摘要：

Standard thermoluminescent (TL) detectors, owing to their relatively large thickness, may seriously underestimate personal skin doses which are defined at the depth of 7 mg cm(-2). New TL ultra-thin, LiF:Mg,Cu,P-based detectors have been developed at the Institute of Nuclear Physics to fulfil simultaneously the requirements of flat energy response for beta rays and the ability to measure low beta ray doses. In our detectors a thin layer of MCP phosphor is bonded with a thick base of undoped LiF. We assess the effective thickness of this detector to be 8.5 mg cm(-2). Tests of these detectors exposed with and without covering foil to Pm-147, Tl-204 and Sr-90/Y-90 calibrated beta fields indicate that our detectors feature an essentially hat energy response and good angular characteristics. The sensitivity of our detectors permits doses in the microsievert range to be measured reliably.
