Spectral characteristics of six phosphors used in thermoluminescence dosimetry

Abstract

Thermoluminescence emission spectra of six phosphors commonly used for TL dosimetry are presented at doses between 15 mGy and 1 Gy. The use of a Fourier transform spectrometer has made it possible to obtain spectra at doses considerably lower than those for spectra previously reported. The spectra are in the form of isometric plots of intensity versus temperature and wavelength. They are compared with previous observations at higher doses with comments on the mechanisms involved.
