Abstract- The purpose of this experiment was to show how isotopes, when exposed to high intensity neutron sources, will become radioactive until they decay back to their normal state. These isotopes return to their state through the release of beta particles, or - 10β (the same thing as an electron, only formed in the nucleus). When the isotope, in this case aluminum, becomes exposed to the extra neutron, it becomes a different isotope, in our case silicon, plus the beta particle, causing it to be radioactive. In order to get rid of the radiation, each radioactive element has a half-life, symbolized by / t1 2 , or the amount of time it takes for half of the radioactive material to decay. For my half-life, I found it to be 2.484 minutes. The actual half-life of aluminum though is about 2.25 minutes, giving an error of roughly 10.4%.
