An Autoradiographic Effect


WHILE using X-ray films in another investigation, autoradiographic effects were obtained from many ordinary substances or mixtures of them. Materials such as zinc metal powder alone or mixtures of metal powders in a medium such as dried ‘Glyptal’ varnish were used. Such mixtures were put in holes in wooden or plastic blocks and the films attached to the blocks with drawing-pins or tape. A cardboard separator was used around the edges of the blocks to keep the films out of contact with the materials, leaving an air-gap of about 1 mm. Exposures of 48 hr. were generally used.
