Joel Cehn

Document Analyst

Joel Cehn is a Q-cleared document analyst for the Los Alamos Historical Document Retrieval and Assessment Project.

  • Certified Health Physicist, American Board of Health Physics, 1997
  • M.S., Nuclear Engineering, North Carolina State University, 1971
  • B.S., Physics, Worcester Polytechnic Institute, 1969

Joel Cehn directed an investigation into radioactive airborne effluents from particle accelerator facilities. Total U.S. releases were quantified through existing data, calculations, and confirmatory measurements. He also directed a radiological assessment for the U.S. EPA of airborne effluents from various facilities that handle radioactive materials. The assessment included measurement of stack effluents to confirm published data. Joel participated on an U.S. EPA inspection team that traveled to various DOE facilities including Mound Laboratories, Lawrence Berkeley Labs, and Los Alamos National Laboratory to evaluate compliance with the National Emission Standards for Hazardous Air Pollutants (NESHAP). He also conducted a safety review of the Plutonium Finishing Plant at the U.S. DOE Hanford Site. As a member of an EPA inspection team, he reviewed radiation safety and criticality safety efforts at the plant, following a plant upgrade. The inspection team was tasked with examining plant safety prior to allowing re-start. Joel's work in the nuclear power industry includes a survey of radio-iodine releases from a nuclear power plant and recommendations for reducing releases, and evaluation of the environmental, radiological impacts from operation of the Pilgrim Nuclear Power Station for compliance with federal regulations.
