This list of radiation therapy resources is provided as a courtesy; we do not endorse materials not produced by the ASRT. The resources will assist R.T.s in sampling the pool of references and study materials that pertain to radiation therapy and should be viewed as a snapshot of available materials. Omission of any one title is not intentional. Because the creation of literature and media related to the field is dynamic, R.T.s are encouraged to search additional sources for recent updates, revisions and additions to this collection of titles. Some of these materials are out of print but are still relevant review sources.
