Effects of the 1900 MHz electromagnetic field emitted from cellular phone on nocturnal melatonin secretion.
Published in: J Physiol Anthropol Appl Human Sci 2003; 22 (1): 61-63
Aim of study (acc. to author)
- mobile communications
Distance between exposed object and exposure source
Subjects stayed in a climatic chamber with the receiver directly attached to the left ear.
On one day the receiver emitted an EMF, while on sham day there was no emission. The subjects did not know the exposure condition.
- isolated bio./chem. substance
Investigated organ system:
Time of investigation:
- during exposure
- after exposure
