Among the significant events that caused a temporary but significant spike in the atmospheric carbon-14 to carbon-12 ratio were above-ground nuclear test detonations in the two decades following World War II.
is a term for radiocarbon dating based on timestamps left by above-ground nuclear explosions, and it is especially useful for putting an absolute age on organisms that lived through those events.
The Committee also may consider indicators that do not cover the entire economy, such as real sales and the Federal Reserve's index of industrial production (IP).
The Committee's use of these indicators in conjunction with the broad measures recognizes the issue of double-counting of sectors included in both those indicators and the broad measures.
(a) Definitions in this chapter apply to this title.(b) If, in another part of this title, a term defined by this chapter has a meaning different from the meaning provided by this chapter, the meaning of that other provision prevails.(c) Except as provided by this chapter, the definitions in Chapter 101 apply to terms used in this title.
"Court" means the district court, court of domestic relations, juvenile court having the jurisdiction of a district court, statutory county court, constitutional county court, or other court expressly given jurisdiction under this title.
The unstable carbon-14 gradually decays to carbon-12 at a steady rate. Scientists measure the ratio of carbon isotopes to be able to estimate how far back in time a biological sample was active or alive.Organisms at the base of the food chain that photosynthesize – for example, plants and algae – use the carbon in Earth’s atmosphere.They have the same ratio of carbon-14 to carbon-12 as the atmosphere, and this same ratio is then carried up the food chain all the way to apex predators, like sharks. "Prosecuting attorney" means the attorney, determined as provided in this title, who represents the state in a district or statutory county court in the county in which venue of the application for a protective order is proper. is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past. To understand radiocarbon dating, you first have to understand the word Although an element’s number of protons cannot change, the number of neutrons can vary slightly in each atom. The chronology comprises alternating dates of peaks and troughs in economic activity.
