   @mcnees Long ago I worked on the Gargamelle neutral currents experiment at CERN where every 30 seconds we sent hundreds of millions of high-energy neutrinos through 18 tons of freon in a bubble chamber the size of a house. We ran this for several years.

   About one of those neutrinos interacted with the compressed liquid freon; the rest continued into space at ~ the speed of light.

   Though the risk was small, we didn't stand in _that_ beam.
