Measurement of 222Rn gas Concentrations and Radon Exhalation Rates in Some Cigarettes Tobacco Samples
Abstract
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 than other studied samples, however, it is still less than some other average values given in the literatures.Keywords: 222Rn, cigarette samples, (CR-39) detector, tobacco.
