Abstract
The present study was designed to:
1. Study the hormonal changes in individuals who were exposed to radiation and those changes in hormones may contribute to dysfunction of th hypothalamic pituitary testicular axis.
2. Evaluate the protective efficacy of oral adminstration of vitamins
E and C against radiation hazards.
To achieve this demanded goal, 60 adult male persons were participating throughout this work including 30 subjects were working in the Reactor Department, Nuclear Research Centre in Anshas. They were considered as an exposed group, and were liable to different types of radiation (alpha, beta, gamma and neutrons). Seven persons (23.3%) were working in primary circuit (P.C. and Reactor Hall (R.H), which are the sites with highest exposure. Only three persons were working in the reactor site and they represented 10%. The largest group of exposed persons, 8 persons (26.8%) were working in the Electric Station (E. station). At the workshop (W.) and Secondary Circuit (S.C.) five persons (16.6%) were employed. The last seven Coworkers (23.3%) are distant from the reactor, but they ambulate to other sites for cleaning and collecting wastes.
The other 30 subjects were working in the same centre but in places faraway from the reactor and so were considered as nonexposed control group.
Both groups were non diabetic, not hypertensive, with no history of long
term medications and not suffering from medical problems. Their ages ranged from 25-64 years.
Venous blood samples, (10 mL each) were collected from all those persons by venipuncture at 9 a.m. LH, FSH, Prolactin, Cortisol and testosterone were estimated by radioimmunoassay.
