Dear Geant4 users,
I am simulating a radioactive decay chain of Ac225 inside a biological cell. When using the Geant4-DNA physics module the daughter isotope (Fr221) doesn’t interact with the surrounding medium. There is no EM physics for Fr221 in Geant4-DNA, so it doesn’t loose energy. Do you have any idea what I can do in order to simulate the whole decay chain with Geant4-DNA (I need Geant4-DNA for scoring the strand breaks of DNA)?
Kind regards,
Mikhail
