Everyone loves a good pdf. Right?

I have started working on a project that I hope will be helpful to anyone who may stumble across my blog. If you are an x ray student that you are absorbed in information so please take this for what it is worth. I plan on adding a few pdf. files for you reading and studying enjoyment. What is a pdf. you say? For those of you who may not know. A pdf. file that is a file that is easy to read. If you really want to know more follow the embedded link and enjoy. If you already know what a pdf. file is thank you for humoring me. One more thing about pdf. files for the newbie is that you will need to have adobe acrobat reader installed on your computer. this program gives you read only rights to the pdf. files for free. (Link will be provided.)
With that said I have planned to turn some of my more helpful study guides into public information. Of course nothing in these files will be copy righted material but thay just might be helpful. In addition to my classroom study guides I have prepared a few of my own documents that I will also place on this blog. Of course these will all be radiography related.
If you have any similar information that you would like to contribute please feel free to contact me and we can work something out. Or if you have any suggestions as to a topics for a pdf. file that you would like to have developed you can contact me via e-mail or here in the blog.

The Roentgen Report


Physicists at Argonne National Lab in Illinois are making rainbows from x-ray photons. No small task considering X-ray wavelengths are some 10,000 times shorter than those for visible light. Physics Diagram



PHOENIX - A test of an X-ray security scanner that can see through clothing, even taking clear pictures of the human body along with concealed weapons, has been delayed until early this coming year at Phoenix Sky Harbor International Airport.

Critics say the high-resolution images are too invasive, and the American Civil Liberties Union has called it a virtual strip search.



ITHACA, N.Y. -- In an unusual collaboration among scientists and humanists, a Cornell University team has demonstrated a novel method for recovering faded text on ancient stone by zapping and mapping 2,000-year-old inscriptions using X-ray fluorescence (XRF) imaging.

Rectifier - X Ray Technologist Blogs.


I have created a new section of links under the heading "Rectifier." No rectifier no x-rays. So I felt it was only fitting to redirect readers and pay homage to other similar blogs. A number of these blogs have executed what I only had good intentions of doing. Namely documenting thier way through the program. So if you really want to get a feel for how the program takes a toll on you I suggest you give these blogs a gander. In fact I have to go back and do some reading myself. One real nice thing about the variety of these blogs is the variety of locations and experience. You will see blogs from various different states written by students and technologists.


True
or False
  • The rectifier is placed between the step-up transformer and the x-ray tube to change alternaing current to pulsating direct current?
