Not really. The emulsion is very soft when it's wet but doesn't produce pinholes that I've ever seen. Just handle with due care until it dries. Once dry it's just like any other film. I do use the normal amount of hardener in my rapid fix, however. I know many people use non-hardening fix for both film and paper.

I have in use the Typon Tyco 30x40 and 13x18 cm. It works fine.
It is of course an Agfa belgium production.
Typon cuts and configs the film in Sitzerland, I was told.
Speaking with Typon, they told me that they will quit the production of their blue sensitive film this or next year.
But they continue with green sensitive film..

It's only sensitive to blue or blue and green light, it is virtually insensitive to red, and IR has an even longer wavelength. Hence, IR sensitivity will be at best equal to sensitivity to red light (i.e. nearly not at all) and likely even less.

Thanks Ritchie. It was not only cheapest in the list but it came in a handy size, and having no previous experience... seemed like a good bet.
One thing - is it double sided, and if so, what do you do about it? I have read of stripping one side, but have no great idea about what this entails.

See this post in the current thread.
Re: Use of X-ray film: technical discussion with example images
Barnacle: I wouldn't worry about stripping until we have developing technique worked out and have negatives that have a normal contrast you would see in a conventional camera film. I am going to see how the scanned X-ray film looks up against some conventional film and proceed from there.
Re: Use of X-ray film: technical discussion with example images
Does anyone have personal experience with long term storage of (unexposed) x-ray film in the freezer?
Also, that's a good summation Sergei:

I don't know the DVG, and Typon doesn't say if doublesided or not in their data sheet, but I believe in double side, which not means a lot.

I don't like nor need to strip my film, except developing 30x40cm in rotation ( unfortunately no development at the backside).
So, for 30x40cm I switched to tray dev.
13x18cm works fine in rotation, but this depends on my/your tubes; I use an old Photo Union machine.
