Measurement of Natural Radioactivity in different cigarettes samples by using (HPGe) detector

Abstract

Twelve samples of cigarettes have been collected from local markets of different types and origins by using (HPGe) detector, and measurement of the specific activity for series U238 and series Th232 in addition to K40 in order to estimate the health risk of cigarettes their by smokers, the results shown that highest specific activity value were be (12. 8±6. 3 Bq/kg, 8. 41±5. 8 Bq/kg, 125. 16±58. 3 Bq/kg), respectively, in the sample (MAC) MacBeth type cigarettes in Brazilian origin, this paper reports data such as (specific activity of K40, series U238, series Th232 and some parameters hazard indices) on the radioactivity of tobacco leaves so as to know contaminate those cigarettes in natural radioactivity and Suitability of its use by smokers.

Measurement of 222Rn gas Concentrations and Radon Exhalation Rates in Some Cigarettes Tobacco Samples

“…The radon exhalation rate (RER) was calculated utilizing the relation [5]: C: integrated radon exposure. V: volume of air in the cylinder ,λ: decay constant for 222 Rn ,A : surface area of the sample , T : exposure time .…”
