摘要

Dose-assessment for natural radiation has been investigated in regard to the high background radiation areas (HBRA) around the world. Natural SiO_2 crystals collected in the HBRA which exhibit TL is expected to be usable for dosimetry of the radiations from natural sources. However, the TL mechanism has not yet been well explained. In this paper, TL spectra were examined on natural SiO_2 and synthesized SiO_2 doped with Al~(3+) and/or Eu~(3+). As the results, it is expected that we could establish more quantitative TL dosimetry on HBRA using natural SiO_2 crystals by estimating quantum efficiency on each TL of Eu~(3+).
