Study Introduction and Goals Methodology Drone Flight Data Analysis Conclusions Agenda
Regulations and Guidance
- 10 CFR Part 20, Subpart E
- NUREG-1575: Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM)
- NUREG-1507: Minimum Detectable Concentrations with Typical Radiation Survey for Instruments for Various Contaminants and Field Conditions
- NUREG-1757: Consolidated Decommissioning Guidance Guidance Documents
Proof of Concept and Key Questions for Analysis Did observed UAV paths differ from human planned paths?
Did survey deviation impact survey results?
Were radiological measurements from human and UAV surveys significantly different?

Q1 Results: UAV Paths vs. Human Paths?
Statistical equivalence between UAV and human paths Max slope deviation of 1.9
Q2 Results: Survey Deviation Impacts?
Velocity Variation
+/-0.3 m/s Altitude Variation Greatest for drone in all surveys Between 1.8-2.6 m/s for human and UAV Higher altitude surveys had less variation
Q3 Results: Significant Differences in Radiological Measurements?
Overall Conclusions UAV has potential in decommissioning Ludlum detectors work well in low and high altitudes Commercially available equipment able to perform surveys
Recommendations for Next Steps Optimize integration of radiation detection instruments Consider other radionuclides and detector types Address environmental condition variation in experimental development
