    The leading producers of coated fabrics were among the first to see the many advantages of beta-emitting radioisotope measurement and control of coating weight and thickness. As early as 1950, tire manufacturers began using nondestructive, noncontacting radiation weight or thickness gages employing beta-emitting radioisotopes, commonly referred to in industry as beta gages. Today, for example, all tire producers in this country control rubber coating of tire fabric with these beta-emitting radiosotope measuring systems. The same may be said for practically all producers of plastic-coated automobile upholstery. Many coaters of other types of fabrics have also adopted this relatively new technique because of its many advantages. These techniques have also been utilized in the unsupported film industry.
