Measurement of Natural Radioactivity in different cigarettes samples by using (HPGe) detector
Abstract<p>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 U<sup>238</sup> and series Th<sup>232</sup> in addition to K<sup>40</sup> 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 K<sup>40</sup>, series U<sup>238</sup>, series Th<sup>232</sup></p>

Measurement of 222Rn gas Concentrations and Radon Exhalation Rates in Some Cigarettes Tobacco Samples
Twelve cigarette tobacco samples of various brands and origins were gathered from local markets of Iraq. . The CRn was determined utilizing CR-39 track detectors which were exposed to the various brands of cigarettes tobacco for 45 days. The results demonstrated that the highest value of 222Rn concentration was )157 Bq/m3( in Macbeth cigarette sample of Brazilian origin and the lowest value of CRn was (76.3 Bq/m3 (in Sumer cigarette sample of Iraqi origin,with an average value of (106.53±22.3 Bq/m3). The outcomes have demonstrated that cigarettes of a Brazilian origin contain higher CRn tha
