Thermoluminescence (TL) of pyrite (FeS 2 ) has been investigated to study the kinetics of single peak glow curves. The material used normally exhibits one large and four small peaks. However, a glow curve can be obtained with only the large single pe

The validity of thermoluminescence (TL) glow curve analysis by repeated initial rise (initial slope) measurements has been studied by computer simulation. Thermoluminescence described by first order, second order, general one trap (GOT), and interact

Optical absorption measurements have been made on unirradiated and irradiated samples of cerium oxide doped lead silicate particle detector glasses. The addition of CeO2 introduces one prominent and one weak absorption band near the ultraviolet trans

The thermoluminescence (TL) glow peaks obtained from materials exhibiting two or more glow peaks, e.g. NaCl, quartz and other minerals, often appear to be well described by the well-known first and second order TL kinetics. However, in many cases phy

Radiation damage, particularly Na metal colloid formation, has been studied in synthetic NaCl and natural rock salt using unique equipment for making optical absorption, luminescence and other measurements during irradiation with 1–3 MeV electrons.

The radiation induced absorption, i.e. coloring, has been determined for two lead silicate glasses used in Cherenkov counters. The measurements were made on Schott SF5 and Ohara PEMG4 glasses. Both the radiation induced absorption spectra and the col

KCl F-center coloring curves measured at room temperature on unstrained crystals contain one linear and three saturating exponential components. After deformation beyond 0.25 per cent, the coloring is markedly increased, and is described by a linear
