  Background and Objective : Natural radioactivity has been the subject of studies for many years. The mean of radiation doses of human from natural sources is about 2.5 mSv/year, but in some regions in the world this value is many times greater than the world mean. Ramsar, a city in Iran, is one of the most important high natural background areas of the world. According to UNSCEAR 2000 report, maximum and mean of the background radiation in Ramsar are 260 and 10.2 mSv/y, respectively. In this study, the high natural radiation effects on the peripheral blood cells of inhabitants of Ramsar was investigated.

  Materials and Methods: In this cross- sectional study 60 healthy residents of HBRA (High Background Radiation Area) and OBRA (Ordinary Background Radiation Area) were randomly selected. Then, a questionnaire designated to gather confounding factors such as age, sex, pregnancy, medications, operations history, cancer and immune related diseases, was filled by interview. Radiation dose rates of their homes were measured by calibrated dosimeter. Two cc fresh peripheral blood of the participants was taken in sterile conditions and the cell count was performed by automatic hematology analyzer (sysmex kx-21, Japan).

  Results: Although the radiation doses received by HBRA inhabitants especially Tulesh Ramsar were significantly higher than OBRA inhabitants, blood cells count between the two groups were not significantly different. 

  Conclusion: Despit the high background doses of the people of the region it is concluded that maybe the blood cell proliferation has been adapted by the living situation.
