Microradiography of contract type using monochromatic divergent beam is reported. The beam involves only K_<α1> radiation the wavelength of which is a little shorter than the absorption edge of the element to be concerned so that the radiograph obtained is very sensitive to variation in concentration of the element. By using Cu K_<α1> radiation the contrast due to a difference of concentration of Mn in single crystal of NaCl wasobserved, which could not be observed by using polychromatic or partly-monochromatized X-rays by Ni filter. From these contrast the difference of atomic ratio of Mn to Na atoms was obtained quantitatively. The difference of the atomic ratio was observed clearly to a small amount of 6.2×10^<-4>.
