In summary, depth dose calculation in Geant4 is a method that uses the Monte Carlo simulation to determine the absorbed dose of radiation in a material as a function of depth. This is important for predicting radiation absorption in applications such as radiation therapy and protection. Factors such as particle type, material composition, and dimensions can affect the accuracy of the calculations. While Geant4 can be used for various materials, it is crucial to accurately represent material properties for reliable results. The accuracy of the calculations can be validated by comparing with experimental data and other simulation tools.

TL;DR Summary
Depth dose calculation in Geant4
I want to calculate depth dose in Geant4. I will use the TestEm11 example for this. How can I convert the output values to Gy?
The TestEm11 example does not provide direct output in Gy, as it is designed to provide simulated results in terms of energy deposition (edep) in a given volume. To convert from edep to Gy, you need to calculate the absorbed dose using the linear energy transfer (LET) of the particles. This can be calculated using the following equation: Dose (Gy) = edep (MeV/g) x LET (keV/µm).
