Radioactive Wild Boars Found in Northern Italy

The Italian newspaper Corriere Della Sera reports that traces of cesium-137 contamination have been found in dozens of wild boars taken by hunters in the northern Valsesia [Sesia Valley] forests, in the province of Vercelli.
[27 A]nalyzed samples of [the] tongue and diaphragm of animals slaughtered during the hunting season 2012/2013 [showed] level[s] of Cesium-137 higher than the threshold specified by Regulation 733 of 2008 as the tolerable limit in the event of a nuclear accident. According to the deputy of the Piedmont Region, Roberto Ravello, alarmism should be avoided because the health risks would be "contained and controlled."
According to Elena Fantuzzi, head of the Institute of Radiation Protection ENEA, the most immediate explanation is that the contamination originated from the 1986 Chernobyl accident. However, she cautions, (translation via GoogleTranslate) "[W]e must also consider the nuclear sites in the area, including the central Trino Vercellese ["Enrico Fermi" nuclear plant] dismantled in 1987 and the experimental site Enea, in Saluggia...[We can not exclude] the trail of toxic waste." Gian Piero Godio, a nuclear expert in the Legambiente Piemonte and Val d'Aosta region adds, "[There may be o]ther explanations....the district of Valsesia has no radioactive source[s]."

Argonne National Laboratory Energy Showcase: Photo Slideshow

As promised, Part Two of our coverage of the Saturday, September 15th Argonne Energy Showcase open house event. Our video highlights can be seen in the first installment of our Energy Showcase posts. Here's our full Flickr slideshow of over 50 photos with captions. Top: "Now, That's Cold!" Argonne researcher explains the technology behind the ATLAS (Argonne Tandem Linac Accelerator System) facility, the world's first superconducting linear accelerator for heavy ions. The object on the table is a model section of ATLAS' "superconducting split-ring resonator."

Center: "Hot or Not?" This very popular FLIR imaging exhibit in the Nuclear Energy building allowed visitors to see live video of themselves in the room with color-coded temperature gradients. As you can see, some people are literally hotter than others. A similar station set up in the Advanced Photon Source (401) complex let visitors take home a snapshot printout of their FLIR scans.

For even more images, visit Argonne National Lab's official Flickr photostream.
Bottom: "Clean and Green" One of the several advanced hybrid electric vehicles in the Sustainable Energy Tent. Some of the other new technologies on display were demonstrations of biofuel generation using fermented waste, vehicle charging stations, and an area where visitors could ride the "Energy Bike" to see how much pedaling they have to do to light up a conventional incandescent light bulb, versus the effort needed to make LED and compact fluorescent devices glow. As we can vouch, it takes a lot less legwork to make those clean and green LED's shine!

Video Highlights from Argonne National Lab's Energy Showcase 2012

Didn't get a chance to visit Argonne National Laboratory's 2012 Energy Showcase in the Chicago suburbs this past September 15th? Don't worry: we're very happy to share our video and photo highlights from this rare opportunity to peek inside the birthplace of modern nuclear science, and see first-hand some of the amazing research being done in America's heartland.

According to an on-site event organizer, this year's open house was the first one held in five years, after tighter security restrictions post-9/11 put National Laboratory open houses on hold. This year's Energy Showcase was also the first to require visitors to pre-register online. While past events had as many as 20,000 visitors each, Energy Showcase 2012 hosted a more modest registered attendance of approximately 2,000* - not necessarily a downside if you were seeking a good, close look at the dozens of fascinating exhibits on hand. [*According to another person I spoke to later, the registration attendance was capped at 10,000, so I may have misheard the original attendance estimate. If any readers out there have more solid attendance stats, please let us know in the comments! - LR]

First, let's stop in at the Physics building to have a look at the Gammasphere, the world's most powerful spectrometer for nuclear structure research. If the Gammasphere looks familiar, you may remember that the device had a 'guest starring role' in the 2003 feature film "Hulk," as the contraption that triggered Bruce Banner's verdant transformation - back then, it was physically located at Lawrence Berkeley National Laboratory. Read more at http://www.phy.anl.gov/gammasphere/index.html



