Assistance Needed with OpenMC to Calculate Air Kerma and Mean Glandular Dose for Breast Voxel Phantom

[REMS R]

Hello everyone

I am a radiation protection student and need assistance with OpenMC. I have a breast voxel phantom and I want to calculate the air kerma to determine the mean glandular dose. I'm not sure what steps to follow to achieve this. Could someone guide me through the process?

Hello,

Could you add more details? what have you done up to now? Have you created the geometry and the source?

Hello,

Could you add more details? what have you done up to now? Have you created the geometry and the source?

The phantom and geometry are ready, and I have defined the source as photons with an energy of 30 keV. However, I am stuck at the step of building the mesh.

The creation of the mesh is done in two steps: first you create the mesh itself than you create the mesh filter using the MeshFilter function.

OpenMC offers various options for the mesh (RegularMesh, CylindricalMesh...).
For example here you can find the function for cylindrical mesh. It needs as input the radial, axial and angular grids. that are provided as list or arrays.
Once you have created the mesh you need to create a mesh filter.

In this tutorial they show how to use the RegularMesh function
