METHOD OF PRODUCING PLASTIC SCINTILLATORS BASED ON POLYSTYRENE GRANULES Russian patent published in 2017 - IPC G01T1/20 

FIELD: measuring equipment.

SUBSTANCE: invention relates to detecting ionizing radiations and can be used for making cheap scintillation detectors in the widest range of dimensions and thickness. Manufacturing method of plastic scintillators based on polystyrene granules involves drying and powdering the granules with scintillation additives with subsequent melting of the powdered granules, herewith melting of the granules is performed in placed in a vacuum furnace open forms determining the shape of scintillation articles at evacuation and filling the working volume of the furnace with an inert gas. All surfaces of the scintillators made as per the claimed method, except the open surface, are cast copies of surfaces of the melting formes material – polished stainless steel, i.e. mirror ones. Open surface when performing the technical regulations is also a mirror and in most cases does not require additional machining.

EFFECT: possibility of production of scintillation strips of significant thickness, which do not require additional machining.
