Understanding Neutron Radiography

Some desirable characteristics of a reactor for radiography are low cost per
neutron; high available thermal neutron flux for beam extraction; some
capability for beam tailoring; small physical size; and low power output. The
two most formidable problems associated with procuring a special purpose
reactor are overall cost, plus the need to satisfy the requirements and
regulations imposed by various regulatory agencies. The capital cost of a
reactor facility is high compared to most other pieces of nondestructive test
equipment. Even a small reactor would require several trained people to
operate it and perform the radiography.
