Jan,

There have been stories on the list about rolls of HIE left in hot cars for
several weeks before using and then only slight fogging being apparent.

When travelling in hot climates I always use a cool bag with a couple of
coolant packs that have been in the freezer.  In the USA it is always easy
to find ice - I tend to use that in Ziploc plastic bags inside the cooler
bag.

In the desert I keep the cooler bag wrapped in a couple of sleeping bags.
When travelling in the car I also place the cooler bag next to the air
cond. outlet and have it turned up to the max.

Exposed film is returned to the cooler bag and sealed in a separate Ziploc
bag to avoid any condensation problems.

X-Ray machines in airports - for the Western world hand baggage checks are
fine for IR film, and probably OK world-wide.  It's a different story for
luggage placed in the aircraft hold ie where all the suitcases are stored
during a flight.  Most airports now use a high powered X-Ray device which
zaps everything.  If you use a "lead" shield pouch for your films, the
X-Ray scanner  increases power until the contents of the pouch can be seen.

This is good for safety but will trash your film, so carry your film as
hand luggage and trust the X-Ray device.  Asking for hand searches in UK
airports tends to cause problems - ie they will not do a hand search and
you will attract unwelcome attention to yourself and your film canisters.
Usual problems are that a customs official will want to open a canister or
two to look inside before putting the film through the X-Ray scanner......

Carrying HIE in your pockets through the pre-flight security area is also
not recommended for the same reasons.  The metal canisters will set off the
metal detector and you stand the risk of a few canisters being opened for
inspection before they are put through the X-Ray scanner.



All the best,
