All I know about this I learned from Ron Laskey's articles, e.g.
Meth Enzymol 65:363-371, 1980.

The cardboard cassettes are available from Sigma (among other suppliers)
but really need to be clamped between two boards to be suitable for -80 C
storage.  Compared to the cost of the intensifying screems <- Freudian
slip, but apt :-) screens, the cassettes don't seem so bad.

Hope this helps
Jim
