This creates about thirty radioisotopes of more than twenty elements. For organisms, the four of them are most important: 鲁H, 鈦稡e, 虏虏Na, 鹿鈦碈. The natural radionuclides, which are present in Earth crust, also settle on dust and particles of water vapor. By this means, the derivatives of uranium and thorium, and long-life 40K get into the air. 鹿鲁鈦稢s is the most widespread isotope, that is implemented by humans into the environment. To determine the concentration of radionuclides in the atmosphere, high volume air samplers were used, where the aerosol collection took place on a special filter fabric (Petrianov filter tissue FPP-15-1.5). In 2002 the high volume air sampler AZA-1000 was installed at the Polish Polar Observatory of the Polish Academy of Science in Hornsund, Spitsbergen (77掳00鈥橬, 15掳33鈥橢), designed to operate in all weather conditions of the cold polar region. Since 1991 (with short breaks) the ASS-500 air sampler has been working, which is located in Swider at the Kalinowski Geophysical Observatory of Geophysics Institute of the Polish Academy of Science (52掳07鈥橬, 21掳15鈥橢). The following results of radionuclides concentrations were obtained from both stations using gamma spectroscopy analysis: 鈦稡e, 鹿鲁鈦稢s, 鹿鲁鈦碈s, 虏鹿鈦癙b, 鈦粹伆K. For gamma spectroscopy analysis HPGe (High Purity Germanium) detector were used. These data were compared with each other. The preliminary results gave evidence that radioactivity measured in aerosols is not proportional to the amount of dust for both studied regions. Furthermore, the results indicate annual variability (seasonal fluctuations) as well as a decrease in the average activity of 鈦稡e with increasing latitude. The content of 鈦稡e in surface air also indicates the relationship with solar activity cycles. <p class="card-text"><strong>Keywords:</strong> <a
