RE: Information on U and Th in Tin Slag

["Tsurikov, Nick" <Nick.Tsurikov@iluka.com>]

Hello from Australia, Harry



In a sec I'll send you directly new (Dec.2003) IAEA technical document

dealing with all potential NORM things - I am almost sure that somewhere

on its 200 pages you will find either the information or the reference.

Technical Report series No.419: EXTENT OF ENVIRONMENTAL CONTAMINATION BY

NATURALLY OCCURRING RADIOACTIVE MATERIAL (NORM) AND TECHNOLOGICAL

OPTIONS FOR MITIGATION

If anyone else is interested - it is relatively easy to find on IAEA

internet site, or I can e-mail it to you direct (obviously, not to the

list - it's about 1.4 meg in size).



I also have a bit of info on tantalum here:

http://eneabba.net/tenorm/tantalum.htm 

(updates there should be ready in about a month)



Kind regards

Subject: Information on U and Th in Tin Slag



Radsafers;



I'm looking for information on the relative concentrations of Th-232 and

U-238 in Tin Slag and Columbite-Tantilum ores. An internet search has

come

up blank. There have been several CERCLA actions on C-T ore processing

facilities that might yeild some information (one might be the Elkem

Metals

Co. in Marietta, OH). Has anyone got access to the data from one of

these

sites?



Any information or reference sources would be appreciated.



Thanks in advance,



-Harry
