Methods of increasing the sensitivity of X-ray photographic films used in x-ray nondestructive testing

A modified developing solution is proposed suitable for developing X-ray films and method of additional flashing is used to intensity a latent X-ray image. Various types of films made in the USSR affected by a pulse X-ray radiation were studied. The effect of infectional developing and additional flashing resulting in the reduced exposure time is shown. Graphical curves are presented to illustrate the conception
