Abstract
The need to improve the scientific bases for recommendations and regulations to protect human health from ionizing radiation and associated hazards has resulted in the creation by the U.S. Department of Energy (DOE) of a training program for radiation scientists at the University of Pittsburgh. In addition, the DOE's Office of International Health Programs (IHP), together with other national and international agencies, supports international meetings focused on health effects of radiation exposures. The IHP also provides fellowships to scientists from other countries, making it possible for them to attend relevant meetings of the American Association for the Advancement of Science. These and other international collaborative efforts, in particular those focusing on research in conjunction with Russian scientists, are described.
