[ RadSafe ] Gamma background radiation at ground level

[Brennan, Mike (DOH)]

Several years ago I talked with an engineer working for a below ground
coal mine, who was investigating using radon concentrations as a way of
detecting shifts in the rock that might indicate an impending collapse.
I don't know if anything came of it, but it was an interesting idea.

"In the SF East Bay Area hills I always thought that the background 
measurement might be a way to to assess soil rain water saturation and 
thus the potential for slides."

Also earthquakes (maybe)

Much work is being done on this.
