Abstract
IN order to obtain radiographs of thin, easily penetrated materials, X-rays generated at only a few thousand volts (that is, Grenz-rays) have been used. This necessitates the use of a special Grenz-ray tube having a window transparent to the rays. In numerous cases, however, excellent radiographs of such materials can be obtained with the apparatus more commonly available in a radiographic department, by employing the secondary β-radiation emitted under high-voltage X-ray excitation from the lead intensifying screens which are frequently used in high-voltage radiography.
