A TLD System for Environmental Monitoring
Radiation Protection Dosimetry, 1996A multi-element dosemeter system for environmental monitoring has been designed. It consists of three solid sintered CaSO 4 :Dy (or CaSO 4 :Tm) properly filtered, and of one low Z, MgB 4 O 7 :Dy,Na TL detectors. This TL dosemeter system is shown to meet all specified criteria and provides the accurate dosimetry required for environmental monitoring ...

Influence of the Mn-dopant on the TLD-system CaF2 : Dy(TLD-200)
Nuclear Instruments and Methods, 1980Abstract Systematic investigations (ESR, IR, electron excited optical emission, glow curve analysis) of the centers involved in the TL-process of commercially available CaF 2 : Dy (TLD-200) and crystals grown by a modified Bridgman-Stockbarger method doped with Dy and Mn are described and the results are discussed.

Self-shielding factors for TLD-600 and TLD-100 in an isotropic flux of thermal neutrons
Physics in Medicine & Biology, 1976Monte Carlo calculations have been carried out to determine the absorption probability (and consequently the self-shielding factor) for an isotropic flux of neutrons impinging on different sized cylindrical samples of TLD-100 and TLD-600.

TL and PTTL of TLD-100 and TLD-700 after irradiation with Pu-Be neutrons
Radiation Measurements, 2008Phototransfered thermoluminescence (PTTL) found its use in radiation dosimetry for dose reassessment. After the dose has first been evaluated by a common thermoluminescence (TL) measurement, the same dosimeter is subjected to the PTTL dose reassessment with the intention of obtaining a new estimation by a completely independent measurement procedure ...

Radiation Protection Dosimetry, 1996
High pre- and post-irradiation fading prevents the attainment of high accuracy in dosimetry measurements, especially in routine dosimetry when the exact duration and time of exposure are not known. An attempt was made at the Soreq Dosimetry Centre to reduce the fading following or preceding gamma radiation, by employing a high post-irradiation preheat ...

Environmental monitoring with TLD
Nuclear Instruments and Methods, 1972Abstract CaSO 4 :Dy has advantages for environmental TLD: It can easily be prepared, is ≈30 times as sensitive as LiF:Mg,Ti, and exhibits considerably less fading than previously used CaF 2 :Dy.

An improved TLD target tracking algorithm
2016 IEEE International Conference on Information and Automation (ICIA), 2016Target tracking has always been a hot research topic in the field of computer vision. Tracking-Learning-Detection (TLD) is a new algorithm for online learning tracking proposed by Zdenek Kalal. In the algorithm, the computation consuming of detection module is relatively large.

Comparison of some TLD dosimetry systems
The British Journal of Radiology, 1973The application of thermoluminescent dosimetry has become more and more common in clinical practice. Several dosimetry systems have been introduced on the market lately. Four of such TLD (thermoluminescent dosimetry) systems have been installed for some time in our hospital, so that a comparison could be made between them.

Extremity TLD High Dose Response
Radiation Protection Dosimetry, 2002The Extremity TLD service provided by the UK National Radiological Protection Board (NRPB) supplies dosemeters to 3200 wearers in various occupations, primarily in the industrial, research and medical sectors. The dosemeters and associated processing equipment were supplied by Bicron/NE Technology Ltd and the service in this form has been operating ...

Microprocessor Controlled Portable TLD System
Radiation Protection Dosimetry, 1996An up-to-date microprocessor controlled thermoluminescence dosemeter (TLD) system for environmental and space dose measurements has been developed. The earlier version of the portable TLD system, Pille, was successfully used on Soviet orbital stations as well as on the US Space Shuttle, and for environmental monitoring.
