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. <br><br>The Master of Science in radiological health, health physics specialization focuses on gaining an in-depth understanding of the risks and benefits associated with radiation in order to protect public health and the environment. Students also have the opportunity to choose a medical health physics track, which prepares students for health physics opportunities in a clinical setting, such as a hospital Radiation Safety Officer, and opens the door to a medical physics residency or entry level medical physics position in a radiotherapy clinic or radiology department.​
