Re: Tuballoy

[COMSTOCK_DANIEL_L@em.lanl.gov]

    This same question was posed to me awhile back, and I found that there 
    is apparently a historical difference in the meaning of the term 
    "tuballoy."  In some older materials (1940's through 50's) it was 
    sometimes used to refer to depleted uranium, and sometime in the early 
    60's the meaning seems to change to mean natural uranium.  (I may be 
    getting this backwards).  Unfortunately I don't have the materials I 
    saw anymore, which gave very specific definitions of tuballoy and 
    oralloy - and the percentages given were different in the older and the 
    newer materials.
    
    I should explain that I'm a librarian and not a health physicist, and 
    if anyone has definitive word on the above I'd appreciate any 
    information available so I can document this for future reference.
