Aim of study (acc. to author)

To study whether 2450 MHz microwave radiation (CW) could induce somatic mutations in young embryos of Drosophila melanogaster. A genetic system was used comprising a transposable genetic element in the X-chromosome.

Endpoint

Exposure

Exposure Parameters
Exposure 1: 2.45 GHz
Modulation type: CW
Exposure duration: continuous for 6 h

Exposure 1

Main characteristics
Frequency 2.45 GHz
Exposure duration continuous for 6 h
Modulation
Modulation type CW
Exposure setup
Exposure source
Distance between exposed object and exposure source 0.4 m
Chamber A magnetron was coupled to a waveguide which was terminated with a horn antenna. The wall behind the sample was lined with microwave absorbing material.
Setup Control samples were treated the same way except for the exposure to microwaves.
Parameters
Measurand Value Type Method Mass Remarks
SAR 100 W/kg mean determined by power loss - -
Additional parameter details

The output power was monitored with a power meter connected to the waveguide directional coupler situated between the magnetron and the antenna. The power flux density at the position of the sample was measured with a power density meter.
