We describe two example pilot efforts to help define new thermoluminescent dosimeter media. The first concerns ZnS:Mn nanophosphors, prepared by chemical precipitation using zinc and sodium sulfate, doped with manganese sulfate at concentrations varying from 1 to 3mol. The second concerns chemical vapor deposited diamond, produced as a thin film or as amorphous carbon on a single-crystal silico...

INTRODUCTION The thermoluminescent (TL) properties of various materials have been studied since a long time but many of these developments never reach the thermoluminescent dosimeter (TLD) users. α-Al2O3:C TL detectors were first developed and produced at Urals Polytechnical Institute ( UPI ) (1) in the form of a single crystal. These TLD ( model 2600 – 80 ) are now supplied by Victoreen to man...

Satisfactory discrimination between the neutron and gamma components in a mixed neutron-gamma field is one of most important objectives dosimetry. One common techniques for estimating dose fields two peak method. This method has been applied using dosimeters such as LiF:Mg,Ti, but present work, 6LiF:Mg,Cu,P dosimeter used, whose thermoluminescence sensitivity much higher than LiF:Mg,Ti dosimete...

Since the beginning of its use, radiation has already presented harm, justifying the necessity of controlled use. In order to monitor its effects and even avoid them, dosimetry has arisen. For the purpose of ensured all the necessary safety and monitor areas where there is radiation use, a lot of devices able to identify and quantify many types of radiation were developed. However, some these d...

Abstract The present article deals with potassium magnesium borate glass activated copper that was prepared by a melting quenching technique to study the feasibility of this as radiation dosimeter. glasses were characterized through X-ray diffraction and FTIR spectroscopy some optical physical parameters have been interpreted. thermoluminescence properties samples studied, results revealed dope...

background: thermoluminescence dosimetry is one of the dosimetry procedures used widely as routine and personal dosimeters. in order to extend this kind of dosimeters, dental tissue has been examined and was found promising as a tld dosimeter. materials and methods : in this study, 70 health teeth were collected. the only criterion, which was considered for selection of the teeth, was the healt...
