Techniques {x-ray absorption} can find heavy atoms among lighter atoms, such as crystal impurities, gasoline lead, broken bones, barium enemas, body iodide, and steel and plastic faults. Absorption depends on molecular mass, density, and thickness. X-rays can come from electrons that hit metal anode at 80,000 V. X-rays hit target, whose ionization energy allows high primary x-ray absorption {absorption edge} and which emits lower-energy x-rays {secondary x-ray}. Detection is by film.
