Since all of the commercially-available readers are manually operated, measurements with thermoluminescent dosemeters (TLD) are time-consuming and require the undivided attention of the operator for an average of a minimum of one minute per reading. Thus when TLD's are to be used on a large scale, some form of automation is indicated.

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.

Nuclear Instruments and Methods in Physics Research, 1981
Abstract A thermoluminescent dosimeter (TLD) analyzer system utilizing photon counting techniques for signal registration was designed and evaluated for its low-dose measurement capabilities. A procedure is described whereby the photomultiplier tube applied voltage and the pulse-height discriminator level were optimized using signal-to-noise ratio ...

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.

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%.

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.

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 ...

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
