Sample quote: 'When David's Geiger counter began picking up radiation five doors from his mom's house, he decided that he had "too much radioactive stuff in one place", and began to dissasemble the reactor'."

      Also, machining the explosives for a nuclear weapon is very critical. They have to be just the right shape and size, and you wouldn't believe the tolerances.

      And as I recall, the radioactive particles emitted by Uranium are alpha (okay, it's been a long time, so I'm guessing), which can be stopped by a stout pair of pants. It's gamma particles that are the nasty type... which sounds about right for plutonium.

      No one said that he built a "reactor" (To wit: Wordnet: "2: (physics) any of several devices that maintain and control a nuclear reaction for the production of energy or artificial elements [syn: nuclear reactor]") but that he had in fact stimulated a nuclear reaction. It was not self-sustaining, nor externally sustained.

      As for the sources of fissionable (and convertable) material...

      David learned that a tiny amount of the radioactive isotope americium-241 could be found in smoke detectors. he contacted smoke-detector companies and claimed that he needed a large number for a school project. One company sold him about a hundred broken detectors for a dollar apiece.

      and

      The mantle in gas lanterns, the small cloth pouch over the flame, is coated with a compound containing thorium-232. When bombarded with neutrons it produces uranium-233, which is fissionable. David bought thousands of lantern mantles from surplus stores and blowtorched them into a pile of ash.

      To isolate the thorium from the ash, he purchased $1000 worth of lithium batteries and cut them in half with wire cutters. He placed the lithium and thorium ash together in a ball of aluminum foil and heated the ball with a Bunsen burner. This purified the thorium to at least 9000 times the level found in nature, and up to 170 times the level that requires NRC licensing. But David's americium gun wasn't strong enough to transform thorium into uranium.

      and

      It was slow going until one day, while driving through Clinton Township, he says he came across an old table clock in an antique shop. In the hack of the clock he discovered a vial of radium paint. He bought the clock for $10.

      (I can only assume by "hack of the clock" they mean "back of the clock - nice proofreading there)

      and

      The NRC's Erb had told him that "nothing produces neutrons from alpha reactions as well as beryllium." David says he had a friend swipe a strip of beryllium from a chemistry lab, then placed it in front of the lead block that held the radium. His cute little americium gun was now a more powerful radium gun.

      and

      David had located some pitchblende, an ore containing tiny amounts of uranium, and pulverized it with a hammer. He aimed the gun at the powder, hoping to produce at least some fissionable atoms. It didn't work. The neutron particles, the bullets in his gun, were moving too fast.

      To slow them down, he added a filter, then targeted his gun again. This time the uranium powder appeared to grow more radioactive by the day.

      Interesting that it doesn't say what the filter was made of. Anyone know what material you'd use?

    The reasonable thing to conclude about this story is that David Hahn is a real person, who managed to make a radioactive mess, and probably successfully extracted some radioactive elements, but very much did not make a nuclear breeder reactor.

    One of the people mentioned in the story is David Minnaar, who works for the Michigan DEP. He's certainly a real person; see Antique crock turns out to be radioactive and Michigan DEP site with his e-mail address (minnaard@state.mi.us) and phone number (517-335-8197).

    So at the minimum they're real people, and can certainly easily confirm or deny the story or its details, unless they refuse to talk about it, which would be a bit silly.

    There was a long cross-posted thread in alt.folklore.urban, sci.physics, and sci.skeptic at the beginning of last year about this, Some good posts:

    The existence of David Hahn is plausible; that he accomplished anything resembling a nuclear reactor isn't. It takes a lot of math and physics to build a safe nuclear reactor, but it only takes a pile of radioactive material to get radioactive readings. As extracting elements is pretty much the most basic task in chemistry, and it's all the guy had to do, I believe that he could have done it. Calling what he made a nuclear breeder reactor is pure journalistic hoo-hah (or more charitably, gross exaggeration)...actually, the journalist merely implies that's what Hahn did, by using the phrase "breeder reactor" over and over again. A good lesson in the difference between what's actually said and what's implied. He may have had a dangerous nuclear pile, but that's far from a genuine reactor.

    Remember, this is 19th century chemistry that he was doing, and had the advantage of extracting radioactive materials from already purified sources.

    Sorry for the confusion, LionKimbro. I really should have been more specific. I should have said "lifetime allowable dosage of radiation for a person working in a US Navy nuclear specialty." I'm sure there's a "government recommended maximum civillian dosage," and it's set at a very harmless and generally un-reached number.

