Transcript of X-rays in WW1

By: Michala Penninger X rays in WW1 Origination and Beginning Stages The X-ray The x-ray was invented in 1985 by Rector Wilhelm Conrad Roentgen in Germany. He saw that a barium platinocyanide (salt mixed with PtC4N4^-2) screen when he made negatively charged electordes in a Crookes tube. X-rays are made when high energy electrons hit a metal target. Low energy rays are blocked by a filter so only high energy rays go through the patient and hit the film. Another piece of film under that keeps to x-ray from fogging up. The bone calcium in the patient acts as the metal that the high energy electrons hit when a piece of film is on the body, and that makes the picture. How it works To WW1: the x-ray was important to WW1 because it helped see the internal injuries that the soldiers had, which saved lives(for the ones with injuries that could be healed), and also the infirmity level/time dropped for soldiers because their problem was found out sooner.
To America and history: the x-ray was important to history because it was a painless and non-invasive way to find internal abnormalities. The x-ray could help broken bones, tumors, dental decay, and foreign bodies(things that were not supposed to be there, such as a piece of a bone staying in the arm after it was broken off. Significance/Impact: A fact that I found interesting in the research of this topic was that when the man who invented the x-ray started working on it, he took six weeks straight out of teaching and doing anything else, and for six weeks practically devoted his life into inventing the x-ray. Favorite Piece of Information Some important things to know about the x-ray are:
-High energy and low energy electrons hitting metal are what takes the picture
-Many lives are saved by discovering the internal damage done with an x-ray machine
-Tumors and internal bleeding would be much harder to locate and fix and would take a longer amount of time without the x-ray
-Fun fact: X-rays can not get through Earth's atmosphere, so if an astronaut wanted to detect an x-ray it would have to be through a space telescope
The x-ray got it's name by first being called X-radiation because Roentgen did not know what it was called. What I Learned:
I learned that the making of the x-ray took a lot of time and effort, and also science with the reaction between the film, metal, and high and low energy electrons. Also, it saved the lives of many soldiers in WW1 and still people now. X-rays can be used for broken bones, internal damage, dental damage, etc. Sources: -www.aip.org/history/curie/war1/htm
