Aim of study (acc. to author)

To investigate whether electromagnetic radiation (EMR) from a cellular telephone (900 MHz) induces histological changes in rat Merkel cells.

Background/further details

Merkel cells are a special kind of sensory cells which could be found in the epidermis.

Exposure 1

Main characteristics
Frequency 900 MHz
Type
Exposure duration continuous for 30 min
Modulation
Modulation type pulsed
Exposure setup
Exposure source
Setup The mobile phones were positioned in close contact with the rats at a distance preventing mechanical stimulation of the snouts.
Additional info The phones were either turned to the speech position (established contact) or to the standby position. The latter seems to be considered by the authors as sham exposure.
