Conclusion (acc. to author)

No significant association was observed between the occurrence of non-specific physical symptoms and the actual distance to mobile phone base stations or power lines while sociodemographic and psychological factors have a significant effect on symptom report. Higher self-reported environmental sensitivity, perceived proximity to base stations and power lines, lower perceived control, increased avoidance, living in a rented home, female gender, lower educational level and incapacity for work were significantly associated with increased report of non-specific physical symptoms.
