RE: Nova - Dirty Bombs - London Scenario question



However, there is another aspect to the suicide bomber scenario.  Suicide attacks involve the attacker either dying in his own explosion or in returned fire.  Either way, the attacker's death is immediate - no lingering, no suffering.

 

But a dirty bomb requires a large source that has to be acquired, then transported to the place where it will be made into a bomb.  Then there's the bomb fabrication process, loading the bomb into the delivery vehicle and transport to the destination.  As this process evolves, a single case of acute radiation sickness is likely to derail the whole thing.  Suicide bombers who see that radiation sickness is a relatively lengthy, truly ugly way to die will likely have second thoughts - cooperation will become a problem, etc. Trying to manage radiation exposure involving such a large source so that none of this happens begins to confound the necessary efforts to do all this inconspicuously.

If I may suggest some other aspect. 

1.  Consider that the ones who assemble the bomb are not those who deliver it.  Therefore the driver may not have symptoms of radiation sickness as he is in the front and the source is near the rear doors.

2.  To assemble the bomb, the source capsule is cut using a high-speed circular saw and the CsCl powered is dumped in a fragile (plastic bag) container that will rupture easily.  The assemble could take less than 15 minutes.

Come on Stewart.  I am sure that if you wanted to make a radiological bomb, you could do it.

Stewart's comment:

The scenario NOVA dramatized last night involved a whole lot more Cs-137, or
a source with 74,000 GBq of Cs-137 [2000 Ci] as I recall them mentioning.
For a point source of Cs-137 this equates to about 6.6E6 R/hr at 1 cm. If
the terrorists spent 1 hour at say 2 feet from this unshielded source [??? a
wag assumption] in fabricating the bomb and transporting it they would
receive about 7,000 R whole body.

comment:

a) However suppose terrorists instead 2 feet he keeps the source in a Van,
1.5 m away - the dose drop to about 300 R/h

b) Terrorist do not care for his life, today countries as Israel and USA
are forced to witness the hair's breadth of difference between the ability
to prevent a terrorist attack and the ability of the terrorists to blow
himself up and to be succeeded in his mission.
