Description
A radiographic technique that uses a plane beta source to produce an image on a radiographic film. Since 1967, beta radiography has used a source plate composed of a thin polymethacrylate sheet labeled with radioactive carbon-14. This isotope emits pure beta particles of low energy (150 keV), which can penetrate a maximum of 10 inches of air, 0.3 mm of skin or a sheet of paper (Kushel). The technique is performed by first layering a sheet of film, emulsion side up, then the paper to be examine, covered with the beta plate. A glass weight or vacuum is applied to press the layers together and minimize air gaps which deteriorate the image quality. The image corresponds to the mass per unit area of the paper or material being examined. Thin layers of organic ink or paint usually do not appear on the radiograph but mineral ink or paint absorb the beta particles and so appear on the radiograph. Beta radiography produces high quality and high contrast images of watermarks and other texture characteristics of paper. Due to legal issues concerning the use of radioactive sources, electron transmission radiography is a possible substitution technique.
