Uses of Gamma Rays

So from the links I found before I decided that I'd use cancer treatment as a use of gamma rays because that's pretty cool.

So this time I started searching "how do gamma rays kill cancer cells" and I came across a couple of useful websites,

http://www.cancer.gov/about-cancer/treatment/types/radiation-therapy/radiation-fact-sheet

This explains pretty well some of the problems of treating cancer with gamma radiation. It does seem to focus on a lot of the medical stuff into a lot of depth.

http://www.cancer.org/treatment/treatmentsandsideeffects/treatmenttypes/radiation/radiationtherapyprinciples/radiation-therapy-principles-types-of-radiation

This site is better at explaining that gamma rays are ionizing because they have a lot of energy, and that other types of waves don't ionize because they have less energy. It is the ionizing that damages DNA and caused the cells to die.

I also found this cool YouTube video that was really useful at helping me understand cancer treatment a bit better.
