Anyone can walk into any welding supply business and walk out with 50 or 500 pounds of Thoriated welding rods [2% thoria by weight which can equal many pounds of thorium oxide in 500 pounds of welding rods]. Thoriated welding rods can also be purchased on eBay. The activity of this much Thorium oxide is a real concern.
>From a reference: "The compounds of thorium are very active. Thorium oxide surpasses even metallic uranium in activity." Of concern in this regard for ThO2: No control on purchase. A totally exempt isotope, and the potential for significant contamination. And people are worried about a few exempt quanity check sources? Bizarre.
