I am new to the Geant4 community and before diving deeper in the code and it’s practicalities, I would like to have an idea of its capabilities. Especially, I am interested to make simulations similar to the “chem” examples series (chem1-5), which focuses on water radiolysis and the determination of G-values (primary yields) from 1 ps to 1 us. I can read in the documents that Geant4-DNA works with liquid water and I was wondering if we could modify this “material” to add 1 mmol/L of NaNO3, for example, so we have a homogeneous mixture of materials made of two (or more) compounds. Generally, how flexible is the setup of a material in Geant4-DNA?
The other question I have is about the particle. Is it possible in Geant4-DNA to output the G-values from an electron (<1 MeV), gamma-ray (1.1 MeV Co-60) or alpha particle (~4-5 MeV)?
Many thanks for any information you can provide,
