DETECTOR OF PENETRATING RADIATIONS Russian patent published in 2006 - IPC G01T1/20 G01N23/02 

FIELD: technology for non-destructive control of materials and goods by radiation methods, possible use for detection of flaws in industrial and field situations, and also for detection of hazardous substances at control posts, railroad stations, in airports and customs.

SUBSTANCE: in detector, luminescent optically transparent transforming screen is used in form of plate, on the surface of which condenser is located. Radiation registration system contains deflecting mirror and serially positioned inlet projection objective, image amplifier, scaling objective and charge connection device matrix. Transformer screen is made extensive along radiation expansion direction. Plate may be made of luminescent polystyrene or of material, sensitive to roentgen and gamma radiations, or of luminescent polystyrene with admixture of boron. Condenser may be made with three lenses.

EFFECT: increased efficiency and spatial resolution not only in parallel, but also in conical beam, expanded functional capabilities of detector, registration of various types of penetrating radiation: fast neutrons, thermal neutrons, roentgen and gamma rays.
