In order to increase the contrast and to improve the imaging capabilities of a Gamma-ray Backscattering device some changes are proposed with the aim of achieving a reduction of the intrinsic noise of the device. Simulated results suggest that the shielding system proposed, in addition to the use of a 68 Ge -γ ray source, produce a considerable reduction of the intrinsic noise of the device.
Con el fin de disminuir el contraste y mejorar las capacidades de un dispositivo de formación de imágenes por retrodispersión de rayos gamma, se proponen algunos cambios dirigidos a disminuir el ruido intrı́nseco del aparato. Los resultados obtenidos con la simulación, sugieren que con el uso del sistema de blindaje propuesto, junto al uso de una fuente de radiación de 68 Ge, se logra disminuir considerablemente el ruido intrı́nseco del dispositivo.
