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...

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 order to solve the shortcomings of traditional TLDs (tuned liquid dampers), such as their narrow frequency bands and occupation large amounts space, based on deep-water theory, a new type TLD incorporating Karmen vortex street theory is proposed named KV-TLD. A shaking table experimental test conducted fully analyze its vibration damping characteristics effectiveness in terms control confirm...

The Drosophila tolloid (tld) and tolloid related (tlr) gene products belong to a family of developmentally important proteases that includes Bone Morphogenetic Protein 1 (Bmp1). Tld is required early in Drosophila development for proper patterning of dorsal embryonic structures, whereas Tlr is required later during larval and pupal stages of development. The major function of Tld is to augment ...

Radiation dosimetry is fundamental in Medical Physics, involving patients and phantom dosimetry. In both cases thennoluminescence dosimetry (TLD) is the most appropriate technique for measuring the absorbed dose. In this paper thennoluminescence phenomenon as well as the use of TLD in radiodiagnosis and radiotherapy for in vivo or in phantom measurements is discussed. Some results of measuremen...

Preliminary TLD results from the DOSMAP experiment on ISS G. Reitz, S. Deme, I. Apathy 1 German Aerospace Center (DLR), Cologne, Germany 2 KFKI Atomic Energy Research Institute, Budapest, Hungary Abstract: The Dosimetric Mapping (DOSMAP) experiment, operated by Expedition Two onboard the ISS attempted to record and map radiation inside Space Station within a four month period. One of the severa...

BACKGROUND The accurate results of the individual doses in personal dosimety which are reported by the service providers in personal dosimetry are very important. There are national / international criteria for acceptable dosimetry system performance. Objective : In this research, the sources of uncertainties are identified, measured and calculated in a personal dosimetry system by TLD. METHO...
