LiF:Mg,Ti thermoluminescent dosimeters (TLD's) were obtained from three manufacturers with the specification that they all lie within +/- 5% of the mean. All were chips of size 3 mm x 3 mm x 1 mm. The three sample groups were compared on the basis of their energy response, linearity of the thermoluminescent (TL) response with increasing exposure, sensitivity, and reproducibility of TL response. All TLD groups showed similar characteristics in energy response and linearity. This is to be expected since the base material and dopants were the same. However, the sensitivity varied among the three groups by as much as 40% and reproducibility measurements gave standard deviations ranging from 7% to 14% among the groups. Annealing procedures were identical in all cases, as were irradiation and readout conditions.
从三家制造商处获得了LiF:Mg,Ti热释光剂量计（TLD），其规格要求它们都在平均值的±5%范围内。所有剂量计都是尺寸为3毫米×3毫米×1毫米的芯片。根据能量响应、热释光（TL）响应随照射增加的线性度、灵敏度以及TL响应的可重复性，对这三个样本组进行了比较。所有TLD组在能量响应和线性度方面表现出相似的特性。鉴于基础材料和掺杂剂相同，这是可以预料的。然而，三组之间的灵敏度差异高达40%，并且可重复性测量得出的组间标准偏差在7%至14%之间。所有情况下的退火程序相同，照射和读出条件也相同。
