TRANSPARENT TISSUE-EQUIVALENT DETECTOR OF RADIATION BASED ON LiBO FOR THERMALLY OR OPTICALLY STIMULATED LUMINESCENT DOSIMETRY AND METHOD OF ITS MANUFACTURING Russian patent published in 2014 - IPC G01T1/11 C09K11/59 C09K11/58 C09K11/63 C09K11/55 

FIELD: measurement equipment.

SUBSTANCE: invention relates to chemical industry and dosimetry of radiation. For production of a transparent tissue-equivalent detector of radiation based on Li₂B₄O₇ they perform the following stages: a) components of initial reagent of the detector are mixed, including deionised water, boric acid H₃BO₃, admixture Mn and binding material silicon dioxide SiO₂; b) mixture temperature is increased to 75-85°C, lithium carbonate Li₂CO₃ is added, and the secondary admixture Be²⁺, which does not reduce transparency of the detector in the range of wave lengths 320-750 nm; c) ageing, drying and preliminary annealing is made on the produced initial reagent; d) initial reagent is ground, polished and sifted; e) moulded under pressure; f) the moulded bodies of the detector are sintered.

EFFECT: produced detector has suppressed low-temperature maximum and is transparent both for stimulating light and outlet luminescence.
