Trace amounts of thorium and uranium are literally everywhere on the land surface of the planet. This is moot sans the "source that you quoted" and some stats and studies. For interest, Australia: https://www.ga.gov.au/bigobj/GA13928.pdf https://www.ga.gov.au/bigobj/GA13928.pdf India, Mali, Fiji, Africa, Americas, etc have similar trace amounts across their surfaces that are detectable from an aircraft 80m above ground level traveling at 70 m/second.
