Abstract: The fight to limit smoking and the harmful health and social consequences are led by the 60s of last century. Currently there are several regulations introducing restrictions to curb smoking and improve public health. According to a new theory cause, increased morbidity among smokers receive additional radiation dose consumption of tobacco products. Gross β-activity indicator enables to generally assess the specific activity of all β-active radioisotopes contained in the tobacco as the basis for assessing their passage from the tobacco product to the consumer. The purpose of this study on Burley tobacco is to determine the gross β-activity on harvesting belts and parts of the tobacco leaf. The results show that the leaves of the middle belt, of which the I class is mainly formed, have the highest activity and those of the lower belt with the lowest. In the parts of the tobacco leaf, it was found that the specific activity of the veins exceeded that of the whole leaf of 0.5-2.4 times and that of the lamina by 2.5-4 times.
