      • Have you measured emissions from your samples?
        Do the authorities ever check the old dumps & area
        around Wheal Trenwith or other St. Ives sites?

        • I use both a Geiger counter and a scintilometer readings vary a good specimen is around 5kCPS.
          around 300 micro sieverts. The background on the granite can also be high several hundred CPS
          Then of course there is Radon gas produced by the decay. Not sure any checks are made on mine sites.
