    Hormone levels of people occupationally exposed to radiofrequencies
    (1999) Dasdag S.; Balci K.; Kaya H.; Celik M.S.
    The present article intended to investigate some hormone levels of technicians in the radio-broadcasting, television (TV) and radio - link stations. The study was carried out on 43 technicians from 20 to 59 years age occupationally exposed to radiofrequency (RF) and microwave (MW) radiation. 20 unexposed and voluntary persons from 20 to 59 years age were accepted as a control group. We determined the levels of some hormones as triiodothyronine (T3), tetraiodothyronine (T4), thyroid stimulant hormone (TSH), free T4, estradiol, dehydroepiondrosterone sulfate (DHEA), testosterone, cortisol and progesterone in the technicians under investigation. The hormone levels of exposure groups were statistically compared with the unexposed control group. T3, T4, estradiol, testosterone and progesterone levels of technicians in the radio-link and TV transmitter stations were found to be significant (p < 0.05, p < 0.001). T3, T4, TSH, estradiol and progesterone levels of technicians in the broadcasting station were also found to be significant (p < 0.001). In conclusion some hormone levels of technicians under investigation were altered by RF/MW.
