CONTAINED IN VOL. 03.03, 2017 Describes an empirical technique for the measurement of the effective collimation ratio, L/D, of neutron radiography beams.

1.1This test method defines an empirical technique for the measurement of the effective collimation ratio, L/D, of neutron radiography beams. The technique is based upon analysis of a neutron radiographic image and is independent of measurements and calculations based on physical dimensions of the collimator system. The values derived by this technique should be more accurate than those based on physical measurements, particularly for poorly defined apertures.
