I’m reluctant to step in here where experts might have a different opinion, but it’s my feeling that x-rays and film (not moving image) should be treated like other photographic materials, especially like negatives.  My impression is that x-rays are negatives and should be preserved as such:  housed in PAT-safe materials (whether polyester or paper), stored flat if possible or if vertical then supported in a relatively tight environment so they do not curl.

 

If the “g banding” film is motion-picture film, it should be supported on a reel (preferably archivally safe plastic) and stored vertically.  (All media that are stored on reels should be allowed to hang from the reel instead of being stored flat, to avoid scoring edges of imperfectly wound tape or film).

 

For more information on visual materials, I’d recommend the IMAGELIB listserv (http://www.lsoft.com/scripts/wl.exe?SL1=IMAGELIB&H=LISTSERV.ARIZONA.EDU) or the Association of Moving Image Archivists site and listserv (http://www.amianet.org/).

 

The Northeast Document Conservation Center is also a great resource.  For instance, you can determine whether your x-ray film could be cellulose nitrate, with accompanying storage and preservation problems, from http://www.nedcc.org/leaflets/nitrate.htm, and view general guidelines for care of photographic materials at http://www.nedcc.org/leaflets/phocar.pdf.

Please post replies to the list.  

I have some film, unknown type, that is used to show g banding of chromosomes.  

FY - Definition of g banding:  

 

 

Technique for producing banding patterns in eukaryotic chromosomes. Bands are produced by staining with Giemsa stain after pretreating chromosomes with trypsin. Each homologous chromosome pair has a unique pattern of g-bands, enabling recognition of particular chromosomes.
