Influence of electromagnetic fields emitted by GSM-900 cellular telephones on the circadian patterns of gonadal, adrenal and pituitary hormones in men.
Published in: Radiat Res 2008; 169 (3): 337-343
Aim of study (acc. to author)
healthy male volunteers in the age of 20 to 32 years participated in this study. To account physiological circadian alterations in the hormone levels blood samples were collected hourly during the night and every 3 hours during the day. Each individual's hormone concentration before the exposure was used as his control. Endpoint
, 2 h/day, 5 days/week, for 4 weeks
exposure sessions, the attention of the volunteers and a correct normal use position of the mobile phone were maintained by TV projection of movies. The audio signal from the TV set was distributed to four fixed telephones that could be called from the GSM handsets to hear the movie soundtrack.
subject, exposure was on the same side of the head for all sessions.
sham exposure was conducted.
sham exposure was also performed on the days of the first and the last blood drawing sessions by switching the RF output to a 50-Ω dummy load instead of the antenna and presenting the movie sound directly on the TV speakers.
