تناولت هذه الدراسة ايجاد تراكيز اليورانيوم فيالدم البشري في وسط وشمال العراق (مستشفى رزكاري العام و- اربيل و مستشفى سامراء العام ومستشفى اليرموك - بغداد) للعاملين في مجال الاشعاع في قسم الاشعة وقسم التصوير بالرنين المغناطيسي وقسم التصوير الطبقي المحوري (المفراس ) ومن غير العاملين في مجال الاشعة وايجاد العلاقة بين تراكيز اليورانيوم وعدد سنوات العمل في مجال الاشعاع ونوع الجنس البشري .

This study deals with the process of finding concentrations of Uranium in human blood in central and northern Iraq (Erbil-Rizgari General hospital, Samarra-Samarra General hospital and Baghdad-Yarmouk General hospital) for workers in radiation field in X-ray, MRI (Magnetic Resonance Imaging) and CTS unit (Computed Topography Scanning), and from control group, and finding the relationship between uranium concentrations and the number of working years in the field of Radiation and type of human race. The technique of fission track analysis with CN-85 nuclear track detector was used to determine the content of uranium in blood human samples and determined the concentrations of radon in air in workplace for workers in hospitals. The results show that the highest uranium concentration in human blood of workers in X-ray unit was 2.310 ppb (male, 62 years old, 42 years work experience, living in Erbil city) and lowest concentration 1.015 ppb (female, 22 years old, 2 years work experience, and living in Erbil. while for control group, the maximum uranium concentration was 1.037 ppb (male, 28 years old, and living in Samarra) and minimum concentration was 0.574 ppb (female, 25 years old, living in Erbil). It has also been found that the uranium concentration in human blood samples of workers in the radiation field is higher than those of control group, and the uranium concentrations for male workers and control group were higher than those for female workers and control group

The radon concentration in air samples of hospitals was ranged from 32.36 Bq/m3 (MRI unit, Baghdad) to 50.424 Bq/m3 (X-ray, Samarra). the highest radon concentrations were observed in the samples in X-ray unit, with values of more than 48 Bq/m3, while the lowest readings absorbed in the samples were in MRI unit (Erbil, Baghdad), with values of less than 35 Bq/m3, X-ray unit of (Erbil, Samarra and Baghdad) had a similar value of the radon induced lung cancer risk per year in more than 20 per million persons, but all the other departments had £ 17 per million persons, the concentrations of radon in workplace for X-ray unit was higher than MRI unit and CTS unit

The Aim of the Present Work

The aim of the study is to measure the concentration of Uranium in the blood of working and non-working people in the field of radiological medical examination in Erbil, Salahddin, and Baghdad

Measurement of radon concentration in air in buildings for radiological medical examination in the same governorate

Study the relationship between the concentration of radon in the air and the concentration of uranium in the blood in the same governorate
