METHOD OF MAKING FIBRE SCINTILLATORS Russian patent published in 2009 - IPC G01T1/00 

FIELD: physics; measurement.

SUBSTANCE: invention relates to scintillation materials, specifically to fibre scintillators, meant for measuring ionising radiation. The method of making fibre scintillators involves heating scintillator material with subsequent formation of a fibre structure, and is characterised by that the scintillator material is heated to 170-180°C at pressure 120-140 kg/cm². The fibre is formed using an extrusion method at a rate of 1.5-2.0 m/hr. The scintillator material used is in form of metal halides with the following ratio of ingredients, wt %: silver chloride 18.0-20.0; silver bromide 79.4-80.5; silver iodide 0.1-0.5; thallium (I) iodide 0.5-1.0.

EFFECT: obtaining TII doped, flexible and long fibre scintillators with fluorescence spectrum maximum at 550 nm wavelength using a method of extrusion from crystals based on solid solutions of silver halides.
