Bitumen has not thorium.
Thorium is not expensive; for thorium dioxide (99,99 %) the price is cca. 0,1 USD/g.
Common compounds of thorium: thorium dioxide, thorium trifluoride, thorium tetrafluoride, thorium tetrachloride, thorium triiodide, thorium diiodide, thorium tetraiodide, thorium nitrate, thorium oxalate, thorium carbide, thorium sulfides, thorium nitride, thorium oxinate, etc.
Approx. 50 USD/pound for thorium dioxide (99,99 %).

Thorium-234 has a half-life of 24.1 days. How much of a 100-g sample of thorium-234 will be unchanged after 48.2 days?
United States has thorium reserves of approx. 160 000 t.
why bitumen is used
When not mixed with clay, about 0.02% (depending on the type of thorium compound)of ingested Thorium is absorbed into the body but since Thorium is strongly adsorbed by clay, the absorption of ingested Thorium mixed with clay soil is negligible, much less than 0.02%.
The half life of thorium-232 is 1,405(6).10e10 years.
Mustek manufactures a variety of packed bitumen products. Their bitumen products are produced at the Europoort refinery in Rotterdam, Germany. They produce 3 types of bitumen: penetration bitumen,oxidized bitumen, and hard bitumen.
