Sorry, but no. X-rays have shorter wavelength than UV, much shorter than visible light. This equates to higher energy per photon, which is part of why they penetrate more than visible light (another way to look at this is that there are few electrons in most solids that can absorb a photon at such a short wavelength). Their resolving power, however, is much finer than visible; that's why x-rays are used to lay down the traces on integrated circuits that need to be smaller than a wavelength of visible light.
I wouldn't expect X-ray film to have less resolution than camera film, either. It's slow, which mean fine grain. Lack of sharpness, when present, is entirely due to the second emulsion on double-sided films -- the back side gets an exposure that's slightly diffused by the translucent emulsion on the front, like putting a frosted acetate over your negative and a clear one under to get an unsharp mask. If you could make the second emulsion's exposure and contrast enough lower than those of the front, you'd get a built-in USM with double-sided x-ray film.
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.
Does anyone sell it cut to 4X5 and boxed?
Mammography films are more likely to be single sided.
Just Google it!
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.
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.
Yes HR-U is double sided.
Today I paid $28 plus actual shipping and tax per 100 8x10 sheets.
I buy from Ebay vendor Xrayexpress
Cholenpot,
Sent you PM.
And now for something completely different...........

4x5 Fuji HRU Mic-X 5 minutes by Nokton48, on Flickr
My first Sinar Norma 4x5 photo in twenty five years taken yesterday. Fuji 8x10 HR-U X-Ray cut down to 4x5, Graphmatic Holder, 4x5 Sinar Norma 180mm f5.6 chrome Durst Componon lens, full key sun. This was exposure #6, two stops over ambient reading of grey card EI 50 TTL Sinarsix 1/15 @ Fll. Short development is stock Legacy Mic-X 5 minutes 68F. Cesco flat bottomed 8x10 tray, sheets developed singly. I did a sort of ring-around, varying exposure and development times. This is the lowest contrast version which I like.

Cool thing is this works out to about 7 cents per 4x5 sheet. I may load up the truck
Please post your large format X-Ray photos here
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
Ebay has them for a half dollar more. I assume you use a single bulb.
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.
