What's the use of X-ray with angestrom wavelengh in imaging? Do you know of any good source to study more about that?
According to this site, the X-ray spectrum peaks at 60 keV with a secondary peak at about 68 keV. I believe most X-ray machines use a tungsten target. http://3dviz.ucsd.edu/~radiology_residents/Notes_files/CH052009.html http://3dviz.ucsd.edu/~radiology_residents/Notes.html http://courses.washington.edu/radxphys/PhysicsCourse.html
