Abstract:

Introduction According to the International Commission on Radiological Protection publication numbers 60 and 21, the environmental control standards should ensure human and other species protection to a desirable degree. Since application of radiographic procedures in Veterinary Medicine has increased significantly, in this study, we aimed to evaluate the entrance skin dose to the animals (e.g., dogs, cats, horses, and birds) undergoing diagnostic radiology. Materials and Methods The entrance skin dose to the animals in different radiology procedures were estimated through a) indirect estimation using the output of X-ray tubes and b) direct measurement using LiF:Mg, Ti  (TLD-100)  thermoluminescence dosimeter. Regression analysis was performed for comparison of the two methods. The animals included in this study were cats, dogs, small birds, horses, parrots, and chough. Results The dose received by the animals varied from 20 mGy to 1189.2 mGy, depending on the animal thickness, focal spot to surface distance, imaging technique, and animal type. Conclusion Optimized procedures are suggested for obtaining high-quality images, with a reasonably low dose imposed to the animals.

Investigation of LiF, Mg and Ti (TLD-100) Reproducibility

LiF, Mg and Ti cubical TLD chips (known as TLD-100) are widely used for dosimetry purposes. The repeatability of TL dosimetry is investigated by exposing them to doses of (81, 162 and 40.5 mGy) with 662keV photons of Cs-137. A group of 40 cubical TLD chips was randomly selected from a batch and the values of Element Correction Coefficient (ECC) were obtained 4 times by irradiating them to doses...

Localized transitions in the thermoluminescence of LiF : Mg,Ti: potential for nanoscale dosimetry

We describe the effect of nanoscale spatially coupled trapping centre (TC)–luminescent centre (LC) pairs on the thermoluminescence (TL) properties of LiF : Mg,Ti. It is shown that glow peak 5a (a low-temperature satellite of the major glow peak 5) arises from localized electron–hole (e–h) recombination in a TC–LC pair believed to be based on Mg–Livac trimers (the TCs) coupled to Ti(OH)n molecul...

quantitative evaluation of lif: mg, ti (tld-100) long-term sensitivity stability

background : sensitivity is an important dosimetric issue particularly in personal dosimetry where the range of doses is often very low to medium. in-service aging is assumed to be of negligible effect on the response of thermoluminescent dosimeters (tld), consequently, some service providers may mix fresh tlds to in-use ones and simply normalize the readings of tlds through batch calibration. ...
