> One of the byproducts of their operation was a highly radioactive substance known as Thorium.
As a nuclear engineer, I find the use of "highly radioactive" to be an overstatement. Thorium and other TENORM [1] (and their secular equilibrium products) are among the lowest activity kind of radioactive thing there is. Otherwise, it would have all decayed away billions of years ago.

More radioactive = less stable = short half-life
Less radioactive = more stable = longer half-life
