Standard protocol is warm water so that, (1) pores don’t close due to water being too cold and “hold on to” contamination, and (2) pores and blood vessels don’t open up (vasodilation) due to water being too hot and let contamination absorb faster.
That’s basic rad protection 101 stuff and there are numerous references that quote that protocol. Quick on-line search noted this protocol in US Dept of HHS, Rad Emergency Medical Mgmt and even the NRC Site Access Refresher Training, Chapter 7, (on the NRC website). Hope that’s useful.

Just checking if anyone knows of a requirement to have hot water in your personnel decon shower. I know it's the most efficient process, but is it required? I couldn't find anything other than the requirement for the decon facilities/shower (UFSAR, ANI. . .).
