Thanks. For example, if I would like to find out what percentage of the ionization in a gas chamber is the product of direct ionization (i.e. incoming electrons surviving the lead layer and knocking out an electron in the helium gas), what percentage is due to secondary electrons produced in lead and then propagating out of it and into the helium and creating ionization, what percentage is due to other mechanisms (e.g. Bremsstrahlung X-rays knocking out an electron, similar to the photoelectric effect), what percentage is due to whatever other shower particles created in the lead knocking out the electron in helium and creating an ion. There is a way to find this out, isn't there? I'm basically trying to look under the hood and find out what's going on.

Thanks, Neil
