I second that emotion. I have been using natural potassium-40 as a
reference point to put these issues in perspective for along time. I
mean, the elemental spA of K-40 is nominally 850 pCi/gm. It rarely
fails to impress, e.g., women, when one explains to them that the
orange juice they give to their kids is naturally radioactive enough
that it can be used as a reference source to energy-calibrate
instruments (gamma spec).
