摘要：

We report here the estimates of alpha efficiency for fine grain quartz extracted from Chinese loess using the SAR protocol. For the seven samples, the alpha-values range from 0.028 to 0.038 with an average of 0.035 +/- 0.001. The annealed quartz (450 degrees C, 45 min) has an alpha-value of 0.030 +/- 0.001 which is similar to the alpha-value of 0.029 +/- 0.001 for the non-annealed quartz extracts, suggesting that the alpha-value is independent of the quartz's thermal history for this sample. We suggest that an alpha-value of 0.035 +/- 0.003 can be adopted for quartz extracted from Chinese loess when calculating the environmental dose rate. (C) 2008 Elsevier Ltd. All rights reserved.
