Abstract

Background: The concentration of radionuclides in the saliva and blood samples are a good indicator of the human body’s radioactive contamination, the objective of current study was to design across sectional study to assess the alpha particals emitted from the smoker and nonsmoker saliva and blood samples. Materials and Method: The saliva and blood samples were collected from 88 healthy male and famel smoker and non-smoker aged 18- 82 years old. In saliva and blood samples from smokers and nonsmokers, the alpha track density was determined utilizing the efficient fission track analysis approach with CR-39 nuclear track detector. Results: High mean value of alpha track density was significantly seen in smoker saliva and blood samples compared to nonsmoker  samples with percentage difference 23% and 9% respactively. There was a positive correlation between smoker age and the alpha emission rate in blood and saliva samples. Conclusion: The smoker and nonsmoker saliva and blood samples did not have equal distribution of alpha track density. According to their standardized coefficients (ß), in saliva and blood samples, the stronger significant impact of alpha emission rate was seen  at ß = 0.318 with age interval (70-82) in saliva samples Whil the lowest was found at ß = 0.156 with age interval (44-56) in blood sample.
