Opis:: The artificially produced isotopes of polonium are valuable tracers for radiochemical procedures for the determination of natural 210Po. In this work, the isotopes of polonium (206Po to 208Po) were produced by activation of metallic bismuth targets with 40 MeV protons. The thick target yield of 206Po was 16 MBq/ěAh. Polonium was separated from bismuth by a thermochromatographic method under reduced pressure in static conditions. The bismuth target can be considered as the multiple-use material.

Opis:: In this work empirical functions which relate the full-energy peak efficiency with sample height, energy, matrix composition and bulk density for voluminal samples in a cylindrical counting geometry were found. Accurate determination of the radioactivity of gamma-emitting radionuclides in environmental samples requires taking into account self-absorption. For the obtained self-absorption correction factor, a direct transmission method was chosen. Finally, this paper proposes a simple correlation between the self-absorption correction factor and the bulk density and height of the measured sample for a given energy.

Opis:: The paper presents the results of radioactivity determination of artificial 137Cs and natural 40K in soil samples taken from the Tatra Mountains in Poland (Tatra National Park – TPN). Soil samples were collected as the cores of 10 cm in diameter and 10 cm in depth. These cores were divided into 3 slices. It has been found that the content of 137Cs was the highest at the sites of the altitude over 1300 m a.s.l. The values of 137Cs concentration in the soils examined varied – from 55.8 Bqźkg–1 (dry mass) (417.8 Bqźm–2) for the Tomanowa Pass (1685 m a.s.l.) to 5111 Bqźkg–1 (dry mass) (8400 Bqźm–2) for the Krzyzne Pass (2112 m a.s.l.). In most cases, the values were lower than the average radiocaesium concentration established for Poland.

Opis:: Oil and natural gas exploration is performed using geophysical methods and drilling works. In areas initially identified as prospective for the occurrence of accumulation oil or natural gas based on the analysis of geological data carried out geophysical surveys. The aim of this works is to identify geological structures that could constitute hydrocarbons traps. In the case of finding the appropriate structures, the next stage of exploration work is drilling well for further recognition of the structure. These works allow to explore not only the geological profile but also the physico-chemical properties of drilled rocks and reservoir fluids. Geophysical (mainly seismic) surveys and drilling works can affect the individual elements of the environment: the atmosphere, underground and surface water, ground surface and land and rock environment in different degrees. In order to estimate the risks, threats to all elements of the environment related to the prospection of hydrocarbon deposits have been analyzed (seismic and drilling works). Environmental risk is estimated based on a modified methodology contained in the norm PN 18002. For risks associated with the exploration referred to the consequences of adverse events in relation to the individual elements of the environment and the frequency thereof (by determining the probability of their occurrence). The risk was estimated by multiplying the weight of the likelihood of adverse events weights and consequences. Risk evaluation, indicating danger tolerated, acceptable and unacceptable was also evaluated

Opis:: It has been increasingly realised that geological storage of CO2 is a prospective option for reduction of CO2 emissions. The CO2 geological storage potential of sedimentary basins with the territory of Slovakia, the Czech Republic, Poland, and the Baltic States is here assessed, and different storage options have been considered. The most prospective technology is hydrodynamic trapping in the deep saline aquifers. The utilisation of hydrocarbon (HC) fields is considered as a mature technology; however storage capacities are limited in the region and are mainly related to enhanced oil (gas) recovery. Prospective reservoirs and traps have been identified in the Danube, Vienna and East Slovakian Neogene basins, the Neogene Carpathian Foredeep, the Bohemian and Fore-Sudetic Upper Paleozoic basins, the Mesozoic Mid-Polish Basin and the pericratonic Paleozoic Baltic Basin. The total storage capacity of the sedimentary basins is estimated to be as much as 10170 Mt of CO2 in deep saline aquifer structures, and 938 Mt CO2 in the depleted HC fields. The utilisation of coal seams for CO2 storage is related to the Upper Silesian Basin where CO2 storage could be combined with enhanced recovery of coal-bed methane.
