[ RadSafe ] Shielding of DEVICES

[Jim Darrough]

My two cents...

I would consider researching something called "neutron interrogation" before
I jumped at the screwdriver solution. These were not available during
Oppenheimer's reign.

     As Oppenheimer once responded to the question (How  would you detect
such a weapon), he wryly suggested that one needs a screwdriver to detect
such DEVICES. 
(i.e not some
sophisticated radiation detector(s)).  Hopefully USA and other  nation's
will use direct inspection of containers, shipping packages etc. to look for
nuclear DEVICES  directly ....

There is no instrumental solution to this problem.  Save for dismantling
every package (as Oppenheimer's remarks suggest)  before it crosses the
border, there will always be ways to circumvent any surveillance system.
The amount of time and money being spent on developing new super-duper
detection systems is largely wasted.  It would be far better spent on trying
to figure out why some people want to attack us, and then convincing them
not to do so.  (This of course would risk the possibility of learning that
some people might have good reasons for hating us.  It's a risk worth
taking, in my view.)
