Portable X-Ray Devices: Loosing Border Between Controlled and Supervised Areas

Abstract

The introduction of portable hand-held X-ray devices opened a new chapter in dental radiology. The strict border between the controlled and supervised areas ceases to exist. The aim of this paper is to measure the dose rate around a portable dental X-ray device, as well as to provide spatial distribution of the ambient dose equivalent of scattered radiation. Results also include measurements of X-ray tube voltage, incidence air kerma, exposure time, half-value layer and total filtration according to the international standard IEC 61223-3-2:2015 Evaluation and routine testing in medical imaging departments for the quality control of dental X-ray devices. Measured values of incidence air kerma indicate the values of the patient doses which are much lower than existing national diagnostic reference values.
