Resumo

This paper presents a methodology for the determination of the linear attenuation coefficient. In order to validate the alignment and collimation of the geometry of the measurement for the calculation of the linear attenuation coefficient, a study was carried out with a reference material, a tantalum sheet with purity of 99.9% and thickness of 0.010 mm, supplied and measured by GoodFellow. The linear attenuation coefficient found experimentally was compared with the value of the literature.
