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...

The aim of this study was to evaluate radiation dose in patients undergoing three-dimensional rotation angiography (3DRA) and cone-beam computed tomography (CBCT) using a flat panel detector (FPD). Radiation doses were measured for angiography equipment using small silicon-photodiode dosimeters that were implanted in various positions in tissues and organs within an anthropomorphic phantom of a...

SIRADs (self-indicating instant radiation alert dosimeters) are designed to measure accident radiation doses. As the energy of radiation is usually unknown in such situations, a detector with a weak energy dependence of its response to dose would be ideal. We have studied the energy dependence of the dose response of SIRADs in the range from 50kVp to 10MV, which corresponds to photon equivalent...

Fricke-gel layer dosimeters (FGLD) and Fricke gel dosimetric catheters (FGDC) have been designed and tested with the aim of enquiring their suitability for HDR Ir brachytherapy source control and for in-vivo dose verification during treatment. Anisotropy function measurements have been carried out with FGLDs in which a thin plastic tube has been placed in for the Ir source insertion. FGDCs are ...

Young children and the developing fetus may be more susceptible to effects of environmental toxicants than adults due to differential exposure patterns and developmental immaturities. Biologic markers offer the potential of quantitative dosimeters of biologic dose and/or indices of biologic effect associated with fetal/childhood exposures. They can facilitate evaluation of interindividual varia...

The use of diamonds detectors in radiotherapy and its potential advantages over silicon diodes and ionisation chambers is reviewed. Preliminary results on the performance of CVD diamond detectors in an X-ray beam will be presented. While the devices are sufficiently sensitive, applications as dosimeters are at present limited by time dependent effects. Prospects for further work are described. ...
