After a certain number of half-lives elapses, the remaining amount of carbon-14 is too low to measure with precision. Also, the risk of contamination becomes much greater; i.e., a small contamination will have a larger effect.
Carbon 14 is the isotope that is used for carbon dating.
Nothing. Something must contain carbon to be carbon dated. By definition fossils are mineralized and contain no carbon.
Either non-carbon dating, if that's what you mean, or nothing. But technically, there is no real antonym of "carbon dating".
It involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content. Carbon-14, or radiocarbon, is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.
Carbon 14 is the isotope of carbon measured in radiocarbon dating.
The carbon footprint is measured in the amount of carbon dioxide (CO2) that has been emitted over the full life cycle of a product or service.
carbon dioxide gas
Yes.
The ratio of carbon-14 (radioactive) to carbon-12 (nonradioactive) is measured.
Indirectly yes. It causes global warming, which increases carbon dioxide in the atmosphere.
Promoting a shift from the use of fossil fuels to sustainable energies can help to balance the carbon cycle.
The beta radiation of the isotope carbon-14 is measured.
forests absorb the carbon dioxide and help to maintain balance
Carbon dioxide has a measured magnetic susceptibility.
Carbon 14 is the isotope of carbon measured in radiocarbon dating.
It is normally measured with a carbon monoxide detector meter, concentration given in parts per million
