This study characterizes the literature of the radiation therapy profession, identifies the journals most frequently cited by authors writing in this discipline, and determines the level of coverage of these journals by major bibliographic indexes.
Cited references from three discipline-specific source journals were analyzed according to the Mapping the Literature of Allied Health Project Protocol of the Nursing and Allied Health Resources Section of the Medical Library Association. Bradford's Law of Scattering was applied to all journal references to identify the most frequently cited journal titles.
Journal references constituted 77.8% of the total, with books, government documents, Internet sites, and miscellaneous sources making up the remainder. Although a total of 908 journal titles were cited overall, approximately one-third of the journal citations came from just 11 journals. MEDLINE and Scopus provided the most comprehensive indexing of the journal titles in Zones 1 and 2. The source journals were indexed only by CINAHL and Scopus.
The knowledgebase of radiation therapy draws heavily from the fields of oncology, radiology, medical physics, and nursing. Discipline-specific publications are not currently well covered by major indexing services, and those wishing to conduct comprehensive literature searches should search multiple resources.
本研究描述了放射治疗专业的文献，确定了该学科作者最常引用的期刊，并确定了主要书目索引对这些期刊的覆盖程度。
根据医学图书馆协会护理和相关健康资源分部的映射相关健康文献项目协议，对三个专业来源期刊的被引参考文献进行了分析。布拉德福的分散定律被应用于所有期刊参考文献，以确定最常被引用的期刊标题。
期刊参考文献占总数的 77.8%，书籍、政府文件、互联网网站和其他来源占其余部分。尽管总共引用了 908 种期刊标题，但大约三分之一的期刊引用来自仅 11 种期刊。MEDLINE 和 Scopus 对第 1 区和第 2 区的期刊标题提供了最全面的索引。来源期刊仅被 CINAHL 和 Scopus 索引。
放射治疗的知识库主要来源于肿瘤学、放射学、医学物理学和护理学领域。专业出版物目前没有被主要索引服务很好地涵盖，那些希望进行全面文献检索的人应该搜索多个资源。
