I will explain my project in detail.
We are a team of computer scientists, geologists, and physicists. Our goal is to understand how radon propagates through the soil. But this is a high level. I will go into detail.
Radon is a gas that transports from soil to air and harms humans. It is a byproduct of uranium decay. I am using geant4 to understand if I have x number of uranium/radon particles at the bottom of my soil layers and how many radon particles (radon flux) will I get on the surface. So either I need to use radon particles in the particle gun or perform uranium decay and analyze radon through it(this I will decide).
The main thing for the project is detector material. Since my detector is nothing but 4-5 soil layers of earth. It is made of 4-5 concentric spheres with different radii. Now each sphere is nothing but a soil layer. I need to find the chemical composition of these layers. Now there are two ways I can put chemical composition:
- random approximation of different materials (Al, Mg, Si, C, O) found in organic soil.
- some logic to select chemical elements from the periodic table so that the elements selected affect most radon/radon decay/uranium decay. ( I am not able to find any logic)
I need to tell geologists which elements concentration from the soil I need to add to my simulation. They will give me value.
I am going by the second way. There should be something in the geant4 source code/ or some equation or some property of radon/uranium which can help me to understand which chemical elements affect the radioactive decay/radon traversal.
HELP::: Any input for my 2nd point will be a great help. The answer can be in terms of geant4 source code perspective or chemistry perspective.
