FLECHAS, David  and  CRISTANCHO, Fernando. INTRINSIC NOISE REDUCTION OF A GAMMA-RAY BACKSCATTERING IMAGING DEVICE. Momento [online]. 2021, n.63, pp.12-21.  Epub Aug 21, 2021. ISSN 0121-4470.  https://doi.org/10.15446/mo.n63.93837.

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 68Ge γ-ray source, produce a considerable reduction of the intrinsic noise of the device.

Keywords : Gamma backscattering; imaging device; noise reduction.
