Dear Experts

Please find attached the geometry cross-section.
1. RCC (A10) is cut by planes to divide it into regions, for Biasing (surface-splitting, increasing no. of photons per region)
2. RCC(A14) is also cut by same planes (as these are infinite), to divide for biasing. Is this the correct way ? OR, it should be done by making concentric RCCS as is done for RCC(A7). A10 & A14 for Axial points (Top of the shield).
3. RCC(A7) is divided into regions by making concentric RCCs - to calculate the dose rates in radial points.
Kindly suggest whether the regions are divided correctly.
Or, please suggest corrections.
The results I am getting are higher(by a factor of 1000) than expected.

Thanks in advance.
