    Abstract

    Dosimetric properties of two different types of thin TL detectors, designed to measure personal doses at a depth of 7 mg.cm(-2) in tissue, have been compared. At Riso National Laboratory detectors were prepared by fixing LiF:Mg,Cu,P GR-200 thin detectors to 0.7 mm thick Al pieces. At the Institute of Nuclear Physics, a thin layer of LiF:Mg,Cup phosphor of effective thickness 8.5 mg.cm(-2) was sintered to a base of undoped LiF. Beta energy and angular response, detection threshold, stability, etc. were investigated for the two detector types. Results show that both detectors possess good energy characteristic and that their sensitivity is sufficient to measure doses below 100 mu Gy reliably. Hence, they are suitable for practical applications in extremity dosimetry.
