about the department

Environmental and Radiological Health Sciences

The Department of Environmental and Radiological Health Sciences is home to one of the largest environmental health programs in the nation, and the only one that incorporates radiological health into its core curriculum. Students and researchers in environmental health investigate how natural and built environments affect human and animal health and seek solutions to minimize negative health consequences of environmental and workplace exposures. Radiological health has a long tradition at CSU focused on the biological effects of radiation, including laboratory studies of the damaging effects of radiation, and clinical uses of radiation in diagnostic imaging and cancer therapy.
