Resumo

Porosity in ceramic membranes supports of Titanium dioxides was investigated by gamma spectroscopy. This technique is based on the attenuation that a beam of gamma radiation suffers when crossing a material. Linear Atenuation coefficient of the material under analysis was calculated to evaluate porosity. Results showed that the porosity by the gamma-ray transmission method are higher than the values obtained by the Archimedes and geometric due to  higher sensitivity of the gamma-ray transmission method
