Hi everybody,
I was wondering if somebody could help me find a chart or a table with electron attenuation lenghts or crosssections in matter. I've searched the Internet insideout but even if I would find something, it would be articles that you have to pay for . Still it seems a normal and trivial information to find somewhere. So if somebody has a handbook or something with that information  please let me know. Thanks a lot. Mike.

Perhaps you need the bethe bloch equation?
Not sure how useful it is for electrons. i don't know if its still used but as i recall it allows you to adjust certain constants that are typical of the soild you are using and calculate the the velocity damping. (or at least the energy loss as a function of distance) You could maybe use it to calculate something yourself. Or do you need much data or already publsihed results to compare to? Is the CRC a possibility?
