Hmmmmm,  
 
    450 kg of HEU???? sounds like much too much.  Try  again.

If I got  the math right, about 450 kg of HEU is 1 Ci (37 GBq) with a dose 
rate of less  than 70 mR/hr (0.7 mGy/hr) at 1 meter. So from a radiation 
safety standpoint,  not that big a deal.

Subject: [ RadSafe ] Curiosity  query

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.
