Greetings. Somewhere along the way, I seem to recall hearing that
heat shrink tubing was made of an irradiated rubber material.
Does anyone out there know if this is true? If so, what is the
material irradiated with? I would assume it would have to be a gamma
source, otherwise there would be residual radioactivity, which I
assume is not present with heat shrink tubing?!

Any reponses by mail please--I'll summarize info. Thanks.

Correct, plastic tubing is irradiated to induce cross linking, then
stretched. When heated, the crosslinks cause the material to pull back
to its original shape.

The radiation comes from electron beam tubes, essentially large X-ray
machines.
