WORKING MEDIUM FOR THERMOLUMINESCENT DETECTOR OF IONISING RADIATION Russian patent published in 2011 - IPC G01T1/11 

FIELD: physics.

SUBSTANCE: working medium can be used to make a thermoluminescent detector of ionising radiation used in individual dosimetry to determine the dose absorbed by personnel; to determine the dose absorbed by patients during X-ray diagnostics and therapy; to determine the dose absorbed in the radiation field of high-dose process installations. The working medium for thermoluminescent detectors of ionising radiation contain nano-dispersed diamond powder with particle size of approximately 5 nm, powder of SiO₂-based material ground to particle size smaller than 0.08 mm and silicate glue as binder for the two materials. The composite working medium is prepared by mixing SiO₂ and ultradispersed diamond in the following ratio, wt %: ultradispersed diamond powder with particle size of approximately 5 nm 25-65, SiO₂ 25-65, silicate glue - the rest.

EFFECT: wide range of detected ionising radiation doses of the working medium.
