Do have a look at a gamma ray cascade,
from an energetic cosmic ray for example.
(already discovered before WWII)

You see energetic gamma rays creating energetic electron-positron pairs,
which produced more gammas, which produce more pairs, and so on,
until you have a particle shower that is easily detected,
