Re: NRC Licensing of Am-241

     Not all byproduct materials have an exempt quantity (i.e., 
     californium-252).  I have always assumed it is due to the high 
     radiotoxicity.  I would be interested to hear an official viewpoint.

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?
