Comparison of neutron radiography with other nondestructive methods

The development and quality insurance of high tech products of industry needs the application of various nondestructive testing methods. We have applied neutron-, gamma-, and X-ray radiography, vibration diagnostics, acoustic emission, and neutron diffraction for testing various industrial products. Here, we present some of our recent results obtained on absorption-type refrigerators, on automotive Visco clutches and on high temperature thermostats.
