1.	In radiography, the penetration of rays is much easier with the less density of metal or casting.(a) True(b) FalseI got this question during an interview for a job.This key question is from Non Destructive Testing in section Inspection Testing in Foundries of Casting-Forming-Welding I
Answer» Correct ANSWER is (a) True For explanation I would say: The ability of rays to penetrate through the metal mainly DEPENDS on the density of metal and they can penetrate more easily where LESS density of metal is present and it LEADS to the formation of shadow picture on the film. And any defects in the CASTING can easily be identified from the shadow picture.
