A Preliminary Report on the Use of Radioactive Materials in Lithographic Research Work.

The successful use of radioisotopes in other fields of research suggested that they might prove valuable in studying the fundamental nature of the lithographic process. A brief explanation will be given of the preparation of radioisotopes in a uranium pile, and how a typical radioisotope such as P32 disintegrates. The equipment which has been acquired at Glessner House for radioisotope work, will be described. Methods for treating the lithographic plates with radioactive materials and the use of control plates to aid in the interpretation of the results, will be explained. Some of the early results of this lithographic radioisotope research program will be mentioned and a possible future program will be outlined.
