Atomic dating using isotopes
The particles given off during the decay process are part of a profound fundamental change in the nucleus.
To compensate for the loss of mass (and energy), the radioactive atom undergoes internal transformation and in most cases simply becomes an atom of a different chemical element.
The mass spectrometer is able to give information about the type and amount of isotopes found in the rock.
Scientists find the ratio of parent isotope to daughter isotope.
Some wine experts estimate that up to 5 percent of the fine wine sold today is fake.
Because isotopes differ in mass, their relative abundance can be determined if the masses are separated in a mass spectrometer (see below , which permits the identification of daughter atoms formed by the decay process in a sample containing radioactive parent atoms.
As the isotopes decay, they give off particles from their nucleus and become a different isotope.
The parent isotope is the original unstable isotope, and daughter isotopes are the stable product of the decay. In the first 5,730 years, the organism will lose half of its C-14 isotopes.
“Connoisseurs collect vintage wines and prices have soared with ‘investment wines’ selling for hundreds of thousands of dollars a case at auction.” Jones said the wine industry is fighting forgeries with special seals and high-tech labels.
The method for authentication of a wine’s vintage may provide added confidence that the vintage on the label is the vintage in the bottle.
