16 male rats were separated into a control and an experimental group. For the experimental group the phones transmitted speech for 20 minutes per day for one month.
Modulation type: pulsed
Exposure duration: repeated daily exposure, 20 min/day, for 1 month
|Distance between exposed object and exposure source||5 mm|
|Chamber||The rats were confined in Plexiglas cages (20 cm x 10.5 cm x 10 cm) with ventilation holes, and the mobile phones were placed under the cages.|
|Setup||Exposure began when the rats settled down to a prone position and selected a fixed location inside the cage spontaneously.|
|Sham exposure||A sham exposure was conducted.|
|Additional info||The same phones were placed under the control rats but they were turned off.|

The results showed that 20 minutes of the irradiation emitted from 900 MHz cellular phones did not alter anti-apoptotic bcl-2 protein in the brain and testes of rats.
It was concluded that bcl-2 may not be involved in the effects of irradiation on the brain and testes of rats.
