Medical/biological Study (experimental study)
Influence of pulsed wave microwave radiation on the rat EEG during the postnatal period (brief report). med./biol. By: Drecun M, Jamakosmanovic A, Nakas M
Published in: Period Biol 1990; 92 (4): 439 - 440 ( Journal web site )
Aim of study (according to author)
To evaluate possible effects of repetitive low-level pulsed wave microwave radiation on the bioelectrical activity of developing rat brain.
Animals were divided in two groups consisting of seven rats from a single litter (one group served as control group).
- effects on the neurological system: EEG
General category: microwaves, PW (pulsed wave), 2.45 GHz
| 2.45 GHz |
exposure duration: continuous for two weeks; started on the sixth day after birth
|power flux density: 8.26 mW/cm² |
FIELD View further expo parameters
animal (species/strain): rat/Wistar
partial body exposure: head
investigation on living organism
- effects on the neurological system: bioelectrical activity (EEG)
- thermoregulation: body temperature
investigated organ system: brain/CNS
time of investigation: after exposure
Main outcome of study (according to author)
The EEG of exposed rats is characterized with a slight rise in wave amplitude and some slower rhythm. Visual analysis of the EEG shows no conspicuous changes in bioelectrical brain activity between the exposed and control group. Based on the absence of EEG changes the authors suppose that the total absorbed energy of 79.3 J/g of body weight is sufficient only to cause latent alterations in brain function which are not manifested on the baseline EEG.
