Do cellular phones alter blood parameters and birth weight of rats?

掲載誌: Electro Magnetobiol 2000; 19 (1): 107-113

この研究は、携帯電話から放射されるマイクロ波MW)が、ラットの末梢血パラメータおよび出生体重に及ぼす影響を調べた。36匹のアルビノラットを4つのグループに分けた。オスの擬似ばく露群(n = 6)、メスの擬似ばく露群(n = 12)、オスのMWばく露群(n = 6)、メスのMWばく露群(n = 12)である。その結果、ばく露後の血液パラメータに差はなかった(p> 0.05);MWばく露群の子孫の出生時体重は、擬似ばく露群よりも有意に低かった(p <0.001);擬似ばく露群とMWばく露群の直腸温度の間に有意差は観察されなかった(p> 0.05); SARは0.155 W / kgであった;調査したすべてのパラメータは、次世代のラットで正常であった(p> 0.05)、と報告している。

ばく露装置
ばく露の発生源/構造
Distance between exposed object and exposure source 0.5 cm
チャンバの詳細 anechoic chamber 70 cm x 47 cm x 47 cm built with styrofoam blocks
ばく露装置の詳細 Rats were individually placed in methacrylate cages of 20 cm x 10.5 cm x 10 cm and oriented parallel to the electric vector but normal to the magnetic and pointing vector of the EMF. The mobile phones were placed 0.5 cm under the cages.
Additional information Females were exposed until they gave birth. Males were exposed for 1 month. When the offspring became sexually adult, the experiment was repeated on them. Animals in the sham groups were treated identically but no EMF was emitted from the mobile phones.

研究の主なアウトカム(著者による)

Exposure of normal and pregnant rats to low-level 915-MHz radiofrequency radiation (RFR) did not cause detectable shifts of erythrocyte or leukocyte numbers in peripheral blood, nor did it influence the course and the outcome of pregnancy. The only consistent finding related to the RFR exposure was lowered birth weigth, which was overcome in postnatal development during a 3-month period.
