Calculation of Correction Factors for Dosimeters Thermoluminescent of Lithium Fluoride (LiF-100) for Use in 6MV Photon Beams

Since the beginning of its use, radiation has already presented harm, justifying the necessity of controlled use. In order to monitor its effects and even avoid them, dosimetry has arisen. For the purpose of ensured all the necessary safety and monitor areas where there is radiation use, a lot of devices able to identify and quantify many types of radiation were developed. However, some these dosimeters are more widely used today like ionizing chamber, chemical dosimeters, photographic dosimeters and thermoluminescent dosimeters (TLD). When a group of TLD is obtained with a quantity n of dosimeters, there is a variation of answer of these dosimeters when they are subjected to the same irradiations conditions, from this comes the importance of individual calibration of these, to select the dosimeters with close answers, reducing the uncertainties of the measures. Therefore, this work presents the calculation of correction factors for the TLD of lithium fluoride (LiF-100) and shows how this factors can improve the TLD’s readings.
