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.
