Yike! Where do you get the cadium iodide and cadmium bromide for this process?

And are you aware of the health and environmental issues with cadium salts? They're the reason for some of the emulsion changes and product deletions at Kodak and Ilford in the last couple decades -- it was impossible to reformulate particular products without greatly altering their properties, if the cadmium used in making them was eliminated, and prohibitively costly to meet worker safety and environmental requirements if the cadmium was kept in the process.
