DESCRIPTION:Speakers: Cristina Cabo Landeira (UIniversidade de Santiago de
  Compostela)\nConventional X-ray radiography is the current standard for i
 ndustrial non-destructive testing of metallic parts. However\, some limita
 tions arise due to the low penetration depth of X-rays for certain materia
 ls or their thickness. This is the case for metal additive manufacturing\,
  where quality control and internal inspection are critical in most applic
 ations. In this paper we report the use of a $^{137}$Cs gamma source ($\\s
 im$180 MBq) and a $^{60}$Co gamma irradiator ($\\sim$47 TBq) for gamma rad
 iography and tomography of steel samples from additive manufacturing. A si
 mple experimental device composed of a scintillating screen and a frame-ba
 sed camera was used to digitally capture the sample images. Internal detai
 ls were observed with a spatial resolution of 1 -- 3 mm. The same imaging 
 device was adapted and utilized for neutron radiography using thermal neut
 rons from a particle accelerator with similar results. This demonstrates t
 he potential flexibility of the device for different source types in a por
 table and cost-effective system for non-destructive tests.\n\nhttps://indi
