For USM to work properly, the backside second emulsion would need to be a soft positive image.
I have stripped that backside emulsion after development, and the image is a bit sharper looking... and grainier. If you read the densities before and after stripping, the stripped version has exactly half the density. My understanding is the second emulsion is only there to increase the speed, or the sensitivity of the film when exposed with screens.

Seen the title I am utmost disappointed. No X-ray exposure...

Yes, I really expected that you had added an X-ray apparatus to your stuff.


Sir, you flatter me. Thank you.

Can someone point me to which films are single sided? Fuji HR-U which is cheap and plentiful, is this single or double. What Fuji line is single coating if any?

Mammography films are more likely to be single sided.

Is there a emulsion name or producer for it? If I google Mammography films I get a bunch of info about the process and photos of the x-rays but no names of the film or places it's sold.

Just Google it!

It's not that simple anymore. Depending on device and location and even time the results will be different. You think I'm asking because I haven't tried google already?

Check out Carestream, for one. You can find info on spectral sensitivity, film curves, which is single or double-sided, etc etc. Also, I believe I posted two vendors you can get film from. ZZ Medical, and CXS Online.

Thanks.

Google diving brought me info that said mamo film is generally one sided emulsion.

Cheapest film I've found yet is 8x10 Fuji Green HR-U film 100 sheets for about $36 shipped off Ebay.

Yes, usually mammography xray usually is single-sided. The Fuji Green HR-U is great stuff, and you cannot beat that price! If you find you like it, it's a good idea to stock up on it. Who knows how much longer it'll be around, or will stay cheap.

Knowing my luck it'll be gone as soon as I learn it and then price will skyrocket.

The Fuji HR-U is doublesided?

And now for something completely different...........

Kodak Min-R Single Sided Mammography 18x24cm
by Nokton48, on Flickr

This is single sided 18x24cm Mammography XRay I found a while back. I do have one Sinar Norma 18x24 film holder, so this will make nice sized contact prints.

The big bonus is that I can cut it into four 9x12cm to fit my European holders and cameras.

25 cents a sheet for single sided 18x24. Looks like these came from France.

Nope not yet

8x10 Norma has not seen any action for a while. I'm working on it

I make RC B&W prints and scan those

On the subject of safe-ing a room for cutting up X-ray film. I have a safelight but I'm unsure if it's ok for film.

Here's a photo of the thing, I found it at a garage sale in Buffalo many moons ago.







I've used to for paper with no issues. I guess I should swap out those 25w GEs for something a little lesser? Maybe chuck this in a corner far far away from where I plan on cutting.

The Lowes $6.98 3 watt LED should do the job? Three watt bulbs are not that easy to find!

You should then have about what I have (which I know works) depending on how much filtering that red cover provides.

I keep mine at least 6 feet away from cutter and trays with no fogging high speed film so far. It also provides a very decent amount of light

Nice photo! I ran out of Fuji HRT and got a box of HRU. I ran into the same problem with high contrast and short development times. It's really constrasty stuff. I processed it in Rodinal 1:100 at 68° for 6 minutes. I pre-wet the film first. Anything red and oranges will become darker since it's not panchromatic but green sensitive. I'm experimenting processing it in POTA for about 6 minutes.

Ebay has them for a half dollar more. I assume you use a single bulb.

Loading Up The Truck Fuji XRay
by Nokton48, on Flickr

OK HR-U is going to work for me in the larger formats. So I am loading up the truck as I have no idea how long it is going to be available. Not bad at $28 a box.

400 8x10 sheets of HR-U plus the hundred I already have. Hopefully a lifetime supply. While I was at it I grabbed a hundred sheets of RX-N, which is the blue two sided high speed Fuji XRay film.

Great fun ahead I predict. I loaded four 4x5 Graphmatics, and four 2x3 Graphmatics, with HR-U this morning.

Mainecoonmaniac,
Thank you for your contribution regarding the HR-U.
Anybody with first hand experience please contribute
And also Thanks Andy for your many contributions.

It sounds like more testing is in order, I like the idea of using yellow and green filters with HR-U.
The Freestyle Legacy Mic-X replenished seems to be doing the job for me so far.
