Apstrakt

This International Standard defines an empirical technique for the measurement of the effective collimation ratio
and effective L/D of thermal neutron radiography beams for values between 20 and 1 000. 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 device described in this International Standard has been
developed and tested using Gd foil converters with a single emulsion, high resolution film in vacuum cassettes.
