この実験研究は、10匹のWistarアルビノ種の雄ラットをばく露群と対照群(各5匹)に分け、ばく露群には2.437GHzの標準的Wi-Fiインターネットアクセス装置からの無線周波電磁界を1日24時間、20週間のばく露を与え、ばく露終了後、ラットを屠殺し、心臓内血液の血清8-ハイドロキシ-20-デオキシグアノシン(8-OHDG)レベル測定、精巣の組織学的および免疫組織化学的検査を行った。その結果、ばく露群において、血清8-OHDGレベルおよび精巣組織の8-ハイドロキシグアノシン染色における有意な増加が観察されたことについて、著者はばく露によるDNA損傷を示唆していると報告している。

To investigate the effects of radiofrequency irradiation emitted from WiFi devices on rat testes.
10 rats were divided into an exposure and a control group (each group n=5).
周波数 | 2.437 GHz |
---|---|
タイプ |
|
ばく露時間 | continuous for 24 h/day for 20 weeks |
ばく露の発生源/構造 |

---|---|
チャンバの詳細 | rats were housed in acrylic-glass cages (20 x 30 x 40 cm) |
ばく露装置の詳細 | three cages were placed in a row with 1 - 2 animals each; two commercial ADSL 2 devices + gateways were located at a distance of 25 cm at both longitudinal sides of the middle cage; gateways were wirelessly bridged to each other |
Sham exposure | A sham exposure was conducted. |
Additional information | ADSL 2 contains of hard disk and network storage link; data transmission was performed after each hard disk was assigned as a network drive |
The authors found significant increases of 8-hydroxy-2-deoxyguanosine levels in the serum and testes of the exposed group. Additionally, the enzyme activities of catalase and glutathione peroxidase were decreased in the exposed animals.
The authors conclude, that continuous long-term WiFi exposure oxidatively affects the testes in growing rats.
