[en]Vardar river with its length of 301.6 km and its catchment area of 28,338 km2 covers almost 80% of the territory of the Republic of Macedonia. Various usage of the surface and underground water flows of this hydro system (water supply, irrigation, etc.) to which gravitate cca 2/3 of the population of our Country, are subject of increased interest for their protection. In this sense, radioecological investigations (due to a presence of a local not well prospected uranium deposits and a factor, for phosphate fertilizers) were in progress. The first preliminary results of performed gamma-spectrometric analysis showed that besides many others, the following isotopes: I-131, I-132, Cs-134, Cs-137 and Ru-103, dominated into the investigated water, air and food samples. Different from the concentration of I-131 into the filtered Skopje air which was 12 Bq/m3 on the 5th of May, 1986, the concentration of Cs-137 was up to 15 Bq/m3 in air, 122 Bq/L in local precipitation, up to 800 Bq/kg in sediments and 0.29 Bq/L in the water samples from the Vardar river
