Electron Penetration

[Fullhawking]

Depending on energy, how far will an Electron penetrate a block of acrylic? If you have any clue or where I could begin to formulate the equation thank you.

Well, I'd imagine that you'd need the ionisation
cross-section and the density of the material.
Or, for a full solution, some very complicated, abviously
energy dependent, solution of the wave equation.

Live long and prosper.
