Center for Radiological Research

The Columbia University Center for Radiological Research (CRR) was founded more than 75 years ago to better understand the human health risks associated with exposure to ionizing radiation exposure. It is the oldest and largest such research center in the world. The Center's efforts are focused on unraveling the biological and molecular mechanisms underlying radiation effects in cells, tissues, organ systems and living organisms and how radiation exposure affects human health. Its primary mission is to provide an unbiased, comprehensive and independent source of scientific information about radiation risks to governmental agencies, elected officials, non-profit institutions and private entities to enable them to make sound, evidence based policy decisions. The CRR also provides basic science training to the next generation of radiobiologists, medical and health physicists and clinical radiologists. The Center's multidisciplinary staff encompasses professionals from diverse fields including molecular biology, cell biology, radiation physics, computational physics, engineering, radiation oncology and public health.
