on the PDC video series, Bill Mollison recommended getting a Geiger Counter to aid with site selection and planning. Bill recommended one that was made in USA and that could be shipped internationally but I can't recall the details (I think it was $150).
Anyone have any recommendations of Geiger Counters that are good enough for us permaculturists?
