Pion dosimetry with thermoluminescent materials

Physics in Medicine & Biology, 1980
Various thermoluminescent materials (6LiF, 7LiF, Li2B4O7:Mn, CaSO4:Dy, CaF2:Mn, CaF2-Dy, CaF2:Tm) were irradiated with pi- mesons throughout the depth dose distribution of a beam with central momentum of 176 MeV/c. Doses from 0.05 to 2 Gy were used and linearity and reproducibility were investigated.

Thermoluminescence Personnel Dosimetry at Hanford

American Industrial Hygiene Association Journal, 1971
In mid-1967, a flexible rubber finger ring utilizing a lozenge-shaped wafer of 7LiF in a Teflon matrix was introduced for routine hand dosimetry at Hanford. The thermoluminescence ring dosimeter provided a significant improvement over previously used film dosimeters, having a useful range of 0.02, to 105 R with a standard deviation of ±10%, minimal ...

Investigation on various types of silica fibre as thermoluminescent sensors for ultra-high dose radiation dosimetry

Sensors and Actuators A: Physical, 2018
With high-dose applications lacking the benefit of an economic yet versatile dosimeter that provides for a wide dynamic dose range, ongoing research is seeking to introduce suitable thermoluminescent (TL) material for such needs.

Instrumentation in Thermoluminescence Dosimetry

Radiation Protection Dosimetry, 1986
Abstract In the performance of a thermoluminescence dosimetry (TLD) system the equipment plays an important role. Crucial parameters of instrumentation in TLD are discussed in some detail. A review is given of equipment available on the market today - with some emphasis on automation - which is partly based on information from ...

Lithium Fluoride Thermoluminescence Dosimetry

Radiology, 1966
MANY MATERIALS in which irradiation causes excitation of electrons into energy states, which are stable at room temperature, have been found useful for thermoluminescence dosimetry. On subsequent heating of such a material, the de-excitation of the electrons results in the emission of light, and the light intensity may be plotted as a function of time ...

Lithium Fluoride Thermoluminescence Dosimetry

Physics in Medicine and Biology, 1964
Commercially available lithium fluoride thermoluminescent powder has been studied with a specially built readout device. Glow curves were recorded against temperature, and the area under them was integrated. A dispenser to deliver 30 mg batches of powder with a precision of 1% was built.

A Preliminary Study of Thermoluminescent Dosimetry

Radiology, 1962
A miniature solid state dosimeter based on the phenomenon of thermoluminescence (1) is presently being investigated in our laboratory for introduction into an in vivo dosimetry system, previously described by the authors (1, 3, 4). The radiation-sensitive element is a manganese-activated calcium fluoride phosphor.

Scintillation and thermoluminescent properties of Dy-doped calcium borate chloride

, 2021
Calcium borate chlorides (Ca2BO3Cl) with different concentrations of Dy3+ were fabricated by the conventional solid-state reaction with an aim to develop themoluminescent materials for radiation dosimetry, and their scintillation and thermally-stimulated

Milliroentgen Dosimetry with Thermoluminescence

Journal of the Optical Society of America, 1957
The primary purpose of this letter is to point out that thermoluminescence can be used for the measurement of extremely small radiation exposures in the range of ionization chambers and film badges.
