Response to X-Ray fogging
from Volker Schier (Volker.Schier@fen-net.de)
Two points: (1) The latest luggage scanners will inevitably fog film,
since their penetration is up to 300 times higher than the older
scanners use. Airport security DOES NOT tell which scanners are in
use so not to give any clues for potential smugglers etc.
(2) Some manufacturers seem to incoporate preexposed halides into the
emulsion to achieve higher film speeds. These halides inevitably are
far more susceptible to fogging.
