Plain-English summary
This study looked at how much radiation exposure veterinary staff and pet owners get during x-ray procedures for small animals. Researchers used computer simulations to analyze different situations, like the angle of the x-ray beam and whether protective shields were used. They found that using a backscatter shield can greatly lower the radiation dose received by both the operator and the pet owner, highlighting the importance of following safety practices. While the radiation levels were generally below safety limits, the study emphasizes that they should still be taken seriously, especially since not using a shield during dental x-rays can increase exposure significantly. Overall, the findings stress the need for strict safety measures and proper training to keep radiation exposure as low as possible.
Abstract
The objective of the present study was to evaluate effective dose and equivalent dose values for x-ray equipment operators and the tutors of small animals during veterinary radiology procedures, using simulations via the Monte Carlo method with the heavy ion transport code system and MESH-type phantoms, as described in International Commission on Radiological Protection, Report 145. Scenarios of conventional and dental veterinary radiology were analysed, considering variations in beam incidence angle, tube voltage (kV), and the use or not of backscatter shield accessories. The results demonstrate that the use of the backscatter shield significantly reduces the doses received by the operator and the tutor, in addition to reinforcing the importance of safe practices. Adopting the appropriate parameters, kV and current-time product (mAs), adherence to radiological protection recommendations, and training professionals minimises exposures. All data reinforce the need for good practices; although the dose values are below the limits established in radiological protection, they should not be neglected. In dental radiographs, the absence of the backscatter shield can increase doses by up to 30 times. Thus, strict adherence to radiological protection standards, manufacturer's instructions, and international recommendations is essential for maintaining exposures as low as possible.
