Smokers and non-smokers are at risk of developing lung cancer when exposed to alpha rays in influence of the relatively low levels of radium and radon that may be present in different tobacco species. There is great interest in studies and research on the radionuclides emitting alpha particles in narghile tobacco to know the relationship of smoking narghile us to cancer, especially lung cancer.
Material and Methods
In this work, alpha radiographic measurements were carried out in 30 different narghile samples in Iraqi markets. Radon concentrations were determined using time-tested passive radio doses containing CR-39 solid state pathway detectors.
The radon concentrations in samples varied from (and27.44±4.4 Bq/m3) to (214.61±18.1 Bq/m3) with an average value (65.60±41.04 Bq/m3). The annual effective dose vary from (0.69±0.09 mSv/y) to (5.41±2.20 mSv/y) with an average value (1.64±1.03 mSv/y) . The lung cancer risk cases per year per million person vary from (12.46±2.11) to (97.45±7.34) with an average value (29.77±18.63) per million person. The effective radium content ranged between 0.054Bq/kg and 0.425Ba/kg with an average value 0.131 bq/kg, while the radon emission values for the mass and surface units ranged from 0.410 to 3.212 with an average 0.996mBq/kg.h and 9.040 to 70.703 with an average 21.943mBq/m2.h, respectively.
The results of the study showed that they are within the internationally accepted limits and presently do not pose a threat to human health and life in terms of the radiation activity of the studied narghile tobacco species selected in this study.
