Atlas Experiment at CERN

At the CERN facility in Geneva, Switzerland, a mammoth detector array is being built to detect events resulting from proton-proton collisions.  It is called Atlas.  There is an impressive collection of public outreach web sites to afford some background to the interested viewer.  The Atlas project has produced some swell animation too. 

I think these physicists have done a first-rate job of trying to make their work comprehensible to the public.  I wonder if we chemists have made a comparable effort in our endeavors? But maybe there are not comparable projects in chemistry.  Whereas there are 1800 physicists working on Atlas, where are there comparable numbers working in unison in chemistry?  Answered my own question.

Isotope Mojo Blues

Near as I can tell, there is some kind of demand in the marketplace for all of the elements from 1 through 92, with the exceptions of Pm, At, and Rn, I suppose. It is hard to gauge the trade in actinides since precious little gets outside the realm of government regulatory frameworks. Clearly there is demand for certain isotopes of Th, U, and Pu.  But the nuclear regulatory people keep a tight reign on that stuff.

I remember a pottery class I took some years back in a nearby town. I was snooping through the pottery stockroom looking for glazes and what did I find? I found a sizeable quantity of Thorium nitrate.  These hapless middle-aged, post-hippy era, meadow muffin starving artisans running the co-op clearly had no idea that they had an actinide a nuclear-age artifact in their midst. Obviously, it had been secured for colored glaze applications.  I warned them about it but was met with the cow-in-the-headlights-look. I call it the “bovine stare”.  So, I brought a GM survey meter the next week and opened up the jar with a few of them standing there. As the clicks ramped up from the beta’s and as I switched the attenuation to keep the needle on scale, I thought I heard the unmistakeable faint slapping sound of multiple sphincters slamming shut.

The first question was “Would I like to have it?”.  Pppffffttttt!  “Hell no!” says I.  Nuclear cooties. Jesus H. Crimony!!  I did a careful survey with the GM counter and found that the surrounding area was clean. The material (early 1960’s vintage by the looks of the label) had hardly been used, so I was confident that contamination was not too bad, if indeed there was any. There may have been alpha emitters but this counter wouldn’t pick them up.  I gave some names of hazardous waste vendors and a stern warning not to drop it or spill it.  That’s the last I heard of it.

I remember a seminar in grad school when a visiting rock star from ETH gave an organic seminar detailing the use of Li-6 in NMR studies.  The fellow lamented in his fastidious German/Swiss accent that it was difficult to get Li-6.  He also said that for a time much of the refined Lithium in the market place was depleted of Li-6.  It would be interesting to hear someone comment on the accuracy of this. 

Active Denial System- RF Radiation Weapons

It appears that some of our clever friends and neighbors at the local military/industrial complex have been busy designing millimeter-wave radio frequency weapons.  Last year the DoD announced the development of a new form of weapon billed as non-lethal to fill the “gap between shoot and shout”.  The device consists of a powerful rf source and what must be a fairly narrow beamwidth antenna for illuminating unruly people.  The website includes video clips of test subjects and their descriptions of what it feels like to be on the receiving end of this radiation weapon. 

I refer to it as a radiation weapon because that is precisely what it is.  Millimeter wave radiation is directed at a person or a crowd and in short order the recipients in the beam feel their skin temperature rise to discomfort. Whether it truly raises skin temperature or the sensation is an artifact of surface electrical currents in the skin is unclear. The fact is that it can cause instantaneous discomfort and anxiety about burning to a crisp.  Obviously, the purpose is to discourage aggressive behaviour in individuals or of crowds and do so in a non-lethal manner. 

So, really, what is wrong with this?  In a sense it is like a shock collar on a dog.  An occasional burst of juice causes the unruly dog to suspend the offensive behaviour.  The dog learns the lesson and is not physically harmed by it. 

I’ll admit to being quite uncomfortable with this “technology”.  The potential for abuse and exploitation is staggering.  If a short burst of rf energy will cause people to scatter or desist their behaviours, what will a long exposure do?  And, just what happens to someone on prolonged exposure?

What is the difference between negative reinforcement and torture?  Is it the difference between a 5 second exposure and 60 seconds?  And, when will a tin-pot dictator acquire this capability now that we have proudly trotted ours out?  Whereas ours will have controls for non-lethal operation, would a terror group or arms merchant bother to have safety protocols to guard against overexposure? Maybe a stripped down version absent interlocks will be the weapon of choice among African dictatorships.

How long will it take for civilian units to come on stream? What US city will be the first to acquire one of these things for crowd control and when?  LA?  DC?  NYC?? 2015? 2020?  Pretty soon every SWAT commander will be clamoring for one “just in case”.  Whose march on the Capital Mall in DC will trigger the first use of such a device on civilians? 

Can the energy be reflected back to the source or in some other direction?  Is a metal trash can lid or aluminized mylar blanket an effective countermeasure?  Maybe we’ll see rock throwing 12 year olds in Gaza with a stone in one hand and a trash can lid in the other after its inevitable introduction in the middle east.

