Abstract
Summary
1. Autoradiograms of irregular surfaces of mollusc shells and curved surfaces of bone canbe made without difficulty by applying sheets of emulsion removed from Eastman Industrial X-ray Film, Type A. The emulsion is developed while on the object, facilitating the localization of radioactive areas, and maybe removed for densitometric measurements if desired. 2. Darkening of the emulsion may occur as a result of direct contact with sutures and certain definite regions of non-radioactive bone. Accordingly, in making autoradiograms by this method control exposures on non-radioactive bone are required to evaluate this effect.
