Antimatter Hazard Symbol pops up!

A red-letter day!  The Antimatter Hazard Symbol I proposed nearly two years ago has found its first physical application!

…Well, pseudo-physical, anyway.

While the symbol, (which is based on internationally-accepted color coding in combination with Title 10 of the U.S. Code of Federal Regulations, Part 835, Subpart G posting guidelines,) has found its way into online articles here-and-there, it hadn’t found it’s way onto something more substantial until now.

Benjamin Swem, a Second Life user also known as Krahazik Zaytsev, recently asked my permission to use the symbol.  His application?  In true, classical science-fiction fashion, it was to be affixed to an antimatter containment pod powering a fictitious spacecraft he was in the process of creating to sell in-world.

I’m must say I’m quite pleased with the result.

The symbol, for those who hadn’t seen my original proposal, is a modification of the familiar radiation “trefoil,” replacing the “caution” yellow-and-black coloring with the more threatening “danger” red-and-black.  Each of the radiation “foils” has been bisected to impart the concept of additional energy, the foils themselves have been inverted to further distinguish it from a “ordinary” radiation trefoil, and the center of the symbol is two inverted circles overlapping (instead of one circle) to represent the interaction of matter with antimatter. 

Instantly familiar, intuitive, yet more ominous is what I was after.  (A symbol doesn’t do anyone any good if no one recognizes it, so why not leverage existing symbology as an advantage?)

  • *For the scientifically-inclined, the radiation symbol is also very technically-accurate one.  Considering the actual threats posed by antimatter, a primary danger of proximity to annihilating antimatter (even in storage systems!) is from gamma-rays emitted as particles and anti-particles collide.  For electrons and positrons, this energy is a gamma-ray with peak energy observed at 511 keV, which can penetrate even very thick shielding.  (We actually use the annihilation of naturally-occuring positrons to help calibrate our instruments, so make no mistake, antimatter exists! – Just naturally in small enough quantities that it doesn’t really cause any negative effects.)

Admittedly, it’s a bit early to be terribly concerned with protecting the public from incidental encounters with antimatter – but thinking about it ahead-of-time can’t hurt.

And in fact, with the relatively-recent discovery of natural sources of antimatter, we may develop the ability to amass stores of the material sooner than we imagined.

So, feel free to use the hazard symbol as you wish; All I ask is that you just let me know how you intend to use it and send me a link or image of the result!

Antimatter Hazard Symbol finds early adopters!

Those who have been long-time readers will remember a proposition I made for an antimatter hazard symbol (otherwise and less formally called a “warning sign”) back in May of 2010, which was based on currently-accepted international hazard symbology and color schemes. 

Well, to date, I am excited to report that the symbol has found some early adopters across the cyberverse.  Foremost amongst these is the website, WeInterrupt.com, who made a stab at a somewhat technical, somewhat tongue-in-cheek article featuring the symbol last June.

Much earlier, (a year ago last November,) the site “ParanoidNEWS.org” incorporated the symbol into a fairly fantastic, paranoid montage with a nuclear mushroom cloud (at right) cresting a somewhat crass article about the potential development of antimatter weaponry. 

Patently alarmist, and the color scheme was artistically distorted, but still a cool image.

Finally, in August, a blog called “AngelsDoSpeak” included the symbol in a breakdown of potential nuclear fallout or activity symbols.  (The purpose of the symbol’s inclusion here on a religious site was a little confusing or perhaps ominous, but I’m happy with adopters all the same.)

While I should note that there have been other internet-promoted proposals for an antimatter hazard symbol, I feel quite strongly (based on my current work in the radiological protection industry) that instead of attempting to promote a new glyph or design into the hazard iconograhy pantheon, any antimatter symbol should derive from internationally-recognized symbology already in place.  This symbol should then simply be evolved/modified to capture antimatter’s potential hazard as a highly-reactive source of radiative energy, which I believe the above symbol does quite nicely.

-And while this effort is admittedly precautionary, the recent discovery that the Earth’s magnetic field traps naturally-ocurring antiprotons into a belt (a la the Van Allen Radiation Belts) may make orbital harvesting of antimatter a plausible pursuit.

In any case, feel free to promote the hazard symbol or use in your own projects or research if you so desire, and as always, comments are welcome.
