Properties of Alpha Rays:-Alpha rays or alpha particles are the positively charged particles. A highly energetic helium nucleus which contains two protons and two neutrons is called the alpha-particle. Alpha particles have the least penetration power but the greatest ionization power. They cannot penetrate the skin but this does not mean that they are not dangerous. Since they have a great ionization power, so if they get into the body they can cause serious damage. They have the ability of ionizing numerous atoms I a short distance. It is due to this reason that the radioactive substance that releases alpha particles needs to be handled with rubber gloves. It should not be inhaled, eaten or allowed near open cuts.
