The aim of this study was the determination one of the most radiotoxic elements, 210Po in different parts of tobacco plant from Poland. Investigation revealed that polonium is non-uniformly distributed within tobacco plant. Tobacco leaves constituting about 50% of the wet mass, contain 87.1% of the total burden of 210Po. Among the analyzed leaves about 66% of polonium is located in the oldest, over-ground part. The data obtained here indicate that 210Po is generally taken up by tobacco from the dry or wet deposition of the radioactive fall-out onto the plant. Moreover, 210Po concentration in tobacco leaves from Poland are higher than that in the other countries.
