Study of Optically Stimulated Luminescence of LiF:Mg,Ti for beta and gamma dosimetry

• Study of Optically Stimulated Luminescence of LiF:Mg,Ti and microLiF:Mg,Ti.
• OSL response of TLD-100 dosimeters to beta and gamma radiation.
• Analysis of repeatability and lowest levels of detection of detectors LiF:Mg,Ti.

Modern advances in radiation medicine – radiodiagnosis, radiotherapy and interventional radiography – each present dosimetry challenges for the medical physicist that did not exist previously. In all of these areas a constant balance has to be made between the treatment necessary to destroy the tumor and the unnecessary exposure of healthy tissue. Innovative applications of OSL dosimetry are now appearing in each of these areas to help the medical physicist and oncologist design the most effective, and least deleterious, treatment for their patients. High sensitivity, precise delivery of light, fast readout times, simpler readers and easier automation are the main advantages of OSL in comparison with TLD.This work aimed to study the application of OSL technique using lithium fluoride dosimeters doped with magnesium and titanium (LiF:Mg,Ti) for application in beta and gamma dosimetry.
