  1. RadiationPower Point presentation by From the Class Class 422-002MC. Higgins and Demitri Lazarev “The decay and the spread of Emissions”

  2. Outline TOPIC SLIDES • Alpha Emission • Beta Emission • Positron Emission • Electron Capture • Gamma Emission FINISHING SLIDES • Conclusions • Bibliography

  3. Alpha Emission • What is Alpha Emission? Alpha emission is when a radioactive nucleus of an atom submits a helium nucleus out of the nucleus itself, leaving the old nucleus with the mass going down by 4 and the atomic number going down by 2. (2 neutrons and 2 protons “spit out”)

  4. Beta Emission • What is Beta Emission? Beta Emission is when a radioactive nucleus undergoes a procedure that has one neutron of the nucleus split into an electron and proton changing the atomic number by 1 and the mass staying the same.

  5. Positron Emission • What is Positron Emission? Positron Emission is when a proton is “converted” into a neutron combining with an electron, reducing the atomic number by 1 and leaving the mass the same.

  6. Electron Capture • What is Electron Capture? Electron capture is when an atom has an unstable number of protons (more than electrons) and it picks up an electron, having positron emission coming into place, having combine the proton and newly electron, changing it into a neutron leaving the atomic number reduced and the mass staying the same.

  7. Gamma Emission • What is Gamma Emission? Gamma Emission more known as “Gamma rays”, are a type of electromagnetic radiation with very short wave length and very high frequency, may able to cause damage.

  8. Conclusions • Equations To wrap up this project, there are five types of Nuclear Emissions, Alpha, Beta, Gamma, Positron, and Electron. The equations are above. Nuclear decay is how long it takes for a nuclear substance to decay.
