Re: NRC Licensing of Am-241

["Eric L. Darois" <daroiel@naesco.com>]

     This appears to be a confusing issue but not just for Am-241.
     
     It is my understanding that the quantites listed in 10CFR30.71 are 
     used to establish exempt quantities mainly for source distributors but 
     ONLY if they have an exempt distribution license.  For example, a 
     licensee cannot simply declare a 5 uCi Cs-137 source "exempt" unless 
     it is distributed under an E distribution license.  The same is true 
     for the inverse: a licensee cannot send a non-licensee 5 uCi of Cs-137 
     unless it is a source distributed as exempt.  Otherwise, this would be 
     a handy way of reducing one's stockpile of radioactive material; one 
     exempt quantity at a time.
     
     Therefore, the exempt quantities listed in 30.71 applies as a guide to 
     someone licensed to distribute exempt sources and also applies to 
     individuals non-licensed to recieve sources distributed as "EXEMPT".  
     The licensed conditions may impose additional restrictions.
     
     For Am-241, there is no pre-determined exempt amount except as the 
     original message noted in 30.15.  Therefore, this isotope is not 
     distributed in any amount as an exempt quantity.
     
     Again, this is how I understand the process, are there other 
     interpretations ???

Can anyone tell me why Americium-241 is not listed in 10CFR30.71, Schedule B?
     
I know that it is mentioned in 30.15 at 0.05 microcuries for sources in 
ionizing radiation measureing instruments.  
     
Since it's not listed, does this mean that "ANY" amount of Am-241 must be 
licensed by the NRC?
