The sensitivity vs. dose characteristics of two TL readers (Harshaw 2000 A + B and NHZ-203C) was compared both in the range of small doses (10 microGy to 100 mGy) as well as in the radiation therapy level by using individually calibrated LiF:Mg, Ti detectors manufactured in Poland. The performance of both systems can be predicted by a three parameter theoretical model. The very good reproducibility of the NHZ-203C reader (sigma/D = 0.6%) is important in radiation therapy while the high sensitivity (the lowest detectable dose limit = 3 S.D. of the background = 27 microGy) is useful for radiation protection measurements.
使用波兰制造的经过单独校准的LiF:Mg, Ti探测器，在小剂量范围（10微戈瑞至100毫戈瑞）以及放射治疗剂量水平下，比较了两台热释光（TL）读数器（Harshaw 2000 A + B和NHZ - 203C）的灵敏度与剂量特性。两个系统的性能可以通过一个三参数理论模型来预测。NHZ - 203C读数器具有非常好的重现性（标准差/剂量=0.6%），这在放射治疗中很重要，而其高灵敏度（最低可探测剂量限值=背景值的3倍标准差=27微戈瑞）则对辐射防护测量很有用。
