Phototransferred thermoluminescence for use in UVB dosimetry.
Results are reported of a study of phototransferred thermoluminescence (PTTL) as a potential method for ultraviolet (UV) radiation dosimetry using several different TL materials. The materials studied in depth include Al2O3:C, CaF2:Cu, MgO and MgO:Cu. The experimental features discussed in this paper include the PTTL response as a function of exposure time at 307 nm and the PTTL wavelength dependence over the range 250-450 nm, using a fixed photon flux at the sample. The study confirms the attractive properties of Al2O3:C as a UV dosimetry material, while CaF2:Cu is shown to have potential as a UVC dosemeter.
