Poles are the leaders in Europe in terms of the amount of salt consumed per day. Table salt is the most frequently used spice and is essential for the proper functioning of the body. However, its excessive consumption may have adverse effects on human health. The Word Health Organization (WHO) informs that the leading cause of premature deaths in the European region of WHO is the cardiovascular disease. This is why medicine is increasingly recommending the use of low-sodium salt, which contains a reduced content of sodium and an increased content of potassium because it is essential for the proper functioning of the brain, cells and for proper work of muscles. There is no information in the literature on the concentration of natural radioactive isotopes present in sodium-reduced salts used as a substitute for table salt. Therefore the aim of this study was establishing the concentration of natural radioactive isotopes in salt samples with low sodium content available in retail sale on the Polish market and widely used in Polish households. In these salt samples analysed was the concentration of natural radioactive isotopes like radium, thorium and potassium with use of Mazar type gamma radiation spectrometer connected with a scintillation probe NaI (Tl). Concentration of 226Ra and 232Th isotopes in the tested salt samples with reduced sodium content amounted to below the background level of determination, and the 40K content was within the limits 3386–5794 Bq∙kg-1. Additionally on the basis of the established concentration of natural radioactive isotopes, the annual loading effective dose was calculated for women and men classified to the group of adults from the point of view radiological protection. The effective dose limit of 1 mSv∙y-1 was not exceeded for any test subject consuming reduced sodium salts.. The obtained results were compared with reported data from other countries available in the literature.
