HOW ARE THEY USED?
- Gamma rays help to kill certain cancer and tumor cells.
- Gamma rays coming from space are mostly absorbed by the earths atmosphere gamma ray astronomy was undeveloped until possible for detectors to go pass the earths atmosphere.
- 4 nuclear reactions Nuclear fusion, fission, alpha decay, and gamma decay

INTERESTING FACTS
- Gamma rays are the most energetic form of light an are produced by the hottest regions of the universe
- Gamma- rays have the smallest wavelength the most energy of any other wave in the electromagnetic spectrum
- Gamma- ray bursts can release more energy in 10 seconds than the sun will emit in its entire 10 billion year life time
