PNNL

Jonathan Napier is an environmental health physicist at Pacific Northwest National Laboratory (PNNL). He is an expert in environmental impacts to human health, waste, spent nuclear fuel, transportation, and decommissioning, supporting the U.S. Nuclear Regulatory Commission, Department of Energy, Department of Defense, and Department of Homeland Security. Prior to his work at PNNL, he was a health physicist for the Washington State Department of Health. While at the Washington State Department of Health, Napier authored radioactive materials licenses and performed license compliance inspections for medical, laboratory, and industrial uses of radioactive materials in the state. Napier started his career as a technical expert at Lawrence Livermore National Laboratory, where he provided support to procedural updates and to the Radiation Calibration Laboratory. He later transitioned to an Occupational Health Physics position supporting the National Ignition Facility. In this position, he conducted radiological impact assessments for new and continuing projects and implemented radiological protection requirements. Napier’s collective work experience allows him to assess radiological protection topics from multiple viewpoints.
