No effects of pulsed radio frequency electromagnetic fields on melatonin, cortisol, and selected markers of the immune system in man.
Published in: Bioelectromagnetics 2001; 22 (4): 280-287
Aim of study (acc. to author)
continuous for 4 h
Distance between exposed object and exposure source
The main room of the air
conditioned exposure chamber was subdivided into four compartments open at one side. The inside of the exposure chamber and the compartments were shielded against RF EMF.
Each compartment was equipped with a wooden reclining seat and a circularly
polarised antenna, individually positioned 10 cm behind the head of the upright sitting test person.
In double blind trials, each
test person attended a total of 20 randomised 4-hour sessions of exposure and sham exposure, equally distributed at day and night, being at least 2 days apart after a day session and at least 3 days apart after a night session.
