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 ...

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.

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.

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 ...

The dose–response of Harshaw TLD-700H
Radiation Protection Dosimetry, 2006Harshaw TLD-700H (7LiF:Mg,Cu,P) was previously characterised for low- to high-dose ranges from 1 microGy to 20 Gy. This paper describes the studies and results of dose-response and linearity at much higher doses. TLD-700H is a near perfect dosimetric material with near tissue equivalence, flat energy response, and the ability to measure beta, gamma and

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 ...

PTTL and TLD-100 and TLD-700 after irradiation with Pu-Be neutrons
2007Phototransfered 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 ...

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.
