skos:definition "Thorium containing not more than 10–7 g of uranium-233 per gram of <br/>
thorium-232. (From Ref. [2].)<br/>
Although the term 'unirradiated thorium' is used, the issue is not really whether <br/>the thorium has been irradiated, but rather whether the content of uranium-<br/>233 (a 'fissile material') is significantly higher than the trace levels found in <br/>naturally occurring thorium.<br/>" (en)
