dc.description.abstractAim: The aim of this study is to compare the absorption ability of two lead-free aprons with a lead apron. Method: The absorption ability of three aprons was measured and compared; Opaque Fusion 0.35 mm (OpaqFu) bilayer apron containing bismuth and antimony, No Lead 0.35 mm (NoLead) one-layer apron containing antimony, and a lead apron. The measurements were repeated with and without each of the aprons present in both primary and scattered beams. The selected tube voltages were between 60 and 113 kVp with constant mAs, a fixed field size, and fixed source-to-object distance. Results: No significant difference in absorption ability of the two lead-free aprons compared with that of the lead apron was observed when the dose was measured in the primary beam. When measurements were performed in the scatter radiation field, the absorption ability of the OpaqFu apron was 1.3 times higher than that of NoLead apron and nearly equal to the absorption ability of the lead apron. An increase in the difference between the OpaqFu and NoLead aprons was observed for the tube energies higher than 100 kVp in favor of OpaqFu apron. Conclusion: It is safe to use the lead-free aprons that were tested in this study in a clinical environment for the tube energy range of 60 kVp–113 kVp.pt_PT
dc.description.abstractRÉSUMÉ - But: Comparer la capacité d'absorption de deux tabliers sans plomb avec un tablier de plomb. Méthodologie: Mesurer et comparer la capacité d'absorption de trois tabliers: un tablier bicouche OpaqFu contenant du bismuth et de l'antimoine, un tablier monocouche NoLead contenant de l'antimoine et un tablier au plomb. Les mesures ont été répétées avec et sans que chaque tablier soit présent dans des faisceaux primaire et diffusé. Les tensions de tube se situaient entre 60 et 113 kVp à mA constant, une taille de champ fixe et une distance source-objet fixe. Résultats: Aucune différence significative n'a été constatée dans la capacité d'absorption des deux tabliers sans plomb comparativement au tablier de plomb lorsque la dose a été mesurée dans le faisceau primaire. Lorsque les mesures ont été prises dans le champ de rayonnement diffusé, la capacité d'absorption du tablier OpaqFu était de 1,3 fois supérieure à celle du tablier NoLead apron et presque égale à celle du tablier de plomb. Une augmentation de l’écart entre les tabliers OpaqFu et NoLead a été observée pour les énergies de tube supérieures à 100 kVp en faveur du tablier OpaqFu. Conclusion: Il est sécuritaire d'utiliser les tabliers testés dans l’étude dans l'environnement clinique pour les valeurs d’énergie comprises entre 60 et 113 kVp.pt_PT
