It utilizes quantitative analysis and statistics to describe patterns of publications within a given topic, field, institute, or country. One common way of conducting bibliometric research is to use the Science Citation Index (SCI) databases to trace documents. The objective of the study was to perform a bibliometric analysis of all literature of risk assessment applications in regulatory toxicology in the Science Citation Index (SCI). Analyzed parameters included authorship, patterns of international collaboration, journal, language, document type, and author’s address. Methods Documents used in this study were based on the databases of the SCI which was accessed from the ISI Web of Science, Philadelphia, PA, USA. A keyword search, using the following terms, was performed to identify risk assessment applications in regulatory toxicology studies published between 1991 and 2004: risk assessment, risk assessments, safety evaluation, health assessment, health assessments, health risk assessment, health risk assessments, regulatory toxicology, regulation, regulations, guideline, and guidelines.

Major characteristics of the production of hyperthermia and cancer researchResults Ten document types were found in the total of 1,622 documents. English was the dominant language with 28% of the articles being authored by single author.
