Ionizing Radiation

Ionizing radiation is a well-established carcinogen. Sources of this exposure range from radioactive fallout or environmental contamination from nuclear weapons testing or accidents at nuclear power plants, weapons manufacturing and other facilities, medical exposure from both diagnostic and therapeutic procedures, and the natural environment such as cosmic radiation from the sun and radon emitted from rocks deep underground. DCEG researchers investigate the effect of radiation dose on individual cancer risk using modeling studies, and direct assessment through cohort studies of exposed populations.
