Abstract
The threshold energy density for recording pulsed radiation lasting i msec on film is at least 10 -2 J/cm 2. We remember [2] that the sensitivity of films largely depends on the length of the radiation pulse. For pulses shorter than i ~sec the heating of the film may be regarded as adiabatic. For longer pulses the spread of heat over the film and in the substrate must be taken into account. The sensitivity of the film diminishes accordingly. Thus for a pulse 0.5 msec long the threshold energy density rises as high as ~ i0 -~ J/cm 2, which limits the use of films for recording low-energy radiation.
