This study should investigate in rats whether 1.) radiofrequency electromagnetic fields could induce chromosomal damage in erythocytes of rat offspring whose mothers were exposed during pregnancy and 2.) imbalances in free radical metabolism of rat offspring liver and blood occurs.
The exposure group consisted of six adult pregnant rats (90-110 days old, 200-250 grams) and the control group of four animals.
|ばく露時間||repeated daily exposure, 8.5 h/day, throughout pregnancy|
|Additional information||vertical polarisation|
|Distance between exposed object and exposure source||29.5 cm|
|チャンバの詳細||Faraday cage (101.5 x 64 x 38 cm) made of 0.5-cm mesh|
|ばく露装置の詳細||The rats were housed in individual Plexiglas cages (40.5 x 33.5 x 17.5 cm) that were placed for exposure 29.5 cm away from the mobile phone antenna in its maximum radiation direction.|
|Sham exposure||A sham exposure was conducted.|
|Additional information||The Faraday cage containing the control animal was kept 40.5 cm away from the cage containing the exposure source. Both cages were placed in a wooden rack, and their places were switched every other day.|
A statistically significant increase in micronuclei occurrence was observed in the irradiated group.
No significant differences were found in any oxidative parameter of offspring plasma and liver. Additionally, the average number of pups in each litter has not been significantly altered.
These data suggest that radiofrequency electromagnetic field is able to induce a genotoxic response in hematopoietic tissue during the embryogenesis. An imbalance in free radicals does not seem to play an important role in its genesis.
