Online discussion forums, wikis, movies, podcasts, journal clubs, online communities, and interactive experiences that supplement medical education are now widely available to residents and practicing radiation oncologists. We identify, categories, and critically assess podcasts, smartphone applications, web-based multimedia, and educational websites for radiation oncologists in this review. OVID-MEDLINE, PubMed, and a mix of pertinent search phrases were used to conduct literature searches throughout a two-month period (April to May 2022). E-learning resources were examined on the websites of pertinent radiation oncology societies. To find digital materials for radiation oncology education, online searches were made using search engines like Google, app shops, and websites for podcast producers. To establish credibility, materials were evaluated by two independent reviewers using the authority, accuracy, objectivity, currency, depth, and appearance criteria per suggested formats for evaluating digital resources in medical literature. 425 citations were found in literature searches conducted using OVID-MEDLINE and PubMed. The ones that apply to radiation oncology give examples of resource development, curricular integrations, interactive modules, case studies, and learner experiences. The multilevel search found 47 free digital learning materials, some of which required membership or a price for full access, including online radiation oncology tutorials, podcasts, films, slide sets, applications, and other interactive tools. Residents in radiation oncology have access to a wide range of online learning resources, which are great for furthering their study. To help doctors who are becoming more dependent on digital resources, particularly in light of the COVID-19 pandemic, this evaluation offers the first thorough overview of the online education tools for radiation oncologists that are now available
