Multivariate analysis of TLD orientation effects
Medical Physics, 1980The effect of orientation on extruded thermoluminescent dosimeters has been investigated. TLD's placed on the surface and within a phantom were exposed separately to five diagnostic beam qualities and to 60Co γ rays. The resulting data were subjected to analysis of variance and examined for significant correlations.

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.

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.

Commercial optical fibre as TLD material
Radiation Protection Dosimetry, 2006This work presents a study of commercial SiO2 optical fibre thermoluminescence (TL) properties as part of the efforts within the Dosimetric Application Project at the Physics Institute of the University of Mexico to develop new radiation detection materials and technologies.

Measurements of the Equivalent Dose in Aircraft with TLDs
Radiation Protection Dosimetry, 1999For measurements of the equivalent dose of the mixed radiation fields in aircraft many different measuring devices are usually necessary for consideration of the different components of the radiation field. The possibility is discussed of using thermoluminescence dosemeters (TLDS) for determination of absorbed dose and average LET of this complex ...

PITL and PTTL characteristics of TLD-100 and TLD-700 TL detectors
2006The phenomenon of thermoluminescence when excited by light (photostimulated thermoluminescence) has two aspects, photoinduced thermoluminescence (PITL) and phototransfered thermoluminescence (PTTL). PTTL refers to thermoluminescence (TL) induced by light as a result of photo transfer of charge carriers from one or more traps to other traps.

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 ...

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.

A Robotic Manipulator for Handling TLD Badges
Health Physics, 2008A prototype system for automatic handling of Harshaw/Bicron (now ThermoFisher Scientific) thermoluminescent dosimetry (TLD) badges, which is based on a robotic arm, was designed and built. The robot performs the loading and unloading of the TLD cards in the badges and transports them between the loading/unloading station and magazine stations.

Developmental roles of the BMP1/TLD metalloproteinases
Birth Defects Research Part C: Embryo Today: Reviews, 2006The astacin family (M12A) of the metzincin subclan MA(M) of metalloproteinases has been detected in developing and mature individuals of species that range from hydra to humans. Functions of this family of metalloproteinase vary from digestive degradation of polypeptides, to biosynthetic processing of extracellular proteins, to activation of growth ...
