ENTC 402 radiography (NDT2)fully solved 2023 verified to pass

ENTC 402 radiography (NDT2)Undercut is the loss of resolution at a sharp, thickness transition area due to: - correct answer Scattering within the film Bremsstrahlung production of x-rays produces radiation that is composed of - correct answer A continuous spectrum of energies over some range X- rat generators produce radiation through - correct answer Bremsstrahlung process and k-shell emission process (A&B) Stationary lab or shop x-rays systems usually rely on what to limit the exposure to the radiation? - correct answer Shielding Manmade sources of radioactive sources are produced by - correct answer Introducing an extra neuron to the atoms of the source material The main advantage of real time radiography over film is - correct answer Inspection can be performed more rapidly Two of the more common industrial gamma ray sources are - correct answer Cobalt 60 and iridium 192 Which of the following does not affect radiographic contrast - correct answer The level of current used for the exposure Film contrast is determined by - correct answer The type of film used and the process by which the film was developed (a&b) Lowering the energy of the radiation used to produce a radiograph will generally result in - correct answer Less latitude/high contrast sensitivity/a longer exposure time (all of the above) When flaws are in unknown locations, radiography is vest suited for detection of - correct answer Volumetric defects such as porosity Image quality indicators (IQIs) procidet - correct answer Resolution and contrast senstivity Which of the following is not a strength of radiographic inspection - correct answer Access to both sides if the test sample is required Image quality indicators are usually placed - correct answer On the front side of the test component in an area of similar thickness to the primary area of interest
