Synthesis of MgO Nanoparticles Containing Different Impurities and Evaluating Its Dosimeter Properties
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 5
Abstract
Today Ionizing Radiation has Widespread Applications In Different Scientific And Practical Areas Such As In Medical And Nuclear Centers As Well As Research Laboratories. Thermoluminescence dosimetry Is A WellKnown Method For Precise Determining The Absorbed Dose. Dosimetry and Dating Are Among The Most Important Applications Of Thermoluminescent Materials. The Aim Of This Research Is To Synthesize Mgo Nanoparticles Containing Different Impurities As Well As Evaluating Its Dosimeter Properties. In This Research, Nanoparticles Of Magnesium Oxide Containing Lithium And Lithium-Aluminum Impurities Were Synthesized. This Technique Is A New Method For Optimizing The Thermoluminescent Properties Of Materials And Expanding Their Dosimetric Applications. Using X-Ray Diffraction As Well As WilliamsonHall Plot, The Formed Phases And The Size Of Synthesized Nanoparticles Were Calculated. In Continue, Thermoluminescent Properties Of The Synthesized Nanoparticles And The Effect Of Impurities On Sensitivity of Thermoluminescence Nanoparticles Were Evaluated. The Results Showed That Adding Aluminium Can Significantly Increase The Intensity Of The Thermoluminescence Of Magnesium Oxide Containing Lithium Impurity. Thus Magnesium Oxide With A Little Amount Of Aluminium And Lithium Is Appropriate For Personal Dosimetric Goals As It Has High Sensitivity To Gamma Ray.
