Incidence of sister chromatid exchange in bone marrow cells of the mouse following microwave exposure. med./bio.

Published in: Radiat Res 1981; 85 (2): 340-348

Aim of study (acc. to author)

A sister chromatid exchange assay was utilized to investigate potential mutagenic bioeffects of microwave (2450 MHz) radiation on mouse bone marrow cells.



Exposure Parameters
Exposure 1: 2.45 GHz

Exposure duration: 8 h/day for 28days

Exposure 1

Main characteristics
Frequency 2.45 GHz
Exposure duration 8 h/day for 28days
Modulation type CW
Exposure setup
Exposure source
Chamber Environmental chamber lined with microwave absorber maintained at 22°C and 55 % humidity.
Setup Animals kept in 2.54 cm thick Styrofoam cages / 5 cm x 8 cm x 10 cm with the long axis of the cage and the animal parallel to electric field.
Additional info The cages were mounted in slots cut in a large Styrofoam sheet. The cages were located in a circular pattern and the animals were rotated around the circle of cages every 4 h. Control animals was kept in another enviromental chamber identical to the exposure chamber but the animals were not handled and remained in their home cages during the whole exposure period.
Measurand Value Type Method Mass Remarks
SAR 15.6 mW/g minimum calculated whole body 26.80 W/kg maximum value.
