Radioactivity

Our topic was about Radioactivity.

 In radioactivity, obviously there is radiation; is the process of emitting energy in forms of waves or particles. Radiation is produced when particles interact or decay (emission of particles from isotopes).
Fact: A large contribution of radiation is from the sun (solar) or from radioactive isotopes of the elements (terrestrial)

  The three types of radiation are:
    

 *Alpha - is a kind of decay that gives off protons and neutrons, resulting in a different substance. Alpha particles are positively charged.
   
 * Beta- is a kind of decay that gives off positron and electrons, thus makes it negatively charged.

 *Gamma-rays- is a high energy light particle.Gamma-rays are the released energy after alpha and beta decay. It is also the deadliest ray.

Half-life is how long it takes for half of a sample of a radioactive substances to undergo radioactive decay.
