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

I'm from the Czech Republic, I see the following ortho films (I don't want a blue-sensitive film) in stock here and around (I don't want a blue-sensitive film):
Fuji UM-MA HC
Agfa CP-G
Agfa HDR-C

Is there a major difference?
And last question...with Fomapan 100, I sometimes shoot at 400 with cameras that do not allow a longer exposure, and the film can handle it well. Is something like this possible with x-ray film?

Thanks.

===================

I have written a PDF of my experiments with X-ray films.
However - I seemingly can NOT up-load it on this "web-site"....

It tells of the selection, Cutting, exposures, and Development processes.

Thanks, I appreciate it, I sent an email.

Please try again---
I did not receive it....

I've done some new test on development, 18x24 X-ray film.

Pyro-501 home made and Cibachrome drum. Dilution 1:500, using 0.2ml/100ml water or even 0.1ml/50ml water (insulin syringe) with continuous rotation for 30minutes, 25C, a simpler variation of this:

Pleased with the density and contrast of the negatives - good scanning and good contact prints.

I use mamo film and the antihalo dye cleans nicely and used also double sided X-ray MXG (2017 expired) - no scratches (not 100% sure of even development)

18x24

Attachment 245191

the full size

Also a lot of 18x24 cut in three 6cm wide stripe in various 120mm folders, same development. I got two images of 6x9 or three 6x6 or four 6x4.5

I tried 2 sheets overlapped and got bad results, some undeveloped areas.

I need to try exposing 3.5 X 14" X'Ray Pano

I have Film Hangers that size

I may tape strips in 11X14 holders

I always want an odd experience

What about X-ray film used in the producing industry for nondestructive checks? (I guess for weldings, defects in materials, etc.) From time to time they appear on sale.

Agfa Structurix is the one I know. It is easy to find at specialized resellers for industry.
The point is that in European Union hyper regulations don't allow sale of products deemed for companies (industries) and professional sectors (medical for instance) to private persons, so the visibility of such dedicated resellers is limited to the professionals inside the given sector.
Implementation of EU regulations varies by country, and sometimes a branch reseller/shop doesn't care and sells to private persons small amount of an item. Here in Norway, which follows strictly EU norms it's impossible because you must provide a company VAT number, majority of shops in France too (local SIRET number or EU VAT number) and Germany is (in)famous for sticking to whatever regulation.
Sometimes it has to do with the level of tax control on business, with requirements for strictly conform accounting data, partly related treasury, partly related traceability of whatever transaction.
The other day I contacted a business in Germany selling a range of medical x-ray films. When the contact knew I was not a business she didn't even reply back.

by now some british seller offers Structurix on Ebay, but because it is outside EU, there is the tax wall, making it more expensive.

if in your country you don't find a reseller who can be and is relaxed with the company/private regulations, then the nearest area, included very lax attitude with postal tax declaration (quite some will declare as gift, so dodge import tax), is Ukraine, for instance for medical film https://medshop.com.ua/rentgenologiy...entgen-plenka/ Otherwise Russia but need to have a russian card. Then China, but from experience it's hard to find a reseller accepting to sell small amounts.

I have still a stock of x-ray blue, green, mammographic. My preferred LF size is 13x18/5x7 and I shoot sometimes a lot, so x-ray is very convenient. It's invaluable when testing repro lenses and old brass lenses, etc. So I'd like to buy more of it but yesterday instead I bought a roll of aerial film, 76m in 24cm. This too from a 2-hand source, some seller in India. It's silly: I bought from India 2-hand an item manufactured in Belgium, but that I have no possibility to buy directly as an european.

today I contacted again Astrum/Svema about their current stocks and prices.
Before I bought from them bulk Svema 100 in 61,5mm and 13x18 sheets.
I didn't pay attention to everything on their product list. But then I have noticed their x-ray films:

rentgenplivka texnichna is labelled RT-4 and RT-5. These remind namings of FOMA industrial xray films under name INDUX, R4, R5, R7:
https://www.foma.cz/en/catalogue-ind...-ray-films-153

so I asked the SVEMA/ASTRUM guy and he answered they do sell FOMA xray technical film, also cut at desired size. ...

I bought a box of 5X7 Industrial X-Ray

It has way too much packaging

It is meant to to be exposed inside a heavy paper envelope

X-Ray!

Outside also had Lead cover

So it was you who overbid me on eBay.
I am curious to see your results.
