| Abstract | ||
| Estimation of radiation absorbed dose in long term X-ray examination (Fluoroscopy) that the patient subjected to are of great value in the field of radiation protection. The aim of this project is to determine the amount of air kerma dose in air that can reflects the amount of the risk that the patient subjected to, also to calculate the dose area products (mGy/cm2)and do comparison between EASK and DAP. The parameters that which are involved in this project are X-ray tube current (mA) , exposure time (sec.), focal film distance(FFD) and focal skin distance (FSD) in cm.ESAK and DAP are calculated using mathematical equation for different fluoroscopic examination of different patients. 35 cases were involved in this projects [15 male and 20 female].The results show that the ESAK are ranged between 54.438mGy and 120.27 mGy and the DAP ranged from 491.847 mGy.cm2 to 1086.639 mGy.cm2 . | ||
