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.
Highlights
Numerous sorts of tobacco are grown for a variety of uses
Soil contains radioactive elements that could be due to phosphate ore which is used as a fertilizer in tobacco fields and 210Pb. [2]. the current work is concerned with the determination of the 222Rn concentrations (CRn) and the radon surface exhalation rates in some cigarettes tobacco samples accessible in the local Iraqi markets
Pieces of (1cm2) CR-39 track detector were fixed in the top cover of the plastic cylinder
Summary
Numerous sorts of tobacco are grown for a variety of uses. The sorts of tobacco vary according to tobacco classes according to plant density, manipulation of nitrogen fertilization, height, time of topping, harvesting and curing which is normally and favorably influence the usability of the cured leaves for the specific products [1]. قياس ت اركيز غاز ال اردون ومعدل ال اردون المنبعث من بعض نماذج تبغ الدكائر بغجاد الع ارق، الجامعة المدتنررية، كمية التربية،قدم الفيزياء1 الع ارق، جامعة كربلاء، كمية التربية، قدم الفيزياء2
