To study the effects of radiofrequency irradiation emitted from cellular phones on 1) trace elements such as manganese, iron, copper, zinc, 2) T1 relaxation times in serum, and 3) rectal temperature of rats.
|Exposure duration||repeated daily exposure, 20 min/day, 7 days a week for 1 month|
|Repetition frequency||217 Hz|
T1 relaxation time and the concentrations of iron and copper in the serum of the exposed group were not changed compared to the control group. However, manganese and zinc values of the exposed animals were significantly different from the control animals. The difference in rectal temperature measured before and after irradiation in the exposed animals was not statistically different from control.
