Radiation Reported at Half Moon Bay Beach is not from Fukushima

The widely reported hot spot on a beach in Half Moon Bay California is NOT related to Fukushima Daiich (as has been speculated).  It appears to be naturally occurring (NORM) radioactive materials, primarily Radium 226 and Thorium 232.   Whether they are naturally occurring at that location or have been introduced there is not yet clear.   Stay tuned for more information as it comes in.  See story at Geiger Counter Bulletin
