An Integrating Thermoluminescent Rn Daughter Personal Dosimeter
Health Physics, 1987An integrating Rn daughter dosimeter using conventional Dy-doped CaSO4 thermoluminescent (TL) material has been developed for use as a personal monitor. The dosimeter was found to have a linear response over the range 0.5 WL-h to 25 WL-h and to be insensitive to the state of equilibrium of the Rn daughters.

High dosage thermoluminescence diamond dosimeters
Journal of Superhard Materials, 2012Diamond thin films have been irradiated with high doses (up to 12.8 kGy) of 90Sr beta particles. The diamond thin films have been synthesized from commercial Tequila as a precursor using Pulsed Liquid Injection by the Chemical Vapor Deposition (PLICVD) technique reported recently.

Tritium production in LiF thermoluminescent dosimeters
The International Journal of Applied Radiation and Isotopes, 1980LiF thermoluminescent dosimeters (TLDs) are commonly employed in mixed neutron/γ-radiation environments utilising the high probability of the reaction 6Li(n,α)3H for thermal neutrons. Details of the theoretical and experimental determination of the amounts of tritium generated in the TLDs are given and conclusions drawn on the implications for Health ...

Sensitivity and stability of LiF thermoluminescence dosimeters
Medical Dosimetry, 1995Three different batches of LiF TLD-100 rods were subjected to investigation of their radiation sensitivity and the stability of the sensitivity after subsequent cycles of irradiation readouts. An old batch (circular rods from 1985), R85, showed an initial sensitivity of approximately 720 (nC/Gy).

Novel non-thermoluminescent CaSO4:Dy dosimeters
Applied Radiation and IsotopesThe non-thermoluminescence afterglow-based dosimetry performance of self-agglomerating pellet-shaped CaSO4:Dy phosphors synthesized through a low-cost, environmentally friendly method is first reported. Thermoluminescence (TL) and afterglow (AG) were analyzed in samples exposed to beta particle irradiation in the dose range from 0.06 to 8.0 Gy ...

A Lithium Fluoride Thermoluminescent Dosimeter
1965Report in the literature of the use of a thermoluminescent dosimeter using Lithium Fluoride have been most encouraging particularly in view of the nearness of the atomic number of the detecting material to that of tissue. The reported size of a satisfactory dosimeter too added considerably to its promise as a clinical instrument.

Electric heater for thermoluminescence dosimeters
Soviet Atomic Energy, 1987This article describes an electric heater, integrated with a thermistor and a control circuit, designed for heating a thermoluminescent dosemeter and regulating its temperature. Advantages over previous dosemeter heating systems are listed as are performance test results.

Phosphorescence Method of Reading Thermoluminescent Dosimeters
Review of Scientific Instruments, 1963It is shown that multiple readings of thermoluminescent dosimeters can be made by using the ``steady-state'' phosphorescence brightness at a temperature well below the glow peak temperature. Following such readings the devices can be read in the normal way, with appropriate calibration factors to correct for the partial exhaustion of the phosphor by ...
