Densitometric analysis of Radiation Absorbed Dose to Patients Undergoing Chest X-ray Examination in a Government Owned Hospital, Kano-Nigeria

Chest X-ray is one the most frequently required diagnostic procedures used in clinical practice to produce an image of organs, tissues and bones body with a significant impact on collective dose. However, radiation dose received by patients from this procedure likely show large variations within among radiodiagnostic centres. This could be traced lack imaging protocols local or national reference levels. Although doses resulting are usually measured terms effective entrance surface using electronic personal dosimeter (EPD), pocket dosimeter, thermoluminescent (TLD), film badges, optically stimulated luminescent (OSLD). For sake protection, densitometric analysis was evaluate medical exposure for chest radiographs determine point optical densitometer; PTW-DensiX range 0 4.0 density. The hospital where study carried out Kano State. A total sixty (60) radiographic films were collected density each five times at different spots. mean obtained converted mathematical relation absorbed cGy. results that 0.78 ± 0.13 cGy low compared previous held hospitals Osun Also, when excess 0.10 Gy recommended International Commission Radiological Protection, it evident radiological especially as relates practice.
