Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Scattering?  Shine a flashlight into clean water.  How much of the beam is scattered?

Most of Cherenkov radiation is UV, so there is bound to be inelastic scattering.

Best of ET discussion,or why i stand on ET.

As one never having experience with Cherenkov radiation eye defer. (Eye am amazed that someone here has such experience.)

It was deep blue--which would scatter as blue light scatters.  

Or are you asserting I was seeing scattered--and down shifted into blue--UV light?

If the scattering is inelastic, it should reduce the frequency.

Yes, inelastic scattering means that the wavelength changes. That is, the UV photon gives kinetic energy to the particle it scatters on, and turns into a blue photon.
