Participation between radiographers and medical physicists is needed in optimizing efforts to control the selection of exposure factors by the required clinical radiographic examination. This research is descriptive quantitative by analyzing of exposure index results used in the chest PA examination as an effort to optimizing radiation dose. Also, statistical analysis was carried out to determine the relationship between exposure and the exposure factor using the Spearman test. Results the Spearman test results for underexposure to kV 0.207, and mAs 0.012, meanwhile for overexposed to kV -0.283 and mAs 0.166, the radiographer can make efforts to optimize radiographic examinations by considering the optimal selection of exposure factor parameters which can use a combination of exposure index by assessing the deviation index indicator and maximizing use post-processing or windowing to improve image quality.
