[en] Uranium concentration and the A²³⁴U/A²³⁸U activity ratio have been measured in 50 samples of waters from carboniferous formations of the South Upper Silesia Coal Basin. The uranium concentration in waters reaches 4,1 μg/dm³ while the activity ratios ranges from 0,4 to 6,5. In all waters radioactive disequilibrium of uranium isotopes - ²³⁸U and ²³⁴U has been found. Within the Southern Upper Silesian Coal Basin two regions are observed which differ in uranium concentration. The central region characterizes low uranium concentration in waters from carboniferous formations (uranium concentration in waters <0,2 μg/dm³). In the East-West region the uranium concentration in waters is high (to 4,1 μg/dm³). 11 refs., 1 fig., 1 tab. (author)

[en] The results of the analysis of microelements may be used to discriminate the coal mine waters of different origin. The microelement ion ratios have been used in the investigations of the possible assessments water hazard and the pollution of the environment. The value of the ratio NH₄⁺/Cl^- up 0.001 indicates the water hazard of the water of the Debowiec Formation in southern part of the Upper Silesian Coal Basin. (author)

[en] The theoretical bases of the determination of ²³⁸U, ²³⁴U, ²²⁶Ra, ²²⁸Ra and ²²⁴Ra in underground waters are presented. The extraction of uranium and radium from waters is described. The application of the method in coal mines in Poland is mentioned. 7 refs., 1 fig. (A.S.)

[en] Natural waters with a high radium content occuring in underground workings of coal mines in Upper Silesia are described. Above 1500 water samples from carbonifereous aquifers were taken and the concentration of ²²⁶Ra was measured. In about 100 samples also uranium was determined. The ²²⁶Ra concentration varied in a wide range from 0.01 kBq/m³ to 270 kBq/m³, while the uranium content was usually much lower than one could expect from the equilibrium between radium and uranium. It was observed that the ²²⁶Ra concentration increases with mineralization of water, however the correlation was rather poor. Two types of radium-bearing waters were distinguished. Waters type A - containing Ba²⁺ ions and waters type B - containing SO₄^2- ions. Waters type A are always reach in radium and usually have higher concentration of ²²⁶Ra than waters type B. The described waters have one of the highest radium concentration which have been found so far in the natural environment. (author)

[en] Studies of the natural radioactivity of the waters of the Upper Silesia Coal Basin have supplied numerous data on the contents of ²²⁶Ra isotope in the waters of the Carboniferous strata. Variation in the ²²⁶Ra concentrations in the waters of the Carboniferous formations has been observed, depending on the tertiary Mezozoic or quaternary overlay. Also found have been variations in the ²²⁶Ra isotope concentrations in the waters outflowing from the particular litostratigraphic strata of the Upper Carboniferous. Very high ²²⁶Ra concentrations have been found in the waters outflowing from the tectonically dislocated zones. 3 refs., 2 tabs. (author)

[en] Upper Silesian coal mines feature high-concentration of radium waters what is an interesting natural phenomenon. Results are presented of radioactivity measurements of those waters drained as tipping waters from bituminous coal mines. Mean ²²⁶Ra concentrations ranged from 0,7 to 28,2 Bq/l (761 pCi/l). 13 refs., 2 tabs. (author)
