Lead screens for the protection of personnel in x-ray diffraction laboratories are usually at least 1 mm thick.
calculate the "transmission factor" (itrans./incident) of such a screen for cu kα, mo kα, and the shortest wavelength radiation from a tube operated at 30,000 volts.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
