Neutron imaging is a nondestructive testing method you might have heard of before, but probably haven’t had a chance to use. Despite being a powerful method for inspecting components in many industries, only a small community of NDT professionals are truly aware of neutron radiography, or N-ray.Are you a part of this small community? Take our quiz to find out: 1. Neutron imaging is more useful than X-ray imaging for… Detecting internal flaws in cast parts Identifying bonding flaws in adhesives Detecting and identifying the positions of o-rings, seals, lubricants, and adhesives inside complex assemblies All of the above 2. Neutrons, unlike X-rays, are better for penetrating… Dense materials Light materials Water Plastics 3. Neutron radiation interacts most strongly with… The electron cloud The atomic nucleus Photons Other neutrons 4. True or false: Neutron imaging can only be done with a nuclear reactor. True False 5. True or false: Neutron imaging can be used in field work. True False 6. Neutron radiation is produced by: Fission of uranium Fusion of deuterium with tritium Fusion of deuterium with deuterium All of the above 7. True or false: In neutron imaging, the collimator focuses the neutron beam using electromagnets. True False 8. Neutron imaging has not often been used as a nondestructive testing tool because… Neutrons are actually very destructive Neutron imaging has only a few specific uses Current imaging facilities are difficult to access The objects being imaged remain “hot” for too long 9. Objects exposed to neutron radiation remain “hot” for how long? About twelve hours Roughly 66 hours One week 700 thousand years 10. What is the ASTM standard for neutron imaging? ASTM E1931 ASTM E545 and E748 ASTM E1742 and E1742M ASTM E1032All done?
