A dirty bomb is not a type of nuke. A dirty bomb contains radioactive material that is dispersed in a conventional explosion, the sole purpose of which is to spread radioactive material around an area.

I've got a little tritium filled cylinder on my keychain. It's neat.

The terrorists would have been smarter to steal from Target, or even better, K-Mart.

Well considering K-mart is for the most part no longer around like it used to be what would be the point?

Tritium is also a naturally occuring element... You drink thousands of tritium molecules every day.

They have a medium half life and arent very radioactive. A dirty bomb made of this stuff would be no more effective than a conventional bomb.

So those tin foil hats will finally come in handy?

Sounds like you know a liiiiitle bit too much about this stuff, hey? Been stealing some signs lately? I AM CALLING HOMELAND SECURITY.

There is NOTHING in the story about terrorists or dirty bombs.

Get a grip, OP!
He sees things we don't; you'd do well to listen to the OP. For example, the evil beloved patriot invasion!

Denying the plausible is not going to make it less plausible.

So what?

I could think of hundreds of plausible terror scenarios other than this, but that doesn't mean I should wet my pants and post my irrational fears on the internet every time I think of one.

Are you aware there are millions of sharks in the Indian Ocean, which could potentially be fitted with dirty torpedoes by ill-tempered Somali pirates, and unleashed into the Gulf of Aden, thereby threatening the world's supply of petroleum, bringing civilization to its knees?

Actually, not so insane. I have been tasked with monitoring NK activities for the past 18 months. In this bay they are currently training killer whales (they can tolerate the colds of alaskan waters best) to completely take out the shipping industry. They will be ramming fishing boats en masse. If you look closely at the one of the piers here you'll actually see a huge network of nets, where the killer whales sleep and eat. This is some scray stuff, folks.

A dirty bomb may cause panic and hysteria, but it is not really possible to make one which would actually cause loss of life. The reason is that when you disperse a small quantity of radioactive material via explosive, the radioactivity gets spread out so much that it is not possible to get significant dose from it, unless you were so close to the bomb that the bomb itself would kill you anyway. The only way to make a dirty bomb really effective would be to use so much radioactive material that it would kill the person gathering and assembling the bomb before they could deploy it.

They're also used in sights for pistols and rifles, the terrorists could be stockpiling guns....maybe.

The world's largest retailer said Tuesday it has checked all of its U.S. stores and removed any glow-in-the-dark signs that use tritium, a hydrogen isotope that, when used in the signs, has a radioactive strength similar to that of a smoke alarm.

The tritium gas in these signs is in a small quantity but the combined gas from 15,000 of them could be used to create a pretty deadly dirty bomb.

I do find it odd that so many of them are missing, I can see some falling off and then tossed in the trash instead of being disposal of properly, but 15,000?

You are total raging paranoid idiot.

Do you have any idea what tritum is used for? hint: It's not for a dirty bomb.

It's used to boost the yield of a fission reaction, which actually would make it a "cleaner" weapon, not "dirty".

You really need to stop posting idiotic threads like this.

True. What seems to be lacking is the understanding that even 15000 signs worth of material would be diluted by the explosion. It would have to be a very small BOOM to have any effect at all. Someone isn't thinking this through.

Well If one investigates the ammo we been using in Irag. Things get sickening really fast. Iraq has almost been made unliveable because of the depileted uranium ammom.
Its one hell of away to get rid of stockpiled depileted uranium. Our soldiers are getting sick also . You should see the birth defects there now. Its horroable. What have we allowed our government to do in our good names. Ungoldly acts of terrorism this is . Google find out. Sad but true.

IIRC each incident for improper disposal of concentrated tritium carries a substantial fine. Walmart has deep pockets.

If it's priced by weight, I'm going to buy an airship full of it then.

Huh? How do you make a dirty bomb out of a gas? It's hydrogen. It floats, it disperses quickly and doesn't hang around.

Trying to make a dirty bomb out of tritium is like trying to make a mess by pouring helium on the floor. Sure, tritium is radioactive but that doesn't change its chemical or physical properties. It won't lay around on the ground polluting the area, it'll dissolve in the atmosphere.

Completely hyped.

As a radioisotope, tritium is a very weak beta emitter and is not a significant health risk and (would have to be ingested in significant quantities), and short enough half life that it poses no long term environmental concerns. It's about as safe as a radioisotope can get: long enough half life to result in low emissions, but not so long that it sticks around forever.

As for fuel in a nuclear fusion bomb, that is also absurd. Again, too short lived, and as it is hydrogen, it readily permeates any known storage medium. In fact actual nuclear weapons do not use tritium at all because of these difficulties (the tritium is produced from deuterium and lithium at time of detonation).

Typical journalist who equates "radioactive" with "voodoo" and makes a big fuss out of nothing.

Depleted uranium is just that: depleted.

U-238 when vaporized into particulate matter is a poison just like lead, mercury, or any other heavy metal.

It has nothing to do with radioactivity, which would only result from trace levels of remaining U-235, and by the time you fired enough shells to have any measurable trace of U-235, the amount of non radioactive but toxic "lead dust" would be a much bigger problem.

The birth defects and all that kind of stuff are a result of classical lead poisoning, not radiation or unique to uranium shells in any way.
