Factors affecting the precision of TLD dose measurements using an automatic TLD reader
Physics in Medicine and Biology, 1995An increase in the variability of TLD dose measurements prompted a study of the precision of dose measurements with a Rialto automatic TLD reader. It was found that readings with the same chip measured using two different trays could differ by as much as 7%.

To improve the performance of mono-extruded TLD threads as a dosimetric thermoluminescent tool (French Patent 9903729), a new process was developed by co-extrusion methodology leading to threads of 600 microm diameter with a 50 microm homogeneous polypropylene sheath.

Thermoluminescent dosemeters (TLDs) provide a valuable means of measuring dose distributions in clinical practice. A problem arises, however, in handling, labelling and positioning the individual dosemeters, which must be kept as clean as possible at all times.

A Comparison of TLD and Film for Personnel Dosimetry
Health Physics, 1966Abstract The film badge is today the most widely used personnel monitoring device for want of a more reliable and accurate system. Recent evaluations of the performance of the available commercial film badge services report a wide variation in both the accuracy and consistency of the reported exposures.

Comparison of LiF (TLD-100 and TLD-100H) detectors for extremity monitoring
Radiation Measurements, 2008Abstract In this work the results aimed at assessing the performance of two types of LiF detectors, TLD-100 and TLD-100H, used in the context of extremity dosimetry are presented. Each detector variety was studied for reproducibility, batch homogeneity, residual dose, linearity and energy dependence using, when appropriate, the 90 Sr/ 90 Y radiation

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 ...

ANALYTICAL SIMULATION OF TLD AND ASSESSING THE EFFECTS OF TLD ON THE RESIDUAL DISPLACEMENT
Various control systems have been implemented to mitigate the effects of earthquakes on buildings, aiming to reduce the kinetic energy generated by dynamic activity caused by earthquakes and wind. Among these systems, Tuned Mass Dampers (TMD) and Tuned Liquid Dampers (TLD) serve as cost-effective and practical passive control mechanisms.Dağ, Birkan, Börekçi, Muzaffer

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.

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 ...
