Radiation is energy in the form of waves.
 * __OUTLINE__**



The nucleus has too many protons which causes overload, then when it gets too overloaded a Helium porton is released.
 * __ALPHA EMISSION__**



When the nuetron to proton ratio is too big in the nucleus and causes it to be unstable. Then a nuetron is turned into a proton and an electron. Finally the electron is dismissed.
 * __BETA EMISSION__**



__**3H1 > 3He2 + 0e-1**__

When the nuetron to proton ratio is too small. A proton turns into a nuetron and a positon and the positron is released.
 * __POSITRON EMISSION__**

When the nuetron to proton ratio is too small (again). The nucleus captures an electron, which turns a proton into a nuetron
 * __ELECTRON CAPTURE__**

When the nucleus is at too high an energy. The nuclues falls to a lower state of energy, then releases a high energy ray known as a photon or gamma ray.
 * __GAMMA EMISSION__**

All of these types of radioactivity are similar. They all have something wrong with the nucleus. Whether it is a strange ration between proton and electrons or too much energy. They all emmit a particle through this problem with the nucleus. This partical is the radioactive ray that can cause damage to you. They all also have an equation for it, so it can be studied relativly easy among different scientists.
 * __CONCLUSIONS__**
