BACKGROUND AND PURPOSE Since 1969 the International Atomic Energy Agency (IAEA), together with the World Health Organization (WHO), has performed postal TLD audits to verify the calibration of radiotherapy beams in developing countries. MATERIALS AND METHODS A number of changes have recently been implemented to improve the efficiency of the IAEA/WHO TLD programme. The IAEA has increased the n...

BACKGROUND Third location decompression (TLD) refers to the initial process, undertaken by military personnel at the end of an operational deployment, whereby adjustment from military operations commences. TLD has been shown to be useful for personnel in formed units (FU). AIMS To examine the subjective utility of TLD for personnel deployed as individual augmentees (IAs) by comparing their ex...

Tandem systems formed with different thermoluminescent dosemeters were evaluated in standard diagnostic radiation beams. The utilized materials are commercially available, and the aim of this study was to carry out a performance comparison. The results show that the energy dependence of the materials, except TLD-100, were very high. Therefore, there are several possibilities of pair combination...

The possible defect structure of peak 1 of LiF:Mg,Ti (TLD-100) was studied in the present work after different pre-irradiation heat treatments between 80◦C and 150◦C using the computer glow curve deconvolution (CGCD) method. It was shown that the defect structure of peak 1 is based on colloid centers, Ti-3O2 -mixed centers and U1-centers.

INTRODUCTION The Czech thermoluminescent dosimeters (TLD) quality assurance network was established in 1997. Its aim is to pursue a regular independent quality audit in Czech radiotherapy centres and to support state supervision. MATERIALS AND METHODS The audit is realised via mailed TL dosimetry. The TLD system consists of encapsulated LiF:Mg,Ti powder (type MT-N) read with Harshaw manual re...

In the downlink cloud radio access network (C-RAN), fronthaul compression has been developed to combat the performance bottleneck caused by the capacity-limited fronthaul links. Nevertheless, the state-of-arts focusing on fronthaul compression for spectral efficiency improvement become questionable for energy efficiency (EE) maximization, especially for meeting its requirements of large-scale i...
