Study type: Medical/biological study (experimental study)

Microscopic observation of living cells during their exposure to modulated electromagnetic fields. med./bio.

Published in: Bioelectrochemistry 2008; 74 (1): 9-15

Aim of study (acc. to author)

To study mitosis progression and mitosis duration during and after the exposure to the modulated radiofrequency fields.

Background/further details

A TEM cell with holes was developed to allow the cell microscopic visualization during 1 h GSM electromagnetic field exposure of 2.2 W/kg (SAR value), at 30°C, in culture medium.

Main outcome of study (acc. to author)

900 MHz GSM electromagnetic field exposure of 2.2 W/kg SAR value applied for 1 h did not affect either the mitosis progression or the mitosis duration in these experimental conditions. Endocytosis rate was increased (validating the use of the TEM cell).
The authors describe an improved experimental set-up which allows the continuous microscope cell observation during their exposure to GSM electromagnetic fields under well controlled conditions.
