Abstract

The effect of chronic exposure on Ramsar HBNRAs inhabitants' health was studied using Cytokinesis Blocked Micronucleus (CBMN) Assay. The results showed a significant difference (P <0.001) in the mean frequency of micronucleus of the study group, or resident in Ramsar HBNRAs, and the control group, which were selected from Tonekabon, a city near Ramsar. Significant differences (P <0.001) were observed between the mean micronucleus frequency after irradiation of blood samples, which means that after irradiation of blood samples, the control group showed a higher increase in micronuclei frequency than the study group that can be as a result of the existence of a radio adaptive response in Ramsar HBNRAs. The correlation was observed between the frequency of micronucleus and age in control groups but was not obtained for the study group.
