Abstract

 Background: An effec ve polymer gel dosimeter can be fabricated by varying the composi on of its chemical components. Materials and Methods: The MAGAT gel dosimeter formula ons that used different composi ons of Methacrylic acid (MAA) and gela n were extensively inves gated in the present study according to the R2– dose response and R2– dose sensi vity. The irradia on of MAGAT gel was performed by 6-MV photon beam at a dose range 1 to 10 Gy and was imaged by 1. 5T Magne c Resonance Imaging (MRI). The dose response of MAGAT gel dosimeter was obtained from spin-spin relaxa on rate (R2) of MRI signal. Results: The MAGAT gel dosimeter composed of 5% gela n and 6% MAA gave the highest sensi vity (1. 1180 s-1Gy-1). Conclusion: Understanding the effects of the composi onal changes will help to clarify the mechanisms involved in the dose response of the MAGAT gel dosimeter.
