The aim of this paper is to study the effect of electromagnetic radiation (EMR) on the excretion rates of stress hormones of medical staff in physiotherapy. The excretion rates of stress hormones cortisol, adrenaline and noradrenaline were followed during morning shift in 15 female physiotherapists using RIA kits and a spectrofluorimetric method. The mean number of treatments with EMR emitting devices per month and the emission of each device was assessed. A control group of nurses, matched by age, sex and work task was used. The psychosocial factors were evaluated and no differences between the two groups was found. Calculations of the individual EMR exposure show levels above the ICNIRP guidelines. Significantly higher excretion rates of cortisol, adrenaline and noradrenaline among the studied physiotherapists in comparison with the control group of nurses were found. In conclusion, our data showed that EMR influenced the excretion rates of stress hormones of medical staff in physiotherapy.
