The Ph.D. in Radiological Health Sciences focuses on the study of radiation and its effects on humans, society, and the environment. Areas of emphasis include cancer research and the role of ionizing radiation in inducing, diagnosing, and treating cancer, radiation biology, health physics, radioecology and radiochemistry. The core curriculum provides a comprehensive background in the radiation and radiological sciences, enhanced by elective offerings in the department. The program is designed to support the development of students into independent scientists and to prepare them for careers in industry, government, and academia.
