[en] In this article the method of the measurement of the terrestrial radioactivity by the transferable gamma-spectrometers with Na(TI) 76 x 76 mm with the scintillation detectors and the air gamma-spectrometry on the area of the Czech Republic is described. The radiometric map of the Czech Republic 1:50000, brought out in 1995, expressed in dose rate input of gamma-radiation, is based on regional (1957-1959) and detail (1960-1971) air measurement of the summary gamma-activity, of the air gamma-spectrometry (from 1976) and it was amplified with the results of the terrestrial and laboratory radiometric measurements. The method of feed back calibration was realized in 1994 with the means expression of the data in dose rate and equalization of data of the map. The map of the iso-lines with the step 10 nGy.h^-1 was weaved by computer processing with the crining method. The regional terrestrial radiation in the Czech Republic, which is formed igneous, sedimentary and metamorphic minerals is in the range 15-200 (6-245) nGy.h^-1 with the average value (65.6+-19.0) nGy.h^-1. The radiometric map of the Czech Republic 1:500000 was verified in 1995-1996 by comparison with the terrestrial gamma-spectrometric measurement. The middle difference of the comparing sets 2.1 nGy.h^-1 indicate good regional equalization of the data while middle difference +-13.8 nGy.h^-1 illustrate expected difference for the individual locality. The correlation coefficient of data of the comparing sets (N=81) is 0.942. The radiometric maps of the Saxon and of the Czech Republic in the border zone with the length about 250 km were compared. The middle difference (1.3+-13.6) nGy.h^-1 nGy.h^-1 indicate good unity of the data. The radiometric maps of the Poland and of the Czech Republic in the border zone with the length about 300 km were compared in 1977. The middle difference (12.1+-17.9) nGy.h^-1 with higher values in the Czech Republic indicate the disunity of presentation of the radiometric data. The analysis of reasons of difference of the radiometric data are given

[en] The main goal of the joint Slovak-Hungarian monitoring is to mutually record and evaluate the impacts of the water supply by the underwater weir. The evaluation includes the changes in the hydrological regimes of the surface and ground water, the changes in the surface and ground water quality, the changes in soil moisture and changes in forestry and biota. The goal of the mutual data exchange is to provide information on monitoring results characterising the environmental changes on the influenced area of the respective Parties. The basic condition of data exchange is use of equal or compatible methods of measurements and analysis and the application of agreed interpretation methods. The final goal of the Joint Annual Report is to submit the joint evaluation of the monitoring results and the joint recommendations for monitoring improvement and environment protection activities to the respective governments

[en] In 1996 the surface water quality measurements were performed, according to the Agreement, at 8 profiles on the Hungarian territory and at 15 profiles on the Slovak territory. Basic physical and chemical parameters (as water temperature, pH values, conductivity, suspended solids, cations and anions (nitrates, ammonium ion, nitrites, total nitrogen, phosphates, total phosphorus, oxygen and organic carbon regime parameters), metals (iron, manganese and heavy metals), biological and microbiological parameters (coliform bacteria, chlorophyll-a, saprobity index and other biological parameters) and quality of sediment were measured
