Opis:
The history of modern geological mapping in Poland began with the Carta Geologica totius Poloniae, Moldaviae, Transylvaniae, Hungariae et Valachiae by S. Staszic, often called the “father of Polish geology”. Before Staszic, a general map of Poland had been published by J.-E. Guettard (1764a); ones of the Sudety Mts. by J. Jirasek (1791), L. von Buch (1797), and Raumer (1813); and that of the Tatra Mts. by Hacquet (1796). In times of the partition of Poland (1772 to 1918), areas annexed by Prussia were covered by systematic geological surveys. These cartographic projects resulted in the compilation of two geological atlases comprising maps of the standard sheet type, in the period from 1826 to 1836. These atlases were compiled by teams of outstanding geologists, under the leadership of L. von Buch and F. Hoffmann. Another outstanding contribution to the geology of Poland was made by G.G. Pusch, the author of the excellent Geognostische Beschreibung von Polen (1833–1836), subsequently supplemented by Geognostyscher Atlas von Polen. One of the greatest achievements of L. Zejszner was the geological map of the Tatra Mts., Carte de la chaine du Tatra, published anonymously in Berlin in 1844, and a series of geological maps prepared as drafts of Geognostic maps of the Eastern District of the Polish Kingdom. Special attention should be also paid to two extensive studies which covered areas of Upper and Lower Silesia. The first of these, Geognostische Karte von Oberschlesien und den Angrenzenden Gebieten, was completed by a team led by F. Roemer, and published in 1870. The second, Geologische Karte von dem Niederschlesischen Gebirge und den angrezenden gegenden, was compiled by a team led by R. von Carnall, and published in the same year. Out of all the studies carried out by Austrian geologists, it is necessary to mention those of E. Tietze, as they produced excellent geological maps of the Carpathians and vicinities of Kraków and Lviv. It is also worth mentioning the contributions made by the Physiographic Commission, active from 1866 until the beginning of the First World War. Its members decided to prepare the Geological Atlas of Galicia. The final product of works of this commission was a set of 25 booklets, with over a hundred geological maps at a scale 1:75000, issued in the years 1885–1912. From 1881, the commission was also publishing its famous Physiographic Diaries, which include papers on the geology of areas annexed by Russia, written by famous Polish geologists such as J. Siemiradzki, A. Michalski, and E. Habdank-Dunikowski, illustrated with relevant geological maps prepared by them.

Opis:
In a region of two lithologic units: the Augustów Plane sandr and the Suwałki sands and fluvioglacial gravels, 134 measurements of radon concentrations in dwelling houses were performed. An integral method of solid state nuclear trace detectors (SSNTD) was used in the studies. Statistically significant differences in the radon concentrations in both geological units were obtained. The radon concentration arithmetic mean was 197 Bq m-3, geometric mean - 119 Bq m-3, median - 111 Bq m-3, the maximal value being 1225 Bq m-3 in the region of the Suwałki fluvioglacial sands and gravels. The Augustów Plane sandr revealed arithmetic mean of radon concentration equal to 123 Bq m-3, geometric mean – 80 Bq m-3, and median equal to 67 Bq m-3, maximal value 695 Bq m-3. The annual effective dose of the radon obtained by inhabitants of the Augustów Plane sandr is 1.7 mSv and for inhabitants of the Suwałki fluvioglacial sands and gravels it is 2.5 mSv.

Opis:
Leaching studies were performed to develop a suitable method for extraction of uranium from domestic uranium ores: dictyonemic shales and sandstones. The extracting procedure was composed of successive separation steps: crushing and grinding, acid or alkaline leaching, solid-liquid separation, and inductively coupled plasma mass spectrometry (ICP-MS) analyses of post-leaching solutions. The influence of such process parameters as temperature, pressure, particle size of solid material, kind of leaching solution and its concentration, on the recovery efficiency of uranium and accompanying metals were tested. The efficiency of uranium leaching with sulphuric acid solution achieved 81%. Satisfactory results were obtained for the alkaline leaching process. It was found that uranium can be selectively extracted by the alkaline leaching solution. Almost complete extraction of uranium from sandstones was achieved when a mixture of sodium carbonate and sodium hydroxide, with hydrogen peroxide as a leaching solution was used.

Opis:
The main objective of the present study was an assessment of the possibility of uranium recovery from domestic resources in Poland. In the fi rst stage uranium was leached from the ground uranium ore by using acidic (sulfuric acid or hydrochloric acid) or alkaline (carbonate) solutions. The leaching efficiencies of uranium were dependent on the type of ore and it reached 81% for Dictyonemic shales and almost 100% for sandstones. The novel leaching routes, with the application of the helical membrane contactor equipped with rotating part were tested. The obtained postleaching solutions were concentrated and purifi ed using solvent extraction or ion exchange chromatography. New methods of solvent extraction, as well as hybrid processes for separation and purifi cation of the product, were studied. Extraction with the use of membrane capillary contactors that has many advantages above conventional methods was also proposed as an alternative purification method. The fi nal product U3O8 could be obtained by the precipitation of ‘yellow cake’, followed by calcination step. The results of precipitation of ammonium diuranate and uranium peroxide from diluted uranium solution were presented.
