Thermoluminescence dosimeters (TLD) are widely used to verify absorbed doses delivered from radiation therapy beams. Specifically, they are used by the Radiological Physics Center for mailed dosimetry for verification of therapy machine output. The effects of the random experimental uncertainties of various factors on dose calculations from TLD signals are examined, including: fading, dose resp...

Satisfactory discrimination between the neutron and gamma components in a mixed neutron-gamma field is one of most important objectives dosimetry. One common techniques for estimating dose fields two peak method. This method has been applied using dosimeters such as LiF:Mg,Ti, but present work, 6LiF:Mg,Cu,P dosimeter used, whose thermoluminescence sensitivity much higher than LiF:Mg,Ti dosimete...

Thermoluminescence (TL) and optically stimulated luminescence (OSL) techniques are known as a research tools for the study of phosphor materials and for their applications in radiation dosimetry in particular [1]. Although TL technique is known since several decades, OSL is relatively newer technique. The TL or OSL emission from an irradiated sample arises upon stimulation with heat or light re...

In the field of thermoluminescence dosimetry the daily analysis of multi-peak glow curves includes computerized curve-fitting methods, the so-called deconvolutions. These are in need of restricting the kinetic parameters E and s in order to obtain physically relevant results. There have been suggested various methods for the determination of these kinetic parameters based on a theory treating s...

Electron paramagnetic resonance, thermoluminescence, and optically stimulated luminescence, with biological tissues inert materials are well established physical methods for retrospective dosimetry in acute accidental exposures. The objective of this article is to provide a view the questions still open, current challenges needed solutions. As research on emergency response encountering increas...

background: accelerated partial breast irradiation via interstitial balloon brachytherapy is a fast and effective treatment method for certain early stage breast cancers however skin, chest wall and lung doses are correlated with toxicity in patients treated with breast brachytherapy. objective: to investigate the percentage of the dose received by critical organ (skin), thermoluminescence dete...

The pre-dose technique in thermoluminescence (TL) is used for dating archaeological ceramics and for accident dosimetry. During routine applications of this technique, the sensitisation of the quartz samples is measured as a function of the annealing temperature, yielding the so-called thermal activation characteristic (TAC). The measurement of multiple TACs and the study of the effect of UV-ra...

The phosphate glass samples doped with Tb2O3 oxide (general formula: P2O5-Al2O3-Na2O-Tb2O3) were synthesized and studied for usage in high-dose radiation dosimetry (for example, high-activity nuclear waste disposals). influence of terbium concentration on thermoluminescent (TL) signals was analyzed. TL properties glasses investigated using various experimental techniques such as direct measurem...
