Plasmid DNA is useful for investigating the DNA damaging effects of ionizing radiation. In this study, we have explored the feasibility of plasmid DNA-based detectors to assess the DNA damaging effectiveness of two radiotherapy X-ray beam qualities a

This dissertation examines the extent to which radiobiological variations occur in photon radiotherapy, and then presents a novel methodology and detector prototype to measure this variation. In the first section, I examine the change in maximum RBE

PURPOSE Through the addition of high-Z dopants, the sensitivity of plastic scintillators to low-energy radiation can be increased. This study quantifies this change in sensitivity as a function of dopant concentration. METHODS Measurements were condu
