Purpose: As no mathematically - based study was conducted so far, we decided to conduct this study to mathematically compare the absorbed doses of radiation.
Methods and Material: Seven radiology centers were selected in Gonbad, Golestan to include 140 patients (with confidence level of 95%) for 11 techniques of x-ray such as skull, shoulder, lang, upper and lower digestive tract, hand feet, back and neck. Required data were gathered by a questionnaire focusing on mAs, Kvp, FSD and other items.
Results: Findings of the study revealed a decrease in the absorbed dose of the body surface with various techniques without distortion of the film. ANOVA revealed no significant difference between the means.
Conclusion: these findings are not adequate thus requiring a consideration of all factors involved in reduction of the absorbed dose if a mathematical model is to be suggested.
