View Original AbstractThis study found no brain damage from cell phone-like radiation in rats, but examined only short-term exposure using limited detection methods.
Plain English Summary
Japanese researchers exposed rats to 1439 MHz radiofrequency radiation (similar to cell phone signals) for one hour daily over 2-4 weeks to test whether it damaged the blood-brain barrier or caused brain tissue changes. They found no effects on blood-brain barrier permeability, no structural damage to brain cells, and no changes in body weight at exposure levels up to 2 W/kg in the brain. This suggests that short-term exposure to cell phone-type radiation at these levels may not cause detectable brain damage in rats.
Study Details
We investigated the effects of exposure to a 1439 MHz TDMA (Time Division Multiple Access) field, as used in cellular phones, on the permeability of the blood-brain barrier (BBB), on the morphological changes of the brain, and on body-mass fluctuations.
Male Sprague-Dawley (SD) rats were divided into three groups of eight rats each. The rats in the EM(...
HF-EMWs had no effect on the permeability of BBB. The morphological changes in the cerebellum were i...
In conclusion, a 1439 MHz TDMA field did not induce observable changes in the permeability of the BBB, morphological changes in the cerebellums, or body mass changes in rats, as evaluated by the conventional methods.
