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...

BACKGROUND An acute bout of eccentric contractions (ECC) cause muscle fiber damage, inflammation, impaired muscle function (MF) and muscle soreness (MS). Individually, protein (PRO) and antioxidant (AO) supplementation may improve some aspects of recovery from ECC, though have yet to be combined. We sought to determine if combined PRO and AO supplementation (PRO + AO) improves MS and MF followi...

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...

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...

PURPOSE To present experimental dosimetry results for the new IsoSeed I25.S17plus (125)I brachytherapy source, in fulfillment of the American Association of Physicists in Medicine recommendation for, at least one, experimental dosimetry characterization of new low-energy seeds before their clinical implementation. METHODS AND MATERIALS A batch of 100 LiF thermoluminescent dosimeter (TLD)-100 ...

Thymineless death (TLD) in bacteria has been a focus of research for decades. Nevertheless, the advances in the last 5 years, with Escherichia coli as the model organism, have been outstanding. Independent research groups have presented compelling results that establish that the initiation of chromosome replication under thymine starvation is a key element in the scenario of TLD. Here we review...

OBJECTIVE Third Location Decompression (TLD) is an activity undertaken by UK Armed Forces (UK AF) personnel at the end of an operational deployment which aims to smooth the transition between operations and returning home. We assessed whether TLD impacted upon both mental health and postdeployment readjustment. METHOD Data collected during a large cohort study was examined to identify personn...

background : sensitivity is an important dosimetric issue particularly in personal dosimetry where the range of doses is often very low to medium. in-service aging is assumed to be of negligible effect on the response of thermoluminescent dosimeters (tld), consequently, some service providers may mix fresh tlds to in-use ones and simply normalize the readings of tlds through batch calibration. ...

Since, choline chloride caking causes serious operating difficulties and customer complaints, two experiments were conducted to optimize in vitro production of a novel encapsulated choline chloride (ECC) with minimum hygroscopic property and optimize delivery in gastrointestinal tract (GIT). The in vivo verification test of ECC was used to compare it with the commercial choline chloride (CC) in...
