Use of light source for testing thermoluminescent dosimeter readers.
It is a common practice to check the performance of a TLD reader by inserting a light source composed of a phosphor mixed with a radioactive material, e.g., 14C . The response to the light source is used as a measure of a) the calibration or long-term stability of the reader and b) the ability of the reader to reproduce a constant signal. Usually the laboratory which measures a wide range of do...
متن کاملA search for novel thermoluminescent radiation dosimeter media.
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...
متن کاملSintered Al2O3 based Materials for Radiotherapy Thermoluminescent Dosimeter Applications
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...
متن کاملRadiation Monitoring Experiment Using Thermoluminescent Dosimeter for the Tr 19 Cyclotron Area in Nuclear Research Institute
The core of Radiopharmaceuticals Research Centre, CCR, is represented by a TR19 cyclotron (Advanced Cyclotron Systems Inc.), a versatile and fully automated and computer controlled machine. This cyclotron accelerates negative ions (H), on a vertically arranged plane, up to 19 MeV energy, and is provided with two external beam lines and dual extraction capabilities. The main use is for the produ...
متن کاملThermoluminescent Detectors for Neutron Dosimetry at High Altitudes
At high altitudes in the Earth’s atmosphere cosmic-ray induced neutrons become the dominant contributors to the biologically relevant dose equivalent. Depending on the geomagnetic latitude and the solar activity cycle, neutron dose onboard aircraft amounts to about 50 to 70 % of the overall dose equivalent. Neutron detection in complexly mixed radiation environments by means of active, i.e. pow...
