40 CFR Part 61, Appendix D to Part 61 - Methods for Estimating Radionuclide Emissions
|Controls||Types of radionuclides controlled||Adjustment factor to emissions||Comments and conditions|
|HEPA filters||Particulates||0.01||Not applicable to gaseous radionuclides; periodic testing is prudent to ensure high removal efficiency.|
|Fabric filter||Particulates||0.1||Monitoring would be prudent to guard against tears in filter.|
|Sintered metal||Particulates||1||Insufficient data to make recommendation.|
|Activated carbon filters||Iodine gas||0.1||Efficiency is time dependent; monitoring is necessary to ensure effectiveness.|
|Douglas bags: Held one week or longer for decay||Xenon||0.5/wk||Based on xenon half-life of 5.3 days;|
|Douglas bags: Released within one week||Xenon||1||Provides no reduction of exposure to general public.|
|Venturi scrubbers||ParticulatesGases||0.051||Although venturis may remove gases, variability in gaseous removal efficiency dictates adjustment factor for particulates only.|
|Packed bed scrubbers||Gases||0.1||Not applicable to particulates.|
|Electrostatic precipitators||Particulates||0.05||Not applicable for gaseous radionuclides|
|Xenon traps||Xenon||0.1||Efficiency is time dependent; monitoring is necessary to ensure effectiveness.|
|Fume hoods||All||1||Provides no reduction to general public exposures.|
|Vent stacks||All||1||Generally provides no reduction of exposure to general public.|
