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 device includes a unit for heating the said detector, as well as a unit for picking up thermoluminescence of this detector. The output of the unit for picking up thermoluminescence is connected to the input of the unit for evaluating the absorbed dose from parametres of the obtained thermoluminescence curve. The essence of the invention lies in that, the said unit for picking up wavelengths is made with characteristics which provide a function for picking up wavelengths only in the range from 500 to 570 nm. Further, the device is distinguished by that, the said unit for picking up wavelengths of the detected thermoluminescence is made with characteristics which provides a function for picking up wavelengths in any subrange of the said wavelength range, with width of not more than 30 nm, particularly 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 -radiation. ^ 3 dwg |
