Effects of pulsed high-frequency electromagnetic fields on the neuroendocrine system.
Published in: Neuroendocrinology 1998; 67 (2): 139-144
Aim of study (acc. to author)
continuous for 8 h
Distance between exposed object and exposure source
subjects slept in a specially constructed metal-free bed that was enclosed in a metal-free chamber lined with RF-absorbing material.
antenna was positioned beneath the head of the bed at a distance of 40 cm to the vertex of the subject and was operated from the neighbouring room via an extension lead.
sham exposure was conducted.
adaptation night, polysomnographies were performed during two successive nights. The subjects were exposed in one night and sham-exposed in the other night ( randomized and blinded).
