A Preliminary Study of Light-Weighted and Flexible Bismuth Nanoparticle-Based Polymer Matrix for Efficient Radiation Shielding

Authors: Ming Su, Yuenan Nancy Wang

Affiliation: Northeastern University, Hartford Healthcare

Abstract Preview: Purpose: High Z elements such as lead are often used to protect critical structures in clinical radiotherapy. Nanoparticles have different properties than bulk materials. We proposed a polymer matrix ...

Feasibility of a Normoxic N-Vinylpyrrolidone-Based Polymer Gel (VIPET) Dosimeter for Three-Dimensional Proton Beam Measurements

Authors: Yoshihiko Hoshino, Kenji Hotta, Taeko Matsuura, Ai Nakaoka, Hidenobu Tachibana

Affiliation: Hokkaido University, Department of Radiology, Gunma University Hospital, Radiation Safety and Quality Assurance Division, National Cancer Center Hospital East

Abstract Preview: Purpose: Gel dosimeters enable three-dimensional dose measurements, but no reports have evaluated the fundamental performance of VIPER-type gel dosimeters in proton beam measurements. Therefore, we ev...
