To study the behavioral effects of chronic exposure to 0.5 mW/cm² of 2450 MHz microwaves. The study reported here was conducted to replicate the microwave effects described in a previous study (publication 2506).
| Exposure | Parameters |
|---|---|

Exposure 1:
2.45 GHz
Modulation type:
CW
Exposure duration:
repeated daily exposure; 7 h/day for 90 days

rats were assigned randomly into 3 groups: MW exposure group, Sham exposure group and cage-control group.
| Modulation type | CW |

| Exposure source |

|---|---|
| Distance between exposed object and exposure source | 1.05 m |
| Chamber | outside chamber dimensions 3.5 x 3.5 x 2.75 m, covered with absorbers |
| Setup | 14 plexiglas cages (20 x 10 x 9.5 cm) were mounted in a circular array 105 cm from the monopole antenna. |

All groups had similar food intakes and similar body mass. In contrast to the earlier studies (see below) the present experiment provides no indication that microwave irradiated animals were different from sham-exposed controls. Performance of sham- and microwave-exposed animals was reliably different on only one measure, the lever-pressing task. The general conclusion reached was that exposure to CW 2450 MHz microwaves at 0.5 mW/cm² was below the threshold for behavioral effects over a wide range of variables, but it did have an effect on a time-related operant task, although the direction of the effect was unpredictable.
