[ RadSafe ] Curiosity query

[JPreisig at aol.com]

Maury, Dog,
 
     You're asking hard questions today.  Search  alamorgado  .  
 
     The amount of Uranium and/or Plutonium in such a  bomb, and its 
enrichment level are items of information not usually openly  discussed.  The 
radiation shielding for such a device is no big deal,  since
U and Pu are primarily alpha emitters.
 
     Have a good one.    Joe  Preisig

Can  anyone tell me or suggest a link to description of the size and 
weight of  the radioactive components of the Hiroshima bomb?  Also would 
like to  know weight and size of the shielding required to handle this  
material.  How did they load this material onto the USS Indianapolis  
without lethal irradiation of handlers?  Am wondering if these  answers 
would shed any light on what would be required to attempt a  practicable 
so-called dirty bomb if not a practicable nuclear  weapon.

Seems to me that terrorist groups would be hard pressed to  handle a 
nuclear weapon even if any of our opponents saw fit to give them  one 
...?  The implication to me is that a dirty bomb of any serious  yield 
would not be feasible?

Thanks for  comments.
