Determining the Relation of Electromagnetic Radiation with the Level of Cortisol Hormone of Serum (Blood) of the Male Employees of Golestan Province’s 230kV Substations

Abstract

Introduction: Today the rate of human beings exposed to electromagnetic fields is increasing deliriously and human beings are being more drowned in the ocean of electromagnetic fields each day. It has been a long time that the effects of electromagnetic fields on organisms has been studied by researchers and due to the long-term researches and the slow impact of fields on life-cycle processes, in a lot of cases a final opinion is impossible. Considering the detrimental effects of being exposed to electromagnetic radiations, this study aimed to determine the relation between electromagnetic radiations and the level of Melatonin and Cortisol hormones of serum (blood) of the male employees of the 230kV substations in Golestan Province.
 
 Materials and Methods: this study has been accomplished with the cross sectional method (descriptive-analytic) on male employees of the 230 kilo-Volt substations in Golestan Province(1396). The results achieved from the serum sample of the case and control groups have been compared, and the measurements and the relation between them has been analyzed, using Spss22 software.
 
 Results: 100 % of the measured electric field intensity and magnetic flux density of the 230kV substations in Golestan Province is less than Iran’s occupational limits. There was no significant difference between the average of the level of Cortisol hormone in the case and control groups. The average of the level of Cortisol in the substation job group was not significantly different. There is no significant difference in the average of Cortisol level and age category and work place
 Conclusion: Electromagnetic radiations do not affect the level of Cortisol hormones of the male employees of the 230 kV substations in Golestan province and the electric and magnetic fields intensity of substations is in the occupational limits of Iran.
