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.
Background/further details:
Animals were divided in two groups consisting of seven rats from a single litter (one group served as control group).

Endpoint

• effects on the neurological system: EEG

Exposure
General category: microwaves, PW (pulsed wave), 2.45 GHz

Field characteristics	Parameters
2.45 GHz pulsed (PW) exposure duration: continuous for two weeks; started on the sixth day after birth	power flux density: 8.26 mW/cm²

Exposed system:
animal (species/strain): rat/Wistar
partial body exposure: head

Methods
Endpoint/Measurement parameters/Methodology

• effects on the neurological system: bioelectrical activity (EEG)
• thermoregulation: body temperature

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.
