Elton,

Am also using 2/98 dated 120 with no base fog problems.  It is kept in a
fridge after purchase also.  Developed within 24 hours of exposure using
Ilford HC.

Have loaded in bright sunlight with very little shade - no fogging :-)

I would guess that the film has not always been kept in a fridge - either
that or the ozone layer above your house is very thin and solar radiation
is bouncing around your house.

New XRay machines for aircraft luggage?

Try a roll of in date Konica using your normal processes and see if that is
also fogged....


All the best,
