Description
Summary:An application of the characteristics of infra-red storage phosphors to radiography is described, whereby the expense and trouble of x-ray film processing may be partially or completely eliminated. The properties of these materials to store x-ray energy for periods of time and release that energy upon exposure to infra-red radiation have proved practical for either temporary and permanent recording of the latent x-ray image. One distinct feature of this method is the complete removal of harmful x-radiation to the technician. The possibility of a new field of radiography in ``flash fluoroscopy'' is also suggested by the authors. Graphs and charts exhibiting the characteristic behavior of infra-red phosphors to x-ray energy are included as well as actual photographs and radiographs comparing radiography with phosphorography.
