Established a few months after regaining independence in 1918, the Polish Geological Institute was carrying out research aimed at ensuring the supply of necessary mineral raw resources to the domestic industry. The director of the Institute, Prof. J. Morozewicz as well as the state authorities were aware of the fact that for the proper functioning of the Institute suitable headquarter was needed. Therefore, already in the mid-1919, the appropriate area and financial resources were allocated for the construction of large buildings, the designer of which S W0łk0wicZ T M Pervt was Prof. M. Lalewicz. The laboratory pavilion was opened in 1926. The main building, which was put into use in 1936 and rebuilt after the destruction during World War II, has been the pride of the Institute until today. The extension of the state and a wide range of research issues meant that already in 1921, it was necessary to establish the Upper Silesian Station in Dąbrowa Górnicza, whose activity was focused on the coal geology. The Geological Station in Borysław, operating in the structure of the PGI since 1920, was transformed three years later into the Oil and Salt Department of the PGI, which closely co-operated with the Carpathian oil industry. The Holy Cross Mountain research group was located during 1937-1955 in the family home of Jan Czarnocki. After World War II, due to the significant intensification of geological research and exploration in Poland, new regional divisions of the Institute were established that currently have their headquarters in Kraków, Sosnowiec, Wrocław, Kielce, Gdańsk and Szczecin; all have the rank of branches. The organizational structure of the PGI is of an extremely regional nature, and the research issues of individual branches are mostly related to the recognition of the geological structure and mineral resources occurring in a given region. In addition, the Polish Geological Institute possesses 8 core repositories.

The search for uranium in Poland began after the World War II and was initially conducted by Russians who in the mid-1950s were replaced by the Polish specialists. The Polish Geological Institute also took part in this research in 1956. In the initial phase of the search, the study was focused on the area of the Sudetes. Later, the research covered the entire territory of Poland using the so-called "parallel research”, which consisted mainly in the analysis of geophysical measurements from all the boreholes performed in Poland, and then the collection of samples from the zones with anomalous radioactivity. In this way, concentrations of uranium were found in the Lower Ordovician Dictyonema Shale of the Podlasie Depression and in the Lower Triassic of the Peribaltic Syneclise. Uranium was also searched in the area of the Carpathians, the Holy Cross Mountains, hard coal deposits of the Upper Silesian Coal Basin and in brown coals and phosphates. Uranium deposits in Poland have not been found and the current concentrations are not of economic value. Research methodology, which was used for uranium prospection in the 1990s, was successfully applied in geoenvironmental study, first of all for establishing post-Chernobyl cesium contamination and for preparing a map of the radon potential of the Sudetes.
