This paper describes a new radiation shielding material, amethyst ore. We have determined
the elemental composition of amethyst using WDXRF spectroscopy technique. To see the …

In the present study, certain natural silicate minerals such as aquamarine (AB), morganite
(PB), goshenite (WB), white jadeite (JW), green jadeite (JG), pink tourmaline (PT) and two …

Rose quartz is an interesting mineral with numerous impurities that have been studied by
scanning electron microscopy (SEM), X-ray fluorescence (XRF), X-ray diffraction (XRD) …

Extensive Thermoluminescence (TL) glow curve analysis of natural (S1) and heat-treated
(S4) Pakistani Onyx marble is reported exploring an alternative natural radiation dosimeter …

In preparing of thermoluminescent dosimeters (TLD) it is common to use as agglutinator the
polytetrafluoroethylene (PTFE), called Teflon®. In this paper the physical, morphological and …

Abstract Topaz (Al 2 F 1· 44 (OH) 0· 56 SiO 4)/corundum (Al 2 O 3) composites were
prepared by a facile and novel reversible process from the sintering of synthetic topaz and …

This study shows that there are some ionic crystals which after irradiation with high gamma
dose D m and subsequent irradiation with low doses ranging up to 500 Gy present a …

A Monte Carlo study of the energy response of an aluminium oxide (Al2O3) detector in
kilovoltage and megavoltage photon beams relative to 60Co gamma rays has been …

A study of the thermoluminescent (TL) characteristics of white, black and stripped onyx
samples is reported in this work. Onyx is a variety of chalcedony, a form of quartz. The onyx …

The possibility of using different materials for thermoluminescent dosimetry agglutinating
their powder with Teflon®(a polymer) has been studied in recent years. In this paper the …
