Can Terrorists Build a Nuclear Bomb?
kjh1 writes "Popular Science is just chock full of good articles this month. One in-depth article addresses the question many are afraid to acknowledge is a possibility - can terrorists acquire the raw materials and then deliver a nuclear bomb? A good read that explains the difficulty in doing all of the above, while pointing out calmly that it is still possible." From the article: "Most experts with whom I spoke said that a nuclear terror attack is plausible but not inevitable, and that there's no way to precisely gauge the odds. 'I don't think the public ought to lose a lot of sleep over the issue,' says nuclear physicist Tom Cochran of the Natural Resources Defense Council. "
I'm a physicist. I know how hard it would be for an unskilled, untrained bunch of terrorists to build a bomb from scratch. I don't lose sleep over this.
However, why would terrorists want to even try this? Assuming they wanted a real nuclear detonation rather than a dirty bomb, isn't the possibility of purchasing or stealing an intact, complete weapon of more concern? Reading this doesn't exactly give me the warm fuzzies about the former Soviet Union. And remember, the Pakistanis and North Koreans have the expertise, know-how, materials, and a desperate need for hard currency.
It's worth noting that the size (i.e. yield) of a nuclear weapon terrorists would be likely to acquire/build would be very low (maybe a few kilotons). And while the destruction sowed by such a device would be larger than that of a plane or truck bomb, it would not destroy a city.
First the bomb is likely to be detonated at ground level, or a few stories up in a garage. This limits the blast damage significantly. Assuming an urban environment, tall buildings would also limit the devices blast effectiveness. US and Soviet bombs of the Cold War were several *mega*tons, and were detonated several thousand feet in the air. With a terrorist's bomb you will not see the massive air burst followed by a blast wave that topples buildings and vaporizes people for miles.
The most dangerous effect from small bombs detonated at ground level is fallout. This would likely be enhanced by the very structures that limited the blast radius. Surrounding buildings would force radioactive dust and debris up, making the likelihood of winds blowing the fallout over a larger area higher.
Indeed, a nuclear detonation in Manhattan would destroy several blocks and kills tens if not hundreds of thousands of people. Such an event would be devastating to our economy and to the lives of millions. IMHO this is something completely different from Cold War style nuclear scares. A nuclear war between the US and Soviet Union would have killed hundreds of millions of people, billions in the after effects. Here, the likelihood of you being personally and directly harmed by a terrorist nuclear weapon is relatively low when compared to the effects to the economy on a national (and global) scale.

US Media to citizens:
"We in the US media wish to shield you from this world. We bring you only news stories from your own country,
The top two stories on CNN. The headline and the one on the top right.
1. Blasts rock Baghdad, kill 20
2. Putin: Iran not developing nukes
Top stories on Fox news:
1. Attacks Target Shiites in Baghdad
2. Putin: Iran Has No Nuke Plans
The US reports plenty of world news. I know while any post that says (something in the US = bad) is modded up here, this is just silly. When the Tsunami happened, it was 24/7 Tsunami coverage here. When the Russian Schoolchildren were held by terrorists it was basically 24 hour coverage. Sorry if CNN doesn't report soccer scores from around the world, but America doesn't care about trival stuff from around the world.
unless the story furthers the goal of making you even more freightened. Besides, who wants any real news about other countries?
The BBC is available in America, the fact is people are more interested in their local news than world news. Sorry if this bothers you. It isnt' a media consperacy though, it's just a free market economy reacting to what people want.
They don't even have NASCAR in those strange lands!
I guess you are trying to generalize about southerns now, since NASCAR's following is mostly in the more rural section of the country.
Do you really care about what happens in a place without NASCAR, unless they are IMMINENTLY ready to attack! Like SHARKS, and ASBESTOS, and POWER LINES!!! News at 11!!!!!!"
Please. Yes, people care more about trivial events in their own country than trivial events around the world. When something big happens, it is covered ad nausem.
