The Alpha particle, also known as Alpha radiation or Alpha ray, is a positively charged particle that is released when radioactive materials decay. The mass of the alpha particle is due to the bonding of two protons and two neutrons. Alpha-particle is highly active and energetic helium atom.
- These particles have the lowest penetration strength and the highest ionization strength.
- Because of their high ionisation capacity, they can cause significant harm if they get into the body.
- They have the ability to ionise a large number of atoms over a short distance.
- Therefore radioactive compounds that emit alpha particles must be treated while wearing rubber gloves.
