Forum Digital Camera : SLR Flash characteristics

What effect does bounced flash have on unit-emitted UV radiation?

A) If flash is bounced off room ceiling
B) If using a unit such as the Lumiquest Softbox or the Lumiquest Ultra Soft ( the latter has a diffusing screen in front
of the bounce backstop ).

Or, do we have to worry about UV when using a professional flash unit such as the Nikon SB800?

This is of interest to me because flash is forbidden in photographing some museum interiors because of feared UV damage to color of paint, fabric, etc.

Thanks for you help.
