Still need to work out a few problems with the Plutonium-Lithium battery I'm developing. Those pesky laws about who can buy the raw materials is making development difficult.

Psst! Wanna buy some uranium?

Radioactive isotopes also, at bargain prices!

PS: I'm SO disappointed that United Nuclear took down their .GIF that was on their main page for years.

Another addendum: what the book does report is the radioactivity of a few specific items found at the shed. The most radioactive was a vegetable can with a count rate of 50,000 CPM. Definitely radioactive, but to put this in context uranium glazed Fiestaware, which was sold to the public to eat off of as late as 1972, emits up to 30,000 CPM and yes, you can buy one of these for $39 today if you like.

The next most radioactive item was 6,000 CPM, one at 3,000, one at 1,500, and nothing else more than the low hundreds, not very radioactive at all.

United NuclearCarries pretty much all you would ever want, more than that kit had. Strangely enough, its not the radioactive things they find most dangerous. Its the rare earth magnets

WTF? Bulk uranium is NOT pyrophoric, it will NOT burn. Don't believe me? Buy a depleted uranium sample (I suggest http://www.unitednuclear.com/ ) and try to light it.

To actually make it burn you have to grind it into very fine dust. Just like iron or aluminium.

Two words:

Peltier chips.

The United Nuclear web site. Look for the ones labeled "EXTREMELY DANGEROUS MAGNET"!

Steal 20 pounds of weapons-grade plutonium and you have 20 of raw material that you need a Ph.D. and a lot of engineering knowledge to convert into a bomb

That is not the slightest bit correct. Like mots technical things, it is a smart cow problem. Practical designs for 'basic' nuclear weapons are well known. You can even get a t-shirt with one such design. It is the acquirement of material and enrichment processes that are hard.

Oh you can still buy them, just not in buckyball form anymore. Head over to the United Nuclear website and look for the 10 pound rare earth magnets labelled "Extremely Dangerous Magnet"! Remember, it's not fun if it's not labelled "extremely dangerous!"

No. Fuck this shit. I move that every citizen of the USA shall receive from the government one glock 9 mm pistol, one box of hollow point ammunition, one multi-watt laser pointer, one... no, make that TWO extremely fucking dangerous magnets, and a big fucking bucket of fireworks, to do with as they please. In one year, the survivors can get together and discuss additional regulation. :-/

So first we hear about funding problems at NASA.

Now we hear about NASA producing plutonium. So how are they planning on funding this plutonium operation? Hopefully it isn't by selling it on the internet*** to raise money ;^)

** Yes, you can actually buy radioactive isotopes on the internet. For example, from these guys here. Of course these guys don't sell plutonium, so NASA would be able to have a monopoly on that ;^)

I love that site. I always get a chuckle out of their "Looking for some URANIUM?" animated gif.

You may technically be allowed to sell these in some context, but you'll need a lot of luck to actually do so.

Enter The Dragon of all things nobody wants you to have. The don't have full bucky-sized sets, but you can buy the pieces for both buckyballs and buckycubes.

If I had a spare $22,000 I'd love to have a buckyball set made of these.

If you're an adult you don't necessarily have to have your fun ruined. Just get your rare off magnets off United Nuclear web site. Be sure to go for the ones labelled in red, "EXTREMELY DANGEROUS MAGNET". That's their code for "this is the fun one!" While you're there you can pick up some uranium ore and death ray parts.

Does not carry Sodium, but does carry many other fun products.

They probably got it on the United Nuclear web site. I'm sure there's a section under "Radioactive Isotopes" where you can get weapons grade uranium. Or maybe you actually have to call them for that...

You mean like this? And what isn't included in that kit you can mostly find at your hardware store (acids) or here or here, etc.

The problem isn't that we "got rid" of chemistry sets -- we didn't -- it's that nerds these days are more interested in playing WoW (full time job) and setting up websites to track their WoW status in their free time. Ok, that's hyperbole, but the information tech industries and their associated pastimes are definitely getting the majority of attention these days, not to mention money.

A couple of these http://unitednuclear.com/index.php?main_page=product_info&cPath=70_80&products_id=285 will completely destroy any data on any magnetic media.

Iodine isn't available without a license from the DEA.

Not here, or here, or even here.

In fact, I can only find 32 results in the first web site I thought to look in.

Looks like the system works!

hmmm, no mention of their brothel-oriented computer consulting services.

