In this research we have studied the effects of extremely low frequency magnetic field on the peripheral blood lymphocytes chromosomes of human in vitro and rat in vivo. By this means, we used 60 blood samples of 10 men as well as 40 rats. Of 60 human blood samples ,40 samples (in two group of 20) were selected as test groups and placed into the 2 mT and 35 Hz magnetic field. The blood samples,then, with 20 samples of control groups cultured for chromosomal analysis of lymphocytes cells.Of 40 rats, 30 rats, in two group of 15, were also placed into the same magnetic field, and cultured with 10 control rats for chromosomal analysis of lymphocytes cells.The analysis results of 5373 metaphasic cells from human bloods(3573 test cells and 1800 control cells) showed that there was no significant differences among the percentages of chromosomal aberrations of control(0.16%), 30 and 60 minutes test (0.224%,0.296%) groups respectively (p30´>0.28,p60´>0.15). There was no chromosomal aberrations in 3089 metaphasic lymphocytes of rats (2389 test cells and 700 control cells).
