Efficacy of Shields Against the Backscatter Radiation of Portable X-ray Units
Abstract
The NOMAD and NOMAD Pro are handheld X-ray units that have fixed shields against backscatter radiation. The DEXCO ADX4000W and DEXCO DX3000 include these shields as optional, detachable accessories. For this study, the objective of which was to clarify the characteristics of Portable X-ray Units, we evaluated the characteristics of output and measured the changes in air kerma of stray radiation from four portable intraoral X-ray units with/without a shield.