    Here's a little background on the Navy nuclear field:

    The enlisted and officer personnel that actually work on the naval reactor systems (ratings of MM, EM and ET, plus officer billets) go through a special school at Naval Weapons Station Charleston in South Carolina.

    • First, one is trained in their specific job duties. ("A School")

    • Second, you go through 'Power School' -- principles of nuclear physics, what makes these things work, how, and why they're dangerous.

      • While in Power School, you are scanned to determine exactly how much radiation you have absorbed thus far in your life. (Some call it "Hugging the Box.") From that, the Navy knows how much more exposure you can receive before you are no longer allowed near radioactive sources.

    • Third, you go to 'Prototype' where you get to play with a working reactor, just not on a working vessel. There are 3 of these in the US, 2 here at NWS Charleston, and 1 in Ballston Spa, NY.

    As far as exposure goes, I'm not going to get into the exact specifics & numbers. (I'm not sure exactly where 'common knowledge' stops and 'confidential information' starts.) Numbers don't matter in any case, as I don't have exposure readings for Petty Officer Hahn.

    The point is: The Navy has chosen a number for the amount of exposure you're allowed. David Hahn exceeded this number before he enlisted. Therefore the Navy will not allow him to work in a situation where he will receive artificial additional exposure. The Navy is not interested in medically retiring him and handing him a disability check because something turned cancerous, all because he went near a reactor... again.

    The Navy does understand the risks involved -- and they certainly minimize their exposure as much as they can, both to radiation risks and litigation risks!


    Petty Officer Hahn is quite famous here around NWS Charleston. Every Power School class hears about the 'Radioactive Boyscout.' Curious about what he's doing now? He's an 'airdale' -- he works on the flight deck of an aircraft carrier.

    Computers are devices. Programs are instructions. Instructions, last time I checked, are speech. Or is telling you to "Clean your room" a device because it is an instruction? How about x=(-b +/- sqrt(b^2-4ac))/2a? 'rm -rf /'?

    The manner in which I constructed the sentance, emphasizing functionality over readability proves nothing. Speech that is meant to be used and not just read is still speech. Call it a device if you want, but, boy I can still look at it, print it out, read it, understand what it "says." It even still smells like speech. I don't care what you call it. You can't prohibit speech. DeCSS is a complex series of instructions. Text. Protected.

    Fair use is common to countries without such constitutional guarantees. It originated under British common law, and was retained after the colonies seperated. It predates the first amendment.

    Clever but irrelevant. We're talking about what's illegal in the US. The constitution is paramount. If it weren't in the constitution I wouldn't be arguing with you, regardless of when fair use originated or where else it is found.

    There are plenty of laws prohibiting distribution of information

    Name one. And it can't be a copyright case, or be justified by compelling state interest--because those are constitutional justifications. Even NDAs are limited by the first amendment. I can contract away my right to speech and still exercise it!

    Grow up and face reality. "Shouldn't" is a more realistic word to apply to government than "can't."

      Take, for instance, the second amendment. It states in simple terms that the government can't disarm citizens (the right of the people to keep and bear arms shall not be infringed). No mention of "reasonable for self-defense" or anything like that; at the time immediately after it was written it was legal for a private citizen to own live cannon and other major military weapons with no permits or other regulation. While the regulation of small arms is controversial, I don't hear anyone arguing that people should be allowed to walk around with a sack of grenades or an anti-tank missile, or that billionaires should be free to buy their own nuclear weapons, though this would be in line with the strict wording of the 2nd amendment.

      Rather than go through the trouble of amending the constitution to remove this restriction, they simply "reinterpreted it". They found drafts with extra commas. They decided that the comment on justification (A well-regulated Militia being necessary to the security of a free State) eliminated all meaning. Now the only worry weapons-banners have is whether their laws will be popular.

      The Vietnam war? The civil war? The gulf war? All completely unconstitutional. The world wars were iffy, but there were certainly completely unconstitutional things done during them.

Better to argue over what should be done and what must not be set into law based on consequences, rather than argue over whether technically this or that law is not allowed by your interpretation of the constitution.

They don't involve a controlled chain reaction, and produce considerably less energy than the same amount of radioactive material consumed in a conventional reactor. They also operate at a fixed, slowly decaying power level. But they are simple, compact, robust, and long-lived. So they are good for long-duration spaceflights (like to Saturn). Think more like a super battery than a reactor.

    Just a wild-assed guess, but I would think that the energy density of gasoline would be much higher than the energy density of one of these sources. Certainly the peak power you could attain would be higher for gasoline+internal combustion engine.

