Electromagnetic waves of 900 MHz in acute pentylenetetrazole model in ontogenesis in mice.

The purpose of this study was to measure the effects of electromagnetic waves (EMW) at 900 MHz. EMW were produced by a signal generator and were administered to mice via an antenna. The frequency of the waves was tested by a spectrum analyser and a frequency-meter. The emitted power was 0.25 mW. A total of 117 mice (59 prepubertal and 58 adult) was used. Mice were exposed to EMW or sham radiation for 2 h and 20 h before an injection of pentylenetetrazole (PTZ). A statistically significant difference was found between the latency measurements within 20 h for prepubertal mice in stages 1 and 2 ( p<0.05). The effects on prepubertal mice of long-term 900 MHz EMW in a PTZ model may be an indication of possible problems in developing brains.
