APPARATUS FOR DETERMINING ABSORBED DOSE OF β-RADIATION IN SOLID-STATE THERMOLUMINESCENT DETECTOR Russian patent published in 2013 - IPC G01T1/11 

FIELD: physics.

SUBSTANCE: apparatus for determining absorbed dose of ionising β-radiation in a thermoluminescent detector has a unit for heating said detector and a unit for detecting thermoluminescence of said detector; the output of the unit for detecting thermoluminescence is connected to the input of a unit for estimating absorbed dose from parameters of the obtained thermoluminescence curve, wherein between the unit for detecting thermoluminescence and the thermoluminescent detector on the propagation path of light from said detector there is a unit for selecting wavelengths of the detected thermoluminescence, wherein the solid-state thermoluminescent detector used is monocrystalline aluminium nitride AlN, the unit for selecting wavelengths of the detected thermoluminescence has characteristics which provide a wavelength selection function only within the range from 340 to 380 nm.

EFFECT: wider range of linearity of the dose curve, high accuracy of estimating absorbed dose of β-radiation, wider field of use of the apparatus, wider range of apparatus of determining absorbed dose of ionising β-radiation in a solid-state thermoluminescent detector.
