Most electronic flash tubes use xenon, based on this
Flashtube - Wikipedia, the free encyclopedia xenon has a spectral peak in violet (UV starts at .4 microns), and probably puts out significant amounts of UV radiation. But the glass used to make the tube can block UV radiation, and usually there is an additional glass lens over the flash tube.

General Xenon Flash and Strobe Design Guidelines A camera flash should have the current density needed to be efficient at 5500 K, and produce a relatively uniform white light at that colour temperature, and would be considered equivalent to blue sky daylight.
