PNNL

Dr. Colby Mangini is a certified health physicist at Pacific Northwest National Laboratory (PNNL). He has over 15 years of experience in health physics, with a background in applied and computational health physics, internal dosimetry, environmental assessment, and regulatory compliance. At PNNL, he supports nuclear incident response consequence management, radiological protection software development, and environmental assessments.

Dr. Mangini’s early career included health physics roles in the U.S. Naval Reactors Program, including 4 years as a commissioned officer in the U.S. Navy. His work has focused on training and development and advanced dosimetric techniques. Dr. Mangini’s work directly preceding PNNL built his foundation for environmental fate and transport modeling and dose reconstruction, which are skills he has applied to operating nuclear power plants, low-level waste storage facilities, and radiological release events such as Fukushima and the Woolsey Fire of 2018.
