Abstract

In radiography, a dose to patients primarily depends on the Entrance Surface Dose (ESD) and the sensitivity of organs which are irradiated during treatment plan. The main goal of this study is to look into the patient’s dose to assess ESD and ED for patients in digital diagnostic radiography examinations for the optimization of radiation protection of the patients who are exposed to radiation dose thereby facing the increasing probability of fatal cancer risk and other biological effects. Patients dosimetry carried out on 15 adult patients (Male-4 and Female-11) of age 20 to 69 years. The IAEA TRS No. 457 dosimetry protocol was followed in accordance with non-invasive kV-meter, DIAVOLT UNIVERSAL T43014-001400, locating at 100 cm from focus to surface distance for measurement of radiological parameters such as kVp and mAs. The ESD has a wide range from 0.05mGy to 0.35 mGy for chest even for the same examination carried out on the patients of different age and gender and the corresponding effective dose lies from 0.01 to 0.04 mSv, additionally, in other parts like L-spine AP, Lat and in foot ESDs are 1.24 mGy, 2.06 mGy and 0.07 mGy respectively with their corresponding EDs are 0.13 mSv, 0.05 mSv and 0.0003 mSv. The ESDs and EDs reported in this study are generally lower than the doses published in literatures.
