Bitumen has not thorium.
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.
United States has thorium reserves of approx. 160 000 t.
232Th has 142 neutrons and 90 protons and electrons.
The chemical symbol of thorium is Th.
The bitumen ductility test is conducted to assess the ability of bitumen to deform without breaking or cracking at elevated temperatures. This test helps determine the suitability of bitumen for use in road construction by evaluating its flexibility and durability under different environmental conditions.

Ceramic bowls for kitchen, with thorium, doesn't exist.
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.
United States has thorium reserves of approx. 160 000 t.
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%.
why bitumen is used

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.
Typically, bitumen and "asphalt" are interchangeable.
Bitumen is mainly used as a binding and waterproofing material, not as a fuel. It is widely used in road construction, roofing, bridge decks, airport runways, and pavement maintenance because it provides durability, flexibility, and resistance to water. While some heavy petroleum residues may be used as fuel in specific industrial applications, the primary use of bitumen is in infrastructure and construction. If you're trying to estimate how much bitumen is needed for a paving project, a bitumen calculator can make the calculations much easier. I’ve found BitumenCalcPro to be a useful free tool for estimating bitumen quantity, mix weight, and project costs.
