    "ADIATION DOSE RISKS ESTIMATIONS ASSOCIATED WITH COMMON CT EXAMINATIONS OF CHEST IN SOME OF IRAQI GOVERNATES Iskander Ali Aziz1 , Aysar Sabah Keiteb2 , Amal Faisal Jaffar 3 1Diyala Health Department / Radiology Unit / Diyala, Iraq 2Middle Technical University (MTU), College of Health and Medical Technology, Dept. Radiology Technology / Baghdad, Iraq 3Middle Technical University (MTU), Institute of Medical Technology - Baghdad e-mail: draysaralnidawi@mtu.edu.iq ABSTRACT Purpose: To estimate how much radiation exposure can be associated with CT examinations of the chest. The study is associated with that most commonly performed in Bagdad, Diyala, and Babylon region hospitals, in order to assess the radiation dose and to determine, whether it is within the permissible levels set buy CT scan machine manufacturers, and to estimate variation across study types, patients, and Hospitals, and to find out the best type of CT device that gives the least dose exposure of radiation among the three used machines. Methods: This study was conducted on 147 consecutive patients (75 males and 72 female) at an age ranged 2-90 years cases, were examined by three CT scan companies; (Toshiba, Siemens, and Philips) The examinations were conducted for the chest in each device. Dose information were taken from the protocols designated for each machine, which is the calculation of DLP, CTDI of each CT machine. And comparing it with global doses to know the dose for each device. Also, use the dosing meter to examine the dose directly for each patient, which is a type of Gama Scout. It was also compared to the global doses of Table 103 for the year 2007. Results: The DLP was compared with each device data, after converting the recorded dose to millisieverts for each device to identify the average dose, the following values were obtained, The Toshiba, Philips and Siemens, 10.046 mSv, 9.814 mSv, 5.171mSv respectively. Conclusions: The results of the study showed that; amount of radiation exposure was higher than the permissible limit according to the radiation protection law in 3 governorates for the chest examination, the study also found a disparity between the devices, and Siemens CT machines, found to be the lowest in terms of dose exposure limits.
