1. An introduction to Gamma Rays and its use today!

2. Gamma Rays- wavelength and frequency
Gamma rays have the shortest wavelength of the spectrum
They also have the highest frequency
Wavelength < 10^-11 m
Frequency > 10^19 Hz

3. Gamma rays- “everyday uses”
Radio-therapy
Book conservation- kill mold and fungi
Gamma ray bursts (from stars)
Food irradiation
Gamma ray astronomy
Radioactive tracers
Find cracks in pipes and aircraft

4. Gamma ray bursts
Gamma rays have the highest frequency and therefore the highest energy of the entire EM spectrum
Gamma ray bursts are bursts of gamma rays that last from a few milliseconds to a few hundred seconds.

5. Gamma ray busts (cont.)
They can release more energy in 10 seconds than the sun will emit in a lifetime of one billion years.
Thought to be the result of exploding supernovas (a type of star)
