Abstract
There are many changes that have affected badly the environment and
people’s life in Iraq during the last two decades as a result of wars and suspected
used of prohibited weapons and what ways these reveal dangerous diseases. The
objectives of the present work was to measure the uranium concentration in urine
taken from workers in factories and hospitals by using Fission Track Analysis (FTA)
technique, analyze the specific activities of radionuclides analysis in soil using high
purity germanium (HPGe) detector, and determining radon concentration in air using
Nuclear Track Detectors (NTDs) LR-115 type II. Also, Alphaguard water borne
radon detector was used to determine radon concentration in water samples. Air,
water and soil samples were taken from factories and hospitals in selected regions of
Iraq after the 2003 Gulf war. The results shown that the highest uranium
concentration was 3.39±0.43 μg/L for urine samples of workers from the Phosphate
factory and the lowest uranium concentration was 1.31±0.24 μg/L for X-ray workers
in hospitals. The uranium concentration in the urine samples increases with number
of working years. The uranium concentration in urine samples of male, sick, addicted
and smoking workers are higher than female, healthy, non addicted and non smoking
workers, respectively. Soil samples from the Phosphate factory have the maximum
values of Raeq, Hin, Hex, ADRA, and the annual effective indoor and outdoor doses
were 744.71 Bq/kg, 4.07, 2.06, 353.39 nGy/h, 1.734 and 0.433, respectively
compared to other factories and hospitals.
