Use of X-ray film: technical discussion with example images

Has anyone determined around how long Fuji super hr-u lasts on average after expiration? Trying to determine if I should cut this film to size and put it in the fridge or just keep it out in my ~70-80F darkroom.

I did, however, discover that the small, red AC safelights sold on Ebay are NOT safe with Fuji HR-U Xray film.

There is practically no difference between the steps, but the ruler I laid over one edge was perfectly clear.

I am not saying these don't work for other applications, but be aware of my experience if you are thinking of using them for X-ray film.

James, I purchased this red LED rope and agree; they work great with absolutely no fog for Fuji HR-U.

Now if I can only get the scratching under control. Using a Pyrex caserole dish because 6.5 x 8.5 film hangers are rare to non-existent, but even then I get abrasions.

Exploring a way to 3D print these, but it will be a while so I will cut it down to a smaller format for the time being.

If you like sweets go into a supermarket and look for something like this: https://www.profipacking.ro/caserole...t-si-prajituri
You have to find the packaging that is flat. Some are reinforced at the bottom and not in the lid. There you can get the lid. You also should experiment with the transparent and the black version and find out which is softer.
I got one type where the lid is transparent, not reinforced by profiles and of soft material.
You an buy than that and it practically comes free, after you eat the cookies.

First I bought different other foods, but no matter how good I cleaned them, grease did not go completly away. But the sugary residues clean up completly.

Important is, that what will become the bottom of your tray is not reinforced by a profile. Completly flat is best, but hard to find as they have somehow to give strenght to the flims foil these recipients are mad of. If the profile has no hard edges and the material is soft plastic, than it also will not scratch.

Cut some 1 year expired Fuji Super HR-U for my 120 camera.

I use polystyrene "trays" (the foam type) after i consume the food contained :) They are light to use and soft for the X-ray films.
