Study type: Medical/biological study (experimental study)

Chronic exposure of rabbits to 0.5 and 5 mW/cm² 2450-MHz CW microwave radiation. med./bio.

Published in: Bioelectromagnetics 1983; 4 (1): 63-77

Aim of study (acc. to author)

To investigate the effects of 2450 MHz (continuous wave) microwave exposure on rabbits.

Background/further details

Blood samples and eyes were studied followed by pathological examination of inner organs. Furthermore body mass and food consumption were determined.
