High intensity x-ray beam是什么
Web10 de abr. de 2024 · Radiochromic films have widely been used for quality assurance (QA) in radiation therapy and have many advantageous features such as self-developing visible coloration, wide dose range and easiness to handle. These features have a good potential for application to other fields associated with high-dose radiation exposure, e.g., … WebX-ray-induced radiation damage. We will illustrate in detail the impact of the exposure to high X-ray doses on the struc-ture, morphology and optical emission of individual NWs. In this study, two separate experiments have been carried out using the same beam conditions, i.e. photon flux, energy and beam size, where individual NWs are continuously
