Cuantificación de radiación dispersa en ambientes contiguos durante el uso de equipos portátiles de radiología intraoral

Abstract

The Portable Equipments of Dental Radiology are a technological innovation that has brought great changes in the clinical practice, especially in the máxi of endodontics where they are used routinely. They produce ionizing radiation to both patient and operator; this radiation interacts with the living matter and can produce harmful effects. The harmful effects maximum ó the absorbed dose, time and type of material exposed. This analytical observational study of cross section quantifies the level of scattered radiation in adjacent environments of these equipments (Nomad Pro, Port X-II, DX 3000, Prox) for this purpose it was used a Geiger radiation meter equipment, based in two situations: backscatter and two meters away from the portable dental radiology. It was made 10 shots by each situation, programming the equipments for a radiograph of a molar adult and quantified the radiation absorbed by the operator and occupational support staff. The Results showed that the Nomad Pro obtained the lowest radiation under the two situations being 0,011 mSv/hr the value for the operator status and 0.013 mSv/hr for the situation of two meters. As maximums ón of the máximum, even though none of the tested equipments were above to the allowed annually limit (20mSv / year), nothing prevents the use of radiological protection to keep the ALARA principle.
