Carbon dating art forgery - who is hines ward dating 2016

On August 6, 1945, an atomic bomb was dropped on Hiroshima and three days later a second, more powerful bomb was dropped on Nagasaki.About 550 further explosions were carried out by the United States, Britain, the Soviet Union and France before most countries signed the Limited Test Ban Treaty in 1963. Dr Basner’s team argue that this activity released isotopes into the environment that do not occur naturally.

Also, how far did radioactive fallout from the bombs get, and does the concentration vary from location to location?Caesium-137 and strontium-90 do not occur naturally.They are examples of "rare earths": elements created only by nuclear fission.So something closer to the initial blast/fallout would have both the higher initial isotopes and a corresponding higher 'bi-product' elements. In theory using this they could even get pretty close on -when- it was forged.Proly not the exact year, but within a 5-10 year estimate.Old documents have been forged fairly convincingly using the same basic method: Bleach a piece of old paper (to remove whatever was on it before), then make some ink by burning some paper the same age, and do your writing. A paint created before the testing wouldn't be effected and you can't use synthetic oils as they wouldn't have been produced in the periods an artist would be mimicking.

The use of accelerator mass spectrometry (AMS) for age determinations of paintings is growing due to decreasing sample size requirements.

This news is about a month old, but it's new to me!

Russian curator Elena Basner thinks she might have developed a foolproof way of determining whether a work of art was made before or after 1945. From the Times Online: The first nuclear bomb was successfully tested in July 1945 in New Mexico.

In fact, there's evidence that slight increase actually decreases you risk of cancer!

If you're still nervous, check out this site: even if the forgeries were closer or even in Japan at the time of The Bomb, this method would still work. Compare the isotopes currently detected vs their decay products. Heck, Caesium-137 has a half-life a little over 30 years, and Strontium-90 about 29 years.

Because brain cells aren't replaced like other body cells, they retain the carbon 14 that was produced in elevated levels at the time. )I feel that I should allay fears that my above post might cause.
