Evaluation of dose radiation on x-ray radiography

Abstract

Evaluated radiation dose and output of general radiographic machine on the thorax and abdomen examination. Radiation output testing on 53 radiographic machine produced 1985-2017 in East Java, Indonesia. For thorax examination, 45-89 kV, 100-200 mA, exposure time 0.01-100 s and abdominal examination, 50-89 kV, 18-320 mA, exposure time is 0.02-100 s. Tests are carried out with the Piranha X-Ray Multimeter. There are reportedly 3 of 53 radiographic machine in the thorax examination as follows: the incident air kerma (INAK), tube output, and entrance surface air kerma (ESAK) rates ranged between 0.019 - 1.604 mGy, 0.0004 - 0.0057 mGy/mAs, and 0.024 - 2.101 mGy. While on abdominal examination, the INAK, tube output, and ESAK rates ranged between 0.009 - 2.710 mGy, 0.014 - 0.072 mGy/mAs, and 0.013 - 3.660 mGy., From data with various brands, general radiographic machine in East Java, for Thorax and Abdomen examination INAK values are below 1,604 mGy, 2,710 mGy, values are below 0.0057 mGy / mAs, 0.072 mGy / mAs, and ESAK values are below 2,101 mGy, 2,710 mGy and still within the limits permitted by the BAPETEN regulation in Indonesia.
