It's worth talking a bit about range.
A 20 keV electron ranges out in air after about 1 cm.
An 80 keV electron ranges out in air after about 10 cm.
A 300 keV electron ranges out in air after about 100 cm.
Most of the electrons observed in particle accelerator collisions are 
between 10's of MeV and 10's of GeV. At these energies, the most common 
energy loss mechanism is the creation of a shower or secondary cascade, 
which can easily penetrate a good fraction of a meter of lead.
