Why is there no "electron radiation"?

As I understand it, there is radiation that is made of particles (protons/neutrons/neutrinos(?)). But I have never heard of a radiation that would be made of electrons. There is probably an obivous reason for that, but I can not see it (yes, I tried google).

Electrons are emitted by beta^(-) decay of nuclei. They are also emitted by other kinds of nuclear decays like internal conversion, internal pair creation, and electron capture (via the Auger effect).
