‘Tracers’ are bullets that emit light at the backside so shooter can see trajectory of their flight. These light-emitting allow snipers to hit targets faster and more accurately. Conventional tracers all combustion type which use heat generated upon ignition. However, conventional tracer has a fire risk impact site due residual flame by-product contaminate inside gun lead firearm failure. To re...

a lithium borate thermoluminescence dosimeter with 0.3 wt% of manganese impurityconcentration was prepared for high dose levels in the range of 1-30 kgy for gamma irradiation applications.the tld reader was used for read out purposes from ambient temperature to about 400°c with a heating rate of 6°c/sec. the pre- and post- irradiation anneal temperature was 300°c for 1.5 and 1 hours respectivel...

an improved mixed order model is presented to describe the thermolumunescence (tl) glow peaks. in this model a fraction of charge carriers, which undergo nonradiative recombination following thermal excitation is taken into account. therefore, it is expected that the proposed model will produce more realistic kinetic parameters than that of mixed order model. the tl glow curves generated by the...

Abstract Nanocrystalline boehmite material was synthesized using the hydrothermal method. Different annealing temperatures have been used to transform into different alumina phases study effect of phase transitions on thermoluminescence properties alumina. XRD analysis carried out investigate crystal structure phases. The glow curves for showed structures; however, sensitivity almost constant a...

Sr2SiO4:%3Nd3+ was synthesized and its structural characterization made via XRD technique. The results indicated that had Pmma (62) space group (PDF: 00-039-1256) in the orthorhombic crystal system. Luminescence thermoluminescence (TL) properties of Sr2SiO4:%3Nd3 investigated detail. Computerized glow curve deconvolution methods used for to determine kinetic Sr2SiO4:%3Nd3+. TL showed Sr2SiO4:Nd...
