"Industrial Sectors with TENORM...The improper disposal, re-use, and recycling of diffuse TENORM has led to circumstances resulting in contamination events and unnecessary public exposures....
Table 6. Estimated annual production rates and average 226Ra concentrations
Material/Waste Stream
Production Rate (metric tons per year) & Average 226Ra Concentration, Bq/g (pCi/g)
Metal mining and processing 1.0E+09 0.18 (5)
- Rare earths 2.1E+03 33.3 (900)
- Zirconium, hafnium, titanium, and tin 4.70E+05 1.59 (43)
- Large volume industries (e.g., copper, iron) 1.0E+09 0.18 (5)
...The metals extraction industry typically generates ... less than 0.1 billion MT (.11 billion short tons) of smelter slag. ....Measurements made at a tin smelter showed 238U concentrations up to 1.59 Bq/g (43 pCi/g) and 232Th concentrations up to 0.7 Bq/g (19 pCi/g). Gamma survey measurements at a tin smelter showed radiation levels in slag storage areas ranging from ~0.087 to 4.35 uSv/h (10 uR/h to 500 uR/h), with average levels less than ~0.522 uSv/h (60 uR/h).

" My suspicion (I have no facts in this case) is that much of what came from Texas and Louisiana may fit into that broad definition of "NORM" (normally occurring radioactive material) that - though naturally occurring - becomes more concentrated than its natural "dose" on oil field pipe and drilling equipment. I confess, that if I even knew exactly how that material was regulated federally [it was not regulated] and managed in the States of Texas and Louisiana, I have forgotten it over the past decade.."....

Heather Mcmurray 's work exposing the poisoning of 1000 square miles around El Paso by Asarco smelter through what the EPA & US DOJ said was illegal burning of illegal hazardous/radioactive wastes 1991 to 1998. We have never been told what actinides are present from illegal Asarco actions(see 73 page 1998 conf. for settlement purposes only DOJ EPA Asarco doc,10/06 nytimes) see "Asarco secret document"
