history and process of radiation therapy?

[kats]

Hi, I am taking a Chemistry class as a pre-requisite for nursing school. I hope to start in January. Our teacher offered a chance for 50 bonus points by writing a paper relating to Chemistry. Since we are studying nuclear chemistry right now, I figured focusing on this topic would help to prepare for our next test too. Anyways, I am having a bit of difficulty finding scientific information regarding radiation therapy. I found that it started around 1897 and some of the first pioneers were Wilhelm Alexander Freund, Henri Becquerel, Marie Curie, and her daughter Irene Joliot-Curie. I also have my text book and an article from Time magazine regarding radiation therapy for breast cancer. The problem is that most of the web sites I have found are for patients so they tend to simplify things quite a bit. I am sure this is to ease their anxiety, but I am not finding a lot that I can use for this paper. Any suggestions on where to go to learn more would be appreciated. Keep in mind also that I don't want it to be too scientific that I would have to have a doctorate degree just to understand it. Thanks in advance for any suggestions.
