radioactivity

Chemistry I was wondering if there are any materials that shed electrons as a form of radiation.

        Please bear with me if the terminology i use may be incorrect.  There are radioactive materials that shed neutrons as radiation.  I also remember hearing about protons being shed as a form of radiation.  But I don't know if there any materials that shed electrons as a form of radiation?  If such a material exists or can be produced, would it be possible to use these shed electrons as a source of electricity?

Electrons = Beta Particles (5.00 / 1) (#1)
by sciencebase on Fri May 26, 2006 at 05:38:30 AM PST
Yes, beta decay is the radiation of electrons (or positrons) by which a neutron converts to a positron and a beta particle and an antineutrino are released. Potassium-40 is an example of a beta emitter.
