Synopsis: Chemistry & chemical compounds: Chemical compounds: Isotope:

what the animal was eating by adding data from stable carbon isotopes. Potential uses Samuel Wasser a conservation biologist at the University of Washington who did not participate in the study said the new study is a very important development

By looking at the levels of this carbon isotope known as carbon-14 in elephant tusks and ivory researchers can find out how old they are.

Isotopes are versions of elements that have differing numbers of neutrons in their nuclei. Knowing the age of elephant tusks is important

By contrast coal-fired power plants release higher quantities of radioactive isotopes directly into the atmosphere than even the oldest nuclear reactors ever did.

and the nuke plants that create those isotopes or the ones that were built specifically for safer power generation

Carbon's key radioactive isotope carbon-14 forms when energetic particles enter Earth's atmosphere

So the formation of radioactive isotopes isn't a steady process? This could cause us to change our assumptions about dating methods.

tree ring studies and sedimentary cores can often be used to identify variations in the atmospheric concentrations of whichever isotope is being used

They were measuring the relative change in the isotope from one year to the next. As a side note that may interest@Bagpipes100:

and food products companies to apply the sensors to measuring the isotopes in foods. The intention:

Iain Green, vice president of business development for Picarro, said every food gives off a unique isotope signature.

Freitas points out that the isotope gadolinium-148 could provide much of the fuel the body needs.
