Abstract
A method and an apparatus for detecting the remote origin fraction ofRn present in a measuring site (Z) for the monitoring of dynamic phenomena inside the land crust, comprising the following steps: a) analysis of the measuring site (Z) in order to state a typical ratio betweenRn of local origin andRn of local origin; b) measurement, at preset time intervals, of alpha spectroscopy in the measuring site (Z) by a measuring chamber (); c) processing of said alpha spectroscopy in order to find the concentrations ofRn andRn present in the measuring site (Z); d) determination of the concentration ofRn of local origin by multiplying the concentration ofRn with the typical ratio; subtraction of the concentration ofRn of local origin from the concentration ofRn to obtain the concentration of the remote origin fraction OfRn.
