METHOD OF DETERMINING ABSORBED DOSE OF BETA RADIATION IN THERMOLUMINESCENT DETECTOR BASED ON ANION-DEFECT MONOCRYSTAL OF ALUMINIUM OXIDE Russian patent published in 2010 - IPC G01T1/11 

FIELD: nuclear physics.

SUBSTANCE: invention can be used in personal dosimetry, in monitoring radiation environment, in archeological and geological dating and in accident dosimetry. The method involves heating a detector while simultaneously measuring intensity of thermoluminescence in the visible spectrum and subsequent evaluation of the absorbed dose from parametres of the obtained thermoluminescence curve. The essence of the invention lies in that, intensity of thermoluminescence is measured only within the 500 to 570 nm wavelength range. Further, the method is distinguished by that, measurements are taken in any wavelength subrange of the said range, with width of not more than 30 nm, for example in the subrange from 520 nm to 550 nm.

EFFECT: increased upper limit of the linear range of the dose characteristic and increased accuracy of evaluating absorbed dose of β-radiation.
