These are other products that
can be produced along with the new element
Alpha Particles: 2 neutrons and 2 protons
They travel short distances, have large mass
Only a hazard when inhaled
Beta Particles: Electrons or positrons having small mass and variable energy. Electrons form when a neutron transforms into a proton and an electron or:
Gamma Rays (or photons): Result when the nucleus releases
Energy, usually after an alpha, beta or positron transition
