Neutron radiographic characteristics of MA-ND type (allyl-diglycol-carbonate) nuclear track detectors

Abstract Neutron radiographic properties of recently developed new nuclear track detectors (MA-ND/α, MA-ND/p and MA-ND/p1), manufactured from allyl diglycol carbonate, were studied. It was found that the quality of radiographic image has an optimum at a removed layer thickness of about 0.8μm. The image obtained under this condition is characterized by high detection sensitivity to neutrons (∼8·10 -3 tracks/n th when using B converter) and by excellent inherent unsharpness (∼5μm) as well as high image contrast (maximum value of net optical density is ∼1.4).
