Effects of low level microwave radiation on the digestive transit of the rat. med./bio.

Published in: J Microw Power 1979; 14 (3): 287-289

Aim of study (acc. to author)

To investigate possible effects of a low level 2450 MHz microwave exposure on digestive transit of rats and the duration of those effects.

Main outcome of study (acc. to author)

After a 4h exposure no effects were observed. However, after a 8h exposure an acceleration of the digestive transit was found, that hold on for 24h. This acceleration was not any longer observed after 36 and 48h, respectively. Rectal temperature was not altered 60-90 seconds after exposure.
