This Dose Assessment Guidance (DAG) describes methods used to comply with the reporting requirements for individual receptor and collective dose for radionuclide air emissions under the U.S. Department of Energy, Office of Science, Pacific Northwest National Laboratory (PNNL) Environmental Monitoring Plan (EMP). The National Emission Standards for Hazardous Air Pollutants (40 CFR 61), Subpart H, is the greatest driver for the requirements. This DAG applies to public dose from radioactive material releases to the air from PNNL Richland Campus and Marine Sciences Laboratory (Sequim, Washington). The application of Richland Campus ambient external dose results is also briefly discussed. The methods used to perform the biota dose assessment reported in the Site Environmental Report are discussed.
This guidance is Attachment 3 to PNNL’s EMP (PNNL-20919) and addresses a discrete, vital subject area of the EMP that is subject to revision independent of the main text of the EMP document.
