PRESENT STATUS OF CONTACT MICRORADIO- GRAPHY The resolution possible is that of the optimal resolution of the light microscope, i.e. about 0.2 micron. The histochemical weighing technique based on contact microradiography permits the estimation of the dry mass weight of cellular structures as small as 10 to the -12th to -14th power grams with an error of 5-10. Contact microradiography with monochromatic X-rays now permits the quantitative histochemical analysis of certain elements such as P,S, and Ca with relatively good accuracy, and it seems likely that this technique can be extended successfully to estimations of C, N, and O. Qualitative microradiography has found wide use in studies of capillary circulation, mineral salt distribution, metallurgical research, and other fields. Author
