Po and Pb radioactivity levels in local and imported tobacco used in Palestine and Jordan.

This study aimed to assess the concentrations of Po and Pb in various tobacco samples from Palestine and Jordan. Cigarette smoking is recognized as a significant contributor to the radiation dose received by individuals, primarily due to the elevated levels of Pb and Po found in tobacco. The analysis revealed that the average concentrations of Po in locally sourced tobacco and cigarette samples in Palestine are 16.
