Thirty-one samples of cigarettes have been collected from local markets of different types of origins. The samples were selected according to a survey distributed to smokers by paper and digital survey to see the most heavily traded among smokers and in addition to a number of questions to see how the awareness and the culture of smokers in diseases caused by smoking and considered this study the first survey in Iraq. The aim of this research is to assess the number of cancer cases due to cigarette smoking. Through the use of High-Purity Germanium system (HPGe) (efficiency 40%) we determinated the radionuclides in cigarette tobacco. The average values were (14.86 ± 3.76, 10.84 ± 3.13, 1050.64 ± 47.57) Bq/kg for Ra-226, Th-232 and K-40, respectively, and the excess lifetime of cancer risk values ranged from 0.54 to 130 at average of 76 per million person per year. Raeq values varied from 18.50 to 87.21.4 Bq/kg with an average value of 39.51 Bq/kg for tobacco samples. The annual effective dose (HE) varies from 16.38 μSv/y to 44.69 μSv/y with an average value of 24.97 μsv/y. The Annual Gonadal Dose Equivalent (AGDE) varies from 0.3 to 0.64 (mSv/y) with an average value of 0.42 for all tobacco samples under investigation.

Nowadays, using the Internet, for academic and non-academic activities, is an integral part of students’ daily life. Studies showed that excessive use of the Internet has negative effects on physical and mental health. The present research was conducted in order to compare the psychological disorders of Internet addicted students and ordinary Internet users in Zabol University of medical sciences. It applied a causal-comparative method. Through applying purposive sampling method, 252 undergraduate and postgraduate students of Zabol University of Medical Sciences were selected in May 2015. Data collection was performed using standard questionnaires of Young’s Internet Addiction Test and the Symptom Check List 90-Revised (SCL-90-R). Data analysis was carried out using independent t-test with SPSS21. Results indicated that the Internet addicted students, compared with ordinary Internet users had more psychological disorders. Considering the high prevalence of psychological disorders in the Internet addicted students, teaching appropriate use of the Internet to students is an important factor in controlling the Internet addiction.
