Cell physiological effects of radiofrequency electromagnetic fields.

掲載誌: Physiol Chem Phys 1982; 14 (1): 31-39

この研究は、ヨーロッパアカガエル(R. temporaria)の卵巣内および体腔に存在する卵に、周波数範囲10-27 MHzの無線周波RF電磁界を、最大SAR値800 W / kgまでで与え、卵細胞の膜における等張性および浸透性の水透過性および密度への影響を調べた。その結果、卵巣内の卵の浸透性の水透過性のみが有意に変化し、50 W / kgのSARおよび最大2時間のばく露時間で、約30 %の減少が見られた、と報告している。

研究の主なアウトカム(著者による)

The observed difference in cell density measured before and after exposure was not statistically significant. The isotopic water permeability of matured eggs was not statistically significant altered. The osmotic water permeability of oocytes was significantly decreased after exposure with SAR values of about 50 W/kg.