If you want to be more precise (and more expensive), you can order NRC-free isotopes from our friendly "local"* nuclear chemistry hobby shop. I think they were having some illegal harassment issues from the FBI a while back, but I haven't heard anything recently about it. Either way, you can still order and it's perfectly legal at the Federal level (might be worth a check of your local and state ordinances... and if they're not so favorable you'll need to decide if it's worth the risk of going to court to make the judges smack down completely unreasonable (from the scientific and evidence based point of view) "radiation safety" laws that tend to get passed to make some sort of impression with the voting public). They've also got some other fun items there, but not really relevant to the real concern voiced by the original question.

*Local is as local does; the "global village" if we want to dust of an archaic early internet phrase.

All Isotopes are sold by the microcurie (uCi)
( 1 microcurie = 2.22 x 10E6 disintegrations / minute = 2,220,000 cpm )

Normal sources are + or - 20% pf stated value.
For calibrated sources, add $120.00 and source will be + or - 5% of stated value and will include a calibration certificate.
Calibration is only available for gamma sources.

There are a few good small companies out there that make real kits for use.
I happen to run one myself. http://www.pansci.com/

For US based ones,
A good one would be United Nuclear http://www.unitednuclear.com/
Chemicals and chemicals.

I know, I know, CO2 laser is not even remotely like a microwave weapon, but it should be useful for other purposes.

You can get a lasers and related materials off of ebay, United Nuclear and Sparkfun at much better values.

D2O goes for about $70.00/100gm @ 'Ultrex' grade (99.999% pure), DOE has 580 MT up for bid, but it's contaminated with tritium; a bit more than your looking for.

Oddly enough though, Thermite is completely legal to purchase.

...United Nuclear (a US company) are still selling them.

And 1000 or so Slashdotters just found what to give their loved one for Valentine's Day.

And they even sell death-ray kits! Oh, I like these guys! http://unitednuclear.com/index.php?main_page=index&cPath=27_82

Tritium is not banned in the U.S.; I have one of the tritium keychains, a tritium compass, a gun with tritium sights... I don't know, there might be something else I'm forgetting. I have some old cockpit dials that contain radium. My smoke detectors are all radioactive (americium, I think). If I wanted to, I could buy uranium ore, trinitite, and more.

Heck, check this place out: http://unitednuclear.com/index.php?main_page=index&cPath=2_5

Note that they are an american company that sells to americans (and other countries, of course).

Naturally, they're banned in the US, because they're atomic.

I'm going to have to give you a [citation needed] for that one, on the basis that United Nuclear (a US company) are still selling them.

It really comes down to how inept the school officials have shown themselves to be. I'm an optimistic person but stories like this make me worry.

Just take a look at United Nuclear or this book to see some serious science fair projects, and imagine how some of those would of went down for the poor kid!

You can buy it here

You could help them build a processing plant to purify it and then eventually have your own little nuclear reactor. All the other kids in the neighborhood will be soooo jealous!

I'd first check with your neighborhood's nuclear proliferation by-laws. Buying uranium may risk sanctions from the other neighborhood kids who already have uranium. Your kids will no longer be able to play or share toys with the other kids in the neighborhood and will be ostracized.

That site is freakin' awesome! Previously, I had looked everywhere for a Death Ray Tube without success. That was until today.

Pfff, United Nuclear's site is nice and simple. Shouldn't be too much of an issue.

1,000 times less intense than the levels to which our naked eyes are sensitive

Hmm... what I was always told was that rod cells in the retina are sensitive to single photons. IIRC, that's also why spinthariscopes work. Now, sure, I understand that the probability of a random photon entering the eye hitting a rhodopsin pigment is fairly low, and the response could be inhibited by nearby neural cells, but it's still my understanding that you can see individual photons in very dark surroundings. So, is this threshold more of a "what people notice under normal lighting", or are these researching splitting photons somehow?

Having said that, a dirty bomb requires no expertese atall

Having said that, a dirty bomb requires nothing more than a few dozen smoke detectors, and if They didn't want to pay for it, the wal-mart down the street almost certainly has lower security than any of the facilities listed.

"The List" doesn't tell most people anything they couldn't already find out themselves if they wanted to (oh look, I can buy this stuff online).

Check out United Nuclear for insanely powerful magnets. Some of them are rather over the top in that they can break bones if you're not careful about moving them, but they also have lots of the small ones.
