I am working on 137Cs-based soil erosion estimation. For this purpose, I need to calculate the soil mass depth (Kg/m²).
Suppose I am using a box monolith with dimensions of 0.15 meters in length (L), 0.10 meters in width (B), and 0.05 meters in depth (the depth of the box) for soil sampling.
Should I use the vertical or the horizontal cross-section of the box for 137Cs-based analysis to estimate soil mass depth and convert Bq/Kg to Bq/m²?