    It's unclear if he actually got a breeder reactor working i.e. achieved criticality. A breeder reactor is critical, generates power, and creates fissile material from non-fissile material through neutron bombardment. Criticality means the reaction is self-sustaining and does not need an external neutron source. In any case, a "critical mass" is not an absolute; it depends on moderator efficiency, neutron reflector casings etc.

    What he did was build a neutron source - which is not too hard, any alpha emitter and beryllium will do - and irradiated thorium and uranium. That will certainly give you a huge amount of all kinds of alpha, beta and gamma radiation. Actually neutron bombardment will turn just about anything radioactive. (But radioactive things don't glow! A popular misconception probably based on the Cerenkov radiation in swimming pool type reactors which emit a beautiful blue light.)

    Thats why Foreign countries can't do it easily: because of lack of availability of materials.
    Which "foreign countries" did you have in mind? India (one country whose nuclear program I'm somewhat familiar with) has vast reserves of thorium and reasonable uranium deposits. BARC - Bhabha Atomic Research Center - has done a lot of work on thorium fast breeders, and I suspect India has large reserves of U-233.

He built a neutron source (that's what frightens me, just about anything will go to a radioactive isotope and since they're not charged, neutron absorption cross-sections are huge compared to charged particles) and got lots of radioactive isotopes starting with uranium, thorium, and everything else in the potting shed. There was no shielding, no control over exactly what got irradiated. That's the difference between expensive labs run by all those "greatest U.S. and import scientists" in expensive labs and a kid in a potting shed.

The proprietor, Gloria Genette, still recalls the day when she was called at home by a store employee who said that a polite young man was anxious to buy an old table clock with a tinted green dial but wondered if she'd come down in price."

    This doesn't make sense. Geiger counters are not very sensitive because they depend on the ability of an energetic particle or photon to ionize gas molecules. This takes a lot of energy.

    To detect the radiation on the street using a geiger counter, the radiation near where the source was stored would have to be so intense that the workers in the store would become sick.

    Read message #173 above, by Kierthos (Kierthos@aol.com):

    "And as I recall, the radioactive particles emitted by Uranium are alpha (okay, it's been a long time, so I'm guessing), which can be stopped by a stout pair of pants."

    That's true. Beta radiation (fast electrons) doesn't travel far either. Another kind of radiation emitted by radioactive substances is gamma rays. Gamma rays are photons more energetic than X-rays. Gamma rays can penetrate easily. However, consider that the article quote implies that the distance over which the radiation was detected was from inside the store to the street. I'm guessing that would be at least 6 meters, or 20 feet.

    Gamma radiation from a radioactive substance is omni-directional. The energy radiates the same way in all directions. As radiation spreads into a volume, its intensity is divided proportional to the square of the distance. This means that someone working in the store would be exposed to a far higher intensity of radiation than would be detectable in the street.

    Also, the amount of radium (radioactive material) in luminous clock dials was extremely small. Radium was, and is, extremely expensive, so there never would have been very much in one place. Radium-226, the most common isotope, decays to half its original intensity in 1600 years. So there would never have been a reason to include an extra sample of radium with a clock.

    There are other problems as well. For example, do you intend to power your car just with the energy generated from radioactive decay? If so, I hate to break it to you, but there's not a whole lot to use. It's doubtful that you could use that power to move a car, expecially the large one you would need.

    In fact, the only way you could do this would be if you converted an 18-wheeler with trailer. Put a true fission reactor in the trailer, complete with boilers and cooling system, and run wires from the trailer to the truck itself, where you would have a large electric motor. Sinmply converting an old jalopy as a "tinkering project" would not work. Not to mention, for this nuclear-powered 18-wheeler, you'd need a commercial driver's licence.

    Of course, the fact that you'd essentiall have a whole 18-wheeler trailer filled with radioactive metals and contaminated water means a couple things. First, you would have to have thick lead wall all over the thing - how a top speed of 30mph sound. The fact you'd have a huge amount of power is irrelevent - the other problems involved with moving that much mass at that much speed (brakes, transmission, etc) are formidable. And frankly, I wouldn't want you driving fast in this behemoth anyway.

    Remember what I said about your entire trailer being filled with radioactive-contaminated water? Let me ask you this: How often does your car radiator spring a leak? Not often, true, but it has happened to you, hasn't it? In a nuclear power plant, there are hundreds of people checking every valve and in constant control. Your reactor will have one controller - yourself -and you will be driving while trying to control the reactor.
