Quantitative radioautography can be made more accurate by exposing a standard source with multiple intensities for the same time and to the same photographic emulsion as the specimen. The absolute radioactive reference source can be made of several active monolayers. The activity of the specimen in areas as small as 30 microns can be measured by means of a microdensitometer comparing the densities of each specimens radioautograph with the calibration curve furnished by the standard source.
