continuous use powdered chemical required achieve good results....
Abstract The new basic safety standards (BSS) Directive 2013/59/Euratom [1] puts EU member states under an obligation to establish, amongst others, national radon action plans. In order address the issue of long-term risks from exposures, it is important identify areas where elevated levels can be expected. One types affected by increased migration and penetration into buildings are in which industrial activity, for example, exploitation mineral resources, causes changes geological...
Radon activity concentrations measurements in some Jurassic caves of Poland are presented. The aim is to estimate the radiation doses casual visitors, cavers and guides show caves. levels were measured using passive integrating monitors based on LR-115 detectors (for 2 months exposures) Lucas cells grab sampling). range between 10 2410 Bq m–3 for long-term 50 10150 sampling. annual effective dose estimates from 0.002 15.5 mSv. results that, specific conditions, may be higher than miners...
The article presents the results of radon research, carried out in area mining commune Upper Silesian Coal Basin (USCB), Poland. Past investigations 1990s on concentrations buildings, located within area, showed that indoor measured affected by were higher than buildings outside area. Currently, all underground hard coal mines boundaries observed have been closed. In 2020, after closure last active mine, measurements started again. current compared with archival from 1990s. It was found...
Mine closure is the natural final stage of mining activity. The process financing mine liquidation complex and expensive. many years conducted hard coal extraction affect surface height differences. Analyses shifts in hydrogeological conditions water hazard states plants led to legal regulation adaptations, primarily terms documentation preparation, made it necessary conduct work concerning new options for assessment prevention. Current subjects particular interest include terrain morphology...
One of the most serious problems occurring during coal extraction in Upper Silesia Poland is caused by waters with very high salinity. These often contain also concentrations natural radionuclides, mainly 226Ra from uranium series and 228Ra thorium series. At least 70% total amount radium carried this remains nowadays underground galleries as radioactive deposits. But, period extensive up to 225 MBq 400 were released daily into surface along other mine effluents. As a result discharge...
Saline waters from underground coal mines in Poland often contain natural radioactive isotopes, mainly 226Ra the uranium decay series and 228Ra thorium series. More than 70% of total amount radium remains as deposits due to spontaneous co-precipitation or water treatment technologies, but several tens MBq even higher activity are released daily into rivers along with other mine effluents all Polish mines. Mine can have a severe impact on environment, its salinity. Additionally high levels...
