I thought mamography film is always coated only on a single side of the support, but it seems not to be always so. (Thy speak also of doouble coating and I first thought it could be that the one side is coated with two layers of emulsion, but it seems not.)

    Kodak states:


    What means for us the difference between primary and secondary emulsion?

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

    This thread is 12 years old, I think I read it all

    The only way to learn ANY film is to test for yourself

    I process KODAK Carestream, Fuji X-Ray double sided and single side on hangers, Rodinol 1/100 68 f active agitation 7 minutes, water stop, TF5 fix

    Hope this helps

    I have always bought X-Ray ANALOG film from this Iowa distributor ZZ Medical, they only sell in date fresh film

    They have changed to only case lots of KODAK aka Carestream

    I just bought my last supply of X-Ray from ZZ, a case of FUJI ANALOG
    for a project

    All Medical X-Ray seems to be going out of production, as Digital takes over, some industrial uses survive

    If you are just testing, buy this https://www.zzmedical.com/analog-x-r...-ray-film.html

    All X-Ray requires a careful touch when wet

    Since it is so cheap, play with it and try everything

    I cut it down to many sizes, including Hasselblad

    This pictogram is printed onto the back of Carestream (and Kodak) X-ray film packs. Can somebody explain to me what it means? Obviously I have never opened a pack. What does avait me? Are the sheets individually packed in a foil that needs to be opened? And than put back in the bag?

    I think it means to close up the pack when done. It just shows a light tight way to fold the package. I’ve never used the Carestream stuff, but Fuji does not come in the plastic bags that are so common with LF photo film. Instead it comes in a sealed paper pack. You tear off the top to pull film and it doesn’t have as much extra as the plastic that film comes in, so you have to be a little careful how you reseal the bag.

    I use scissors

    but it is designed to be tear off

    watch out as it is easy to slide the whole 100 sheets out

    I bet X-Ray film was then transferred to a dispenser

    I use a paper safe

    I have bought some 18x24 cm and 24x30 cm. Will this fit without problems in our casettes? (And in which ones? Metric system or inch?) Or are they nomimal sizes for the X-ray casettes?

    I also bought some dental panorama film. It came in two sizes (same film) 15x30 cm and 12,7x30,5 cm (this one has mentioned in paranthesis: 5x12 in.). So it seems imperial and cm sizes were made.
