Nuke Q&A / Interpreting MARSSIM: Final St...

Last post by aewa11 - Yesterday at 08:13

I'm planning a final status survey for a small concrete pad (approx. 10m x 10m) used for temporary storage of potentially contaminated components. Scans identified two isolated beta-gamma hotspots (each <100 cm²). The rest of the area is background.

Following MARSSIM, I'm using a grid-based approach for the Class 1 area.

Sticking Point: For the two small hotspots, does it make more sense to:
Treat each as its own separate survey unit (SU) due to their distinct, elevated activity?

Looking for practical experience on how this is typically justified in an FSS report to satisfy regulator expectations.
