Deconvoluted glow curves following ⁹⁰Sr/⁹⁰Y irradiation: naturally cooled material (right); slow-cooled material (left).

Deconvoluted glow curve following 1.5 keV electron irradiation in a slow-cooled sample.

Intensity ratios of 5a/5 as a function of ionisation density/LET for different charged particle species.

Deconvoluted glow curve following 7.5 MeV alpha particle irradiation in a slow-cooled sample.

Deconvoluted glow curve following 2.0 MeV alpha particle irradiation in a slow-cooled sample.

Deconvoluted glow curve of LiF:Mg,Ti (TLD-100) into component glow peaks following irradiation by ⁹⁰Sr/⁹⁰Y beta (top) and alpha particles (bottom) in ‘naturally cooled’ samples. Note the enhanced intensity of peak 5a following the alpha particle irradiation.

Schematic representation of the molecular TC/LC complex giving rise to peak 4 and composite peak 5. Following irradiation, the complex can capture an e-h (giving rise to peak 5a)—an electron-only (peak 5), a hole-only (peak 4) or be un-occupied. The linear dose response is due to e-h recombination in the e-h-occupied complex. Reproduced from Horowitz and Olko ⁽¹⁾.

Comparison of glow curves following 6 MeV photon irradiation in ‘naturally cooled’ and ‘slow-cooled’ samples. Note the shift of T_max to lower temperatures in the slow-cooled samples and the disappearance of the shoulder arising from peak 4. This is attributed to an increased intensity of peak 5a in the slow-cooled samples.
