The animals were divided into the following four groups (n=20/group): 1) male sham exposure group, 2) male combined radiofrequency exposure group, 3) female sham exposure group, and 4) female combined radiofrequency exposure group.
|Chamber||2295 mm x 2293 mm x 1470 mm reverberation chamber with stainless walls; five cages placed in the exposure chamber; two rats placed in a 420 mm x 260 mm x 160 mm autoclaved polycarbonate cage; cage positions changed daily|
|Sham exposure||A sham exposure was conducted.|
No animal died during the 12-month experimental period. No significant alterations in body and organ weights were observed under the simultaneous combined radiofrequency exposure. The data did not show any significant alterations based on urinalysis, haematology, blood biochemistry, or histopathology in most of the rats. The total tumour incidence was not different between sham exposed and exposed animals.
However, some altered parameters of the blood count and serum chemistry were found in radiofrequency exposed rats: The mean corpuscular haemoglobin in radiofrequency-exposed male rats was significantly increased compared with the sham exposed rats (however, no significant difference was observed in female rats). Additionally, the value of alkaline phosphatase was significantly increased only in radiofrequency exposed male rats and the values of total bilirubin and lactate dehydrogenase were decreased only in radiofrequency exposed female rats with statistical significance.
In conclusion, the data suggest that one-year chronic exposure to CDMA (849 MHz) and WCDMA (1.95 GHz) simultaneously did not increase chronic illness in rats, although there were some altered parameters in the blood count and serum chemistry.
