Alpha Particle
 scroll 
Positively charged particle emitted by various radioactive
materials during decay. It consists of two neutrons and two protons,
and is thus identical to the nucleus of a helium atom. The rest mass
of the alpha particle amounts to 6.64424·10-27 kg,
or 3.7273·109 eV. Alpha radiation is the radiation
with the lowest penetration potential of the three radiation types (alpha, beta, gamma
radiation). Alpha radiation can already be stopped by a sheet of
paper and is only dangerous for living creatures if the substance emitting
alpha rays is inhaled or ingested with food or enters wounds.
