Análise das propriedades físicas em estrutura do tecido ósseo de eqüinos

This project has several objectives: To determine medium values and variations of the density, porosity, humidity, shrinkage volume and the coefficient of mass attenuation of gamma radiation of 59,6 keV of the radioisotope 241Am, using samples of equine radio, in growth and adult. The samples of bones were supplied by the Department of Pathology of University of Veterinary Medicine and Zootechnics - UNESP campus Botucatu. Bones of the paws front left of two males were used. Of each bone ten samples were removed. Those samples were prepared to just obtain compact bony fabric, being submitted to the rehearsal of determination of the density by the immersion method in water and determination of the coefficient attenuation lineal for the method of attenuation of the radiation of the 241Am, also obtaining your humidity content. Still, they were obtained new samples starting from the ground samples and verified the density of the particles present in that, obtaining the medium value of the coefficient of mass attenuation. The results showed the medium values and significant statistical variations of the density, porosity, humidity, shrinkage volume and coefficient of mass attenuation of gamma radiation of 59, 6 keV of the radioisotope 241Am in the samples, establishing some relationships between of the certain physical parameters with biological aspects and possible existent influences between them