Microwave/millimeter technology is ubiquitous.  No nuclear materials. No ammunition.  Just a powerful rf source and an antenna. No doubt arms merchants are already lining up buyers for this weapon of mass agony.

What a lamentable development for mankind.  Our ability and willingness to commit violence from a distance is one of our greatest downfalls.

Better Gadgets

The National Nuclear Security Administration (NNSA) announced on 3-2-07 that the US would be pursuing the Reliable Replacement Warhead (RRW) program.  The program makes a lot of sense on many levels. But the timing of the press release is a bit odd.  Certain sandy states will no doubt notice the irony of the program. While the US is browbeating them into abandoning their dreams of a fissile future, we on the other hand are pursuing better and safer nukes.  Of course, we’ll argue that it is a smaller and safer stockpile, and I’m sure that is true. But I’ll wager that the next generation nuke will be designed for better efficiency as well. 

Maybe we’ll launch them from the new Cheney Class of submersible aircraft carriers…

Some Sunny Day

This link shows the closing scene of Dr. Strangelove.  Why are atomic bomb blasts so fascinating to watch? Of course, the movie was a satire.

But when you see the next one, it becomes much more sobering.  It is a clip from a BBC documentary with CGI enhancement on Hiroshima. Part of the responsibility of having civilian control over military forces in the USA entails that at least some fraction of the civilian population retain a bit of knowledge of topics like this.

I think that when queried, most people will think of an atomic bomb blast as primarily a nuclear radiation calamity. To be sure, there is a healthy gamma pulse and the dispersal of a large variety of troublesome radionuclides, with long lasting contamination issues.  But much of the prompt destructive effect is from the immense heat pulse followed by the blast wave. 

Mutual assured destruction (MAD) as a nuclear strategy was arguably successful because parties on both the NATO and Soviet blocks were more desirous of long life than of the need for the delivery of nuclear hellfire at any cost.  The cold war was a time of opposing political and economic doctrines. MAD was essentially a secular concept.

In the present era of religious theatre, movements citing supernatural endorsement of earthly doctrines are in ascendancy.  The calculus of MAD fails when parties practice nuclear policy under the influence of supernatural euphoria.

Atomic Bob and his Gravity A-Waves

Imagine my surprise when I look a little deeper into United Nuclear and find that its founder is none other than Bob Lazar.  In the previous post I mildly endorsed United Nuclear as a supplier of low level radioactive sources for experimentation. They appear to be a legitimate supplier of safe to handle sources. I haven’t changed my mind about the need for such suppliers but I am cautious about their grasp of physics.

It turns out that Bob Lazar has quite a reputation in certain circles concerned with extraterrestrial visitors. Lazar does get quite a bit of airplay.  Just this morning while in a groggy half sleep I heard Lazar interviewed on a UFO program on the Travel Channel.

It turns out that Bob Lazar claims to be a nuclear physicist and claims to have been involved in work aimed at understanding the flight mechanisms of a flying saucer disc in storage at Groom Lake, Nevada, in what is called Area 51

In a secret underground laboratory Lazar and others discovered the secret to the flying disc’s power source. Element 115 is transmuted to Element 116 by proton absorption, followed by the emission of two antiprotons. These anti-protons form a flux that travels down a tube whereupon they undergo annhilation with gasses found there. A great amount of thermal energy is liberated which is then converted to electric energy. But wait, this isn’t even the fun part.

The reaction of element 115, Ununpentium, also evolves a type of gravity wave that follows the curved shape of the flying saucer disc, which Lazar refers to as a “tuned wave guide”. This gravity wave propels the flying saucer disc through space-time by warping space.

Golly, that explains a lot. It always struck me that the saucer shape with it’s high surface to volume ratio must have put a real crimp on luggage space for the aliens. Also, what are the aerodynamics of a saucer shape? Man, this kind of stuff is perfect for the unedited internet.

So, I’ve driven my Jeep off the road into this Lazar swamp and now it is time to get back on the road.

This Lazar guy is pretty creative. But perhaps he should’ve taken a cue from Joseph Smith and started a religion instead. Lazars craziness physics is falsifiable if you wanted to go to the trouble. But religion uses the supernatural interface which is not falsifiable with physics. So, a religious wild-assed scheme is far more durable than one based on natural phenomena.

Vlad the Irradiator

The curious tale of murder by radiolysis becomes more convoluted each day. A Google search reveals an expanding table of accusations and denials, each party having some kind of axe to grind. There are the British authorities, anti-Putin exiles, Russian oligarchs, a diminishing group of fearless Russian journalists, angry and indignant ex-Soviet KGB patriots, and of course, Tsar Putin.  This case is beginning to reveal that there may be no perfectly clean parties, radiologically or otherwise. 

This is a fleeting glimse of a struggle takig place between bitter Russian ex-patriots and the Putin regime.  Some sketchy reports indicate that this disturbing battle involves an underworld of operatives working for both oligarch wise-guys and organs of the state secret police. It’s just creepy. There is no other way to put it.

But, it could easily be that the murder of Litvinenko was pulled off without the knowledge or sanction of the official security apparatus and was executed by freelancing bad guys.

