In this study, we assess the benefits and drawbacks of different dosimeters by dividingthe scattered rays generated while manipulating the distance, kVp, and mAs into Ion chamber,Piranha, TLD, PLD, and OSLD dosimeters using a diagnostic X-ray unit that is widely used inthe general imaging field. We then measured, compared, and analyzed the results. We determinedthe direction and energy dependence according to the sensitivities of dosimeters. Throughanalyzing the difference between dosimeters based on distance, we discovered that OSLD hadthe best sensitivity, and the PLD had the poorest sensitivity to a statistically significant degree. In the kVp fixed mAs change, when compared overall, the ion chamber and PLD had thelowest energy dependence, and the OSLD had the highest energy dependence. In the mAs fixedkVp change, when compared overall, the energy dependence of TLD was the lowest, and theenergy dependence of OSLD was the highest. Based on our results, we determined that the idealdosimeters were OSLD for sensitivity, TLD for kVp change in energy in dependence, and Ionchamber and PLD for mAs change.
Abstract

We then measured, compared, and analyzed the results. We determinedthe direction and energy dependence according to the sensitivities of dosimeters. Throughanalyzing the difference between dosimeters based on distance, we discovered that OSLD hadthe best sensitivity, and the PLD had the poorest sensitivity to a statistically significant degree. In the kVp fixed mAs change, when compared overall, the ion chamber and PLD had thelowest energy dependence, and the OSLD had the highest energy dependence. In the mAs fixedkVp change, when compared overall, the energy dependence of TLD was the lowest, and theenergy dependence of OSLD was the highest.
