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...

Background: The goals of the present research were to investigate the rectal dose during four chosen techniques of cervical cancer radiotherapy and to examine how accurately the treatment planning represents dose measurements, and it’s practicality for routine use as well as, to determine the homogeneity of dose in tumor volume. Materials and Methods: The study was carried out using a Nepton 10...

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...

Background: Radioiodine therapy has proven to be an effective method in the treatment of patients with differentiated thyroid carcinoma after thyroidectomy. The scope of this study is to describe a method to obtain the dose of organs using medical internal radiation dosimetry (MIRD) method. At the end, the results of MIRD calculations were compared with thermoluminescent dosimeter (TLD...

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...

CyberKnife is one of multiple modalities for stereotactic radiosurgery (SRS). Due to the nature of CyberKnife and the characteristics of SRS, dose evaluation of the CyberKnife procedure is critical. A radiophotoluminescent glass dosimeter was used to verify the dose accuracy for the CyberKnife procedure and validate a viable dose verification system for CyberKnife treatment. A radiophotolumines...

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 ...
