Abstract
Intrinsic photostimulated thermoluminescence (PSTL) in the range 200-320 nm and radiation sensitized PSTL for 200-425 nm have been studied in Al2O3 (Si, Ti) phosphor. Causes of the effects found, partly attributed to phototransfer of electrons, are described. Linearity in the intrinsic and radiation sensitized response of the 280 degrees C TL peak for both pellet and powder forms has been studied with regard to ultraviolet dosimetry over the range 10-2 to 5*104 mJ cm-2. Details of the use of powder and pellet forms for dosimetry are given.
