The technique of gamma-ray radiography has been used to obtain shadowgraphs of the internal metal framework (armatures) of several plaster and stucco figures. Both the technical and practical aspects of radiography of plasterwork have been considered, and while the gamma-ray sources ¹⁹²Ir and ⁶⁰Co may be particularly suited to very thin or thick subjects, respectively, a ¹³⁷Cs source of about one Curie is the most generally useful, and is capable of producing acceptable radiographs with stucco thicknesses up to about 50 to 60g/cm². Laboratory tests using a ¹³⁷Cs source showed that thickness sensitivities of 0.1cm of iron in 5.2g/cm² of plaster, and 0.2cm of iron in a 32. 5g/cm² thickness of plaster, were attainable. It has also been found that wooden armatures (density about 0. 7g/cm³) of diameter 1.4cm can be detected in plaster of thickness 15.6g/cm². Fieldwork has confirmed the results attained in the laboratory for wood and iron armatures; in addition features, such as cracks and density inhomogeneities in joints within the plaster, have been imaged. -- AATA
