Film Speeds

What film speeds does everyone usually use for iridium, cobalt and for x-ray. (ie; Kodak AA 1.8, Kodak T 2.5 , both when using Iridium). I would like to hear from as many people as possible and I will compile the results and post them here afterwards. You can email me at rt.film@sympatico.ca .

I think it would good idea if there was a guide for film speed selection based on actual indistry use and practice. So I would like to hear from the radiographers who actually use these numbers. I find the film speeds on the charts provided with the exposure calculators are not always what works best in the field.

I think this guide could help everyone.

Include any type and brand of film you like and say whether it is manual or automatic processing.

Thanks in advance guys!

Re: Film Speeds
---I've worked in RT for over 25 years and find that what works for me with Iridium Agfa D4 I use 4.5R, Agfa D7 I use 1.8 and Agfa D5 I use 3. With Kodak M I use 5.3R, T = 3 and AA = 1.8. It usually works well for me with manual processing