Next, let's take a short drive south to the nearby Advanced Photon Source complex, a facility which provides the brightest x-ray beams in the Western Hemisphere to more than 5,000 scientists from around the United States and the world. Here's a panned view from the APS observation gallery, as a researcher gives a basic explanation of its workings in the final 30 seconds or so of the video. In person, the building and equipment are remarkably large; what you see here on the video is only a tiny fraction of the APS accelerator "ring." More at http://aps.anl.gov/About/APS_Overview/



Here is a live demonstration of a technique called "acoustic levitation" that uses high-frequency (~22kHz) sound waves to suspend small objects like liquid droplets, plastic spheres, and popcorn in mid-air. Bystanders could manipulate and rearrange the plastic beads within the sound column using a metal spoon, creating intriguing patterns. As you can see from the video, the column behaves as though the beads are 'magnetically' attracted along an invisible vertical line running between the upper and lower sound generators. The demonstrators explain that the beads are spaced at wavelength node intervals of about one-third inch, allowing visualization of the standing wave. More at http://www.anl.gov/articles/no-magic-show-real-world-levitation-inspire-better-pharmaceuticals



Down the hall, we stopped by to see an X-ray diffraction demonstration, which provides a simulation of how the APS' powerful X-ray beam can reveal the before-unseen inner structures of nanoparticles, proteins, crystalline structures, organic molecules, and many other materials.

In part 2 of our look inside Argonne National Laboratory, we'll visit ANL's Nuclear Museum, home of many historical treasures from the dawn of the Atomic Age.

Surfing the Nuclear Web: from Australia to Argonne

Looking for more radiation related sites? There's the informative and descriptively-named Radioactive Waste blog from Australia:
Being an environmental scientist of the disorganised type, and also overwhelmed by the quantity of sites of relevance to my interest in safety of radioactive waste, my hope is that this blog will bring some order to my life (this part at least)! All views & irreverent commentary expressed here are entirely my personal opinion, of course. In Australia, after cleaning up the mess at Maralinga (former UK nuclear weapons test site), we are now in process of building a national radwaste repository.
Jef's Web Files has a section focusing on nuclear safety, with recent posts about the development of detectors that can "smell" nukes, and the U.S. government's recent revival of a lost Cold War art - fallout analysis.

Atom Central is an intriguing portal with sections on the atom bomb, the Trinity site and video releases on Hiroshima and Nagasaki, American bomb tests and more.

Of special interest is the Argonne National Laboratory's engineering research website:
Argonne's rich heritage in the development of nuclear reactors began with CP-1, the world's first nuclear reactor brought to life by Enrico Fermi and his team on December 2, 1942, under the West stands at Stagg Field on the campus of the University of Chicago.

Dr. Walter H. Zinn, one of Fermi's close colleagues working on CP-1, became Argonne National Laboratory's first director in July 1946. In 1948, the United States Atomic Energy Commission (AEC) transferred the major portion of the nation's nuclear reactor development program to Argonne. Under Dr. Zinn's vision and leadership, Argonne established a vigorous and far-reaching program to develop nuclear reactors of virtually all types.
You can see some of Argonne's history in video: Argonne's pioneering nuclear research is prominently featured in the documentary Atoms for Peace (1994, VHS), hosted by Bill Kurtis (whom we met as the host of the program NOVA: Back to Chernobyl). This one-hour feature details the history of the American peacetime nuclear program with its focus on energy production (and the U.S. fast-breeder reactor program, now on indefinite hiatus), as well as its linkage back to the early weapons development initiatives at Oak Ridge National Laboratory in Tennessee, Arco, Idaho (the first town to be powered by nuclear energy) and the now-defunct Hanford site power plant in Washington state. While Atoms for Peace is a bit hard to track down, you'll probably be able to find a copy at larger public libraries with video collections.
