[VIDEO] How Nuclear Weapons Screwed Art Forgers


How Historians Are Using Nuclear Fallout to Find Fake Art

Andrew Tarantola writes:

…Since the start of the 1960s, the art world—especially the modern art world—has been besieged by a torrent of faked “masterpieces.” Peggy Guggenheim (yes, thatGuggenheim) was once famously duped into purchasing what was believed to be a canvas painting by French artist Fernand Léger completed around 1913. It hung in her private collection for decades before being revealed as a forgery. This problem only expanded through the 1980s and 1990s as the market for modern art exploded.


“The number of avant-garde fakes out there today is unbelievable, probably more than the number of genuine works,” says Dr Elena Basner, an art historian and curator of 20th-century art at the State Russian Museum in St Petersburg who is now a consultant to the Swedish auction house, Bukowskis. “I noticed that forgers already had all the angles covered, and could perfectly reproduce the paints, canvas, etc., so I wanted to find something ironclad in these paintings that couldn’t be disputed, and this led me to approach scientists for ideas.”

The Bomb Peak: Nuclear Fallout’s Silver Lining 

The world’s nuclear nations exploded 550 nuclear weapons during tests between the years of 1945 and 1963 when the Limited Test Ban Treaty outlawed all above-ground detonations. 552 if you count Hiroshima and Nagasaki as well. One of the unintended side effects of these tests was the release of two fully-artificial isotopes that only form during a nuclear bomb blast: caesium-137 and strontium-90. These isotopes were absorbed by the soil and incorporated into the cellular structure of plants. In fact, they were absorbed by just about everything—soil, plants, animals, people—everybody alive in between 1945 and 1963 has elevated levels of these isotopes compared everything that lived before that time. This is trend is known as the “Bomb Peak.”


Since the implementation of the Limited Test Ban Treaty, the environmental prevalence of these isotopes are falling back to pre-atomic age levels, though with a half life of roughly 29 years for both isotopes, they’re going to remain in the soil for centuries to come. So when, say, a flax plant growing in contaminated soil is processed into linseed oil (a common pigment binding agent), those isotopes remain. This provide scientists with an easily identifiable timestamp—if there’s caesium-137 and strontium-90 present, the work of art clearly could not be before 1945. Now that doesn’t mean that if the isotopes aren’t present it simply isn’t an old forgery, just that it was produced before the start of nuclear tests.

Basner’s test, which she developed with freelance chemist and Russian avant-garde art lover, Andrey Krusanov, only requires a miniscule sample of canvas taken from the edge of the frame to be run through a mass spectrometer.

“Flax in the fields absorbs these two isotopes from nuclear fallout, and the binding agent in paint production is based on natural oils, such as linseed from the flax,” Krusanov explained. … (read more)
