Today I will describe the dissemination efforts at the National Institute for Occupational Safety and Health (NIOSH). NIOSH is both a research institution and a public health institution. We conduct a wide range of programs-from etiologic and intervention research to dissemination of our materials. These activities are summarized in our vision: "Delivering on the nation's promise: safety and health at work for all people through research and prevention." NIOSH publishes more than 200 journal articles and documents each year. Most of these occur in peer-reviewed scientific journals. However, some are technical reports, educational documents, various kinds of health and hazard alerts, and policy documents. Our materials are directly disseminated through peer-reviewed journals, patents, research partnerships, and databases. NIOSH policy, technical, and educational documents are disseminated in paper and electronic versions. They are also mounted on the NIOSH Web site and are available for downloading. NIOSH has a number of databases that we share with the public through the NIOSH Web site and other sources. These include NIOSHTIC and the Registry of Toxic Effects of Chemical Substances (which is the largest toxicologic database in the world) and various surveillance databases that pertain to a wide range of topics such as traumatic fatalities, injuries, blood lead levels, and sentinel health events.
