kengrWatching NCIS LA, they just determined (maybe) that a fairly small box they are trying to track down is "full" of uranium.
Uh. No. Not possible.
Assuming it's enriched (only real reason for smuggling it this way), that much that close wouldn't go "boom" but it *would* be well over critical mass, and you'd have gotten a horrendous burst of radiation as you got the chunk close together, killing everyone in the vicinity. And continuing to do so for some time thereafter.
If you got them together faster, the reaction would be more energetic. Blowing the pieces away from each other.
[later]
Oh. It's supposed to be "powdered" and brown. That'd be uranium oxide. Somewhat safer, but...
[still later]
Oh lord, they are going to use it to "take out" a building by using the HVAC system to spread finely divided powder. Uranium oxide is a *lousy* choice for that.
It's not very radioactive. It's not toxic at all because it's insoluble. So the danger is the dust getting loidged in the lungs or the digest tract, and *eventually* causing cancer. Years, decades down the road.
You'd kill more people with readily available pesticides or any number of other toxins.
The writers are idiots.
