この研究は、ラットを用いた実験で、携帯電話に用いられるマイクロ波放射がラットの脳に生じさせる酸化ストレス、認知障害、および炎症の程度を評価した。オスのフィッシャー-344ラットに、900 MHzまたは1800 MHzのマイクロ波放射を30日間（2時間/日）与えた。それぞれのばく露におけるSAR は、5.953×10-4 W / kgおよび 5.835×10-4 W / kgであった。その結果、マイクロ波ばく露群では、擬似ばく露群に比べ、ラットの脳組織における認知機能の有意な障害および酸化ストレスの誘発が観察された；マイクロ波ばく露群では、ばく露後にサイトカイン（IL-6およびTNF-α）のレベルの有意な上昇が観察された、と報告している。

To investigate the effects of an exposure to microwaves on cognitive performance as well as oxidative stress level and cytokine production in rats.
|ばく露時間||2 h/day, 5 days a week for 30 days|
|Distance between exposed object and exposure source||1 m|
|チャンバの詳細||during exposure rats were restrained in a closed box (30 cm x 20 cm x15 cm) divided in 4 compartements with holes of 1 cm for ventilation; 6 rats were placed within the device in two such boxes simultaneously|
|ばく露装置の詳細||GTEM cell was a pyramidal tapered, dual terminated section with outer cell dimension of 220 cm Œ 120 cm Œ 80 cm; microwave chamber was lined with absorbers to minimize reflections|
|Sham exposure||A sham exposure was conducted.|
In the elevated plus maze and the Morris water maze, the spatial memory and learning was significantly decreased in the exposed groups in comparison to the sham exposed group. No significant differences occurred between the exposure groups.
In the exposed group the levels of the lipid oxidation and protein oxidation as well as the levels of interleukin-6 and tumor necrosis factor alpha were significantly increased and the level of reduced glutathione was significantly decreased compared to the sham exposed group.
The authors conclude that exposure to microwaves could lead to cognitive impairments in rats and that these effects could be due to an increased oxidative stress level.
