RADAR is a framework for evaluating information created by Jane Mandalios of the American College of Greece in 2013. RADAR strives to be an information evaluation framework, not a be-all and end-all requirement. If an information source raises concern on your RADAR, there is probably a good reason, and there may be a problem with the information. RADAR can help you remember what questions to ask to determine if a source of information is good for your research. If you are still unsure at the end of your search, do not be afraid to contact the library and ask for a help.