Switching subjects now, a company in New Mexico called United Nuclear has an interesting commentary on it’s website, though I’m not sure that it makes any actual conclusions.  But, you can get a Polonium-210 coffee mug.  A 0.1 microCurie Po-210 source will run ya about $69.00. United Nuclear claims that their sources couldn’t have been used in the Litvinenko killing.  Assuming that their comments are accurate, I would have to agree with that conclusion.

I hasten to add that it is important that there be a commercial source of such things.  In order for people to invent new products using radiation, we need suppliers like United Nuclear.  We also need radiation sources for teachers to educate students and the public about radiation.  These people have some pretty cool stuff and it is my sincerest wish that pointy headed fools in DC do not try to clamp lots of extra constraints on to companies like United Nuclear because of the Litvinenko murder.  Gosh, it’s a good thing that Po-210 wasn’t found in somebody’s shoe. The TSA would be making us scan our feet at the airport.

The Coming Nuclear Caliphate

So, here we go. You know the nauseating feeling and that metallic tang sensation you get on your tongue when you’ve narrowly averted a car crash or had some other close call? Well, a recent news article has left me with the same feeling.  

According to an article in the Jerusalem Post, a group of middle eastern countries have signalled to the IAEA that they are interested in establishing a “common program in the area for nuclear energy for peaceful purposes”. 

The subtext of the Israeli article is that this move is a kind of equilibration by Sunni populations in response to Iranian/Persian Shi’ite nuclear development.  The countries in question are Egypt, Morocco, Algeria, Saudi Arabia, Tunesia, and the United Arab Emirates. 

According to the IAEA, 29 nuclear reactors are under construction in the world today.  Seven of them are in India, which plans to increase their number 8-fold by 2022. China has four reactors under construction and reportedly plans a 5-fold expansion in the next 15 years.  The IAEA keeps a handy list of new and retired reactors around the world.

Here is a nuclear joke you can tell to entertain your friends! Question: How many nuclear engineers does it take to replace a lightbulb? Answer: Fifty! One to replace the bulb and forty nine to figure what to do with the old one! 

On the one hand, it is logically and morally precarious to deny others what you yourself have enjoyed since the end of WWII. That would be the reassuring hum of nuclear electricity and prospect of security through the overwhelming firepower afforded by fission. 

On the other hand, the existing nuclear states have built infrastructure for the safe movement of nuclear materials through the system and folding new states into it may not be so hard.  However, the existing nuclear states have a compelling interest in avoiding disruption of the nuclear fuel cycle. More demand means higher prices.  Maybe the existing nuclear states should form something like OPEC to regulate the supply of nuclear fuel? 

I’ll admit that I’m a bit nervous about the prospect of Middle Eastern states becoming handy in the nuclear arts.  Any given “Atoms for Peace” program could degrade into a shell game that could hide a nuclear weapons effort. 

A plain reading of history seems to show that if someone else is helping with some of the enrichment, straight fission bombs are not as hard to develop as one might have supposed. It’s hard if you start ab initio with a pitchblende mine, a cloud chamber,  and F=ma.  But if you can outsource reactors and fuel, it’s a lot easier. The art in bomb design appears to be wringing out the biggest bang for the smallest amount of fissile material. Fortunately for everyone, thermonuclear bombs seem to be substantially trickier to make- my conclusion based on the open literature. 

If you think about it, a pre-nuclear state will almost certainly conclude that not having a nuclear weapon is tantamount to suicide. So the pressure to build nuclear weapons is irresistable to many regimes.

A nuclear arms buildup among the theocratic states seems especially worrisome, even though secular states like the USSR and North Korea make a poor case for secular stewardship.  Like it or not, the notion of MAD- Mutual Assured Distruction- did provide balance in the cold war between NATO and the Warsaw Pact.  Maybe what we are seeing is a nascent MAD in the middle east.

The worst case would be where the much desired Islamic Caliphate would have a “nuclear option”.  We can only hope that islamic theocratic fever is quenched by the pragmatics of economic prosperity. This is where a levelheaded US government could lead the way.

He leadeth me to walk beside the radiant pastures …

Chins are wagging over the what is being called a slip-up by Israeli Prime Minister Ehud Olmert.  According to the New York Times, during an interview with a German cable news channel, Olmert reportedly said

“Iran openly, explicitly and publicly threatens to wipe Israel off the map. Can you say that this is the same level, when they are aspiring to have nuclear weapons as America, France, Israel, Russia?” [Italics by Th’ Gaussling]

Oops! How do you say “Faux pas” in Hebrew? 

It’s kind of silly that this is even an issue.  For quite some time the only real questions have been- 1) How many coats of Turtle Wax are on the bomb casings? And, 2) Did they buy the extended warranty?

It’s an open question as to whether or not speaking publicly about its nukes enhances their deterrent effect for Israel. Look at that fetid Stalinist shrimp, Kim Jung Il.  He waves his nuclear capability around like a brain damaged test monkey with a turd on a stick. And, of course, we afford him the courtesies alloted to a brain damaged test monkey. A’hem.
