FIELD: chemistry.
SUBSTANCE: invention relates to nondestructive analysis of radiating objects using neutron imaging. Device designed to be used for neutron imaging immersed in a medium containing specimens to be analysed, comprises first converter (C1) comprising a first material capable of converting thermal neutron radiation into remnant beta radiation by its neutron activation; and second converter (C2) comprising a second material capable of absorbing thermal neutron radiation by capture and capable of converting remnant beta radiation into light radiation, said second converter being in contact with said first converter; support (S3) comprising hydrogenated species on which said second converter is positioned, said support being transparent to said light radiation.
EFFECT: technical result is high spatial resolution of an image obtained by neutron imaging.
