In this study, EPMA and LA-ICP-MS were used to determine the major and trace element concentrations, respectively, of apatites from Transhimalayan granitoids. The results indicate that F, Mn, Sr and REEs in apatites generally show good correlations with compositions of their host magmas and thus have high potential to be utilized as petrogenetic tracers. More specifically, F and Mn contents in apatites are covariant with the aluminosity of the host rocks so that can be used as an indicator for magma differentiation. Combining with Sr and REE data, which show significant variations in apatites from different rock types, these elements may be furthermore used to construct "discrimination diagrams" for more detailed investigations of complex petrogenetic processes such as magma mixing and compositional heterogeneity.

The thermoluminescent dosimeters are widely used for measuring the radiation dose. However, the luminescence centers of thermoluminescent dosimeter are disappeared by reading process, and then repetition of measurement is impossible.

The aims of this study are to develop and characterize the radiophotoluminescent glass dosimeter and measure the clinical radiation dose using Dose Ace system.
