To investigate the effect of microwave exposure (2.45 and 16.5 GHz) on developing rat brain (35 days old).
Six rats per exposure and sham exposure condition were used (n=24).

Exposure 2:
16.5 GHz
Exposure duration:
continuous for 2 hr/day on 35 days

Chamber | wooden anechoic chamber lined on the inside with pyramidal shaped RF absorbing material |
Setup | 13 cm x 9.8 cm pyramidal horn antenna with the aperture in a distance of 2 d²/λ from the cages; six animal cages made of plexi glass placed inside the chamber in two piles so that 3 cages were put one above the other; six rats were exposed simultaneously |
Sham exposure | A sham exposure was conducted. |

The data showed that the chronic exposure to 2.45 and 16.5 GHz under these experimental conditions caused a statistically significant increase in DNA single-strand breaks (increase in the length of DNA migration) in brain cells of rats.
