RE: Th-232 in scrap material

["Faillace, Ernie" <FaillaceE@TTNUS.COM>]

If you are unable to find radionuclide-specific concentration-based limits for re-cycled metal containing Th-232, consider using the RESRAD-RECYCLE code which was developed specifically to derive concentration guidelines for recycle of volume-contaminated material.  This computer model was developed by Argonne National Laboratory and is available for download from the RESRAD website at http://web.ead.anl.gov/resrad/home2/

Subject: Th-232 in scrap material

Dear Sir,

 

I would like to have information about the recycling limit of the Th-232 added aircraft alloys.

 

These aircraft debris is waiting in one of the official junkyard for selling.

 

If they sell,  it is not  possible to  know  the end users of final products. The products may be in use by public.

 

 

If you send to me any information about the activity limits for recycle and reuse of Th-232 added alloys It would be very appreciated.

 

 

Thank you very much for your interest.
