Conclusion (acc. to author)
24 out of 60 participants were exposed to a power density of < 60 µW/m², 20 participants to 60 - 100 µW/m², and 16 participants to more than 100 µW/m² .
The values of the stress hormones adrenaline and noradrenaline grew significantly during the first 6 months after starting the GSM base station; the values of the precursor substance dopamine substantially decreased in this time period. The initial condition was not restored even after 1.5 years. Due to the not regulable chronic difficulties of the stress balance, the phenylethylamine levels dropped until the end of the investigation period. The effects show a dose-effect relationship and are situated far under the valid limit values.
