The actual "radioactivity" is due to nature uranium and thorium in the original phosphate rock. https://en.wikipedia.org/wiki/Phosphogypsum https://en.wikipedia.org/wiki/Phosphogypsum There are NUMEROUS places in the US that have similar or larger NATURAL concentrations of these. Pick any places in the Western US from So Cal to NV to UT to NM back to AZ!! Naturally NO WHERE in the article or any other references do they give actual numbers (e.g. Sv/hour) for the radioactivity. That actually matters a metric shxt-ton for assessing the actual risk. Without that it's nothing more than a boogie that appears after yelling "radiation".
