A quick definition of NAA:
Term: NAA
Definition: NAA stands for Neutron-Activation Analysis. It is a scientific method used to identify and measure the amount of different elements in a sample. This is done by exposing the sample to neutrons, which causes the elements to become radioactive. By measuring the radiation emitted by the sample, scientists can determine the types and amounts of elements present. NAA is used in many fields, including archaeology, environmental science, and forensic science.
A more thorough explanation:
Term: NAA
Definition: NAA stands for Neutron-Activation Analysis.
Neutron-Activation Analysis is a scientific technique used to determine the chemical composition of a substance. It involves bombarding a sample with neutrons, which causes the atoms in the sample to become radioactive. By measuring the radiation emitted by the sample, scientists can determine the types and amounts of elements present in the sample.
For example, NAA can be used to analyze the composition of archaeological artifacts, such as pottery or metal objects. By analyzing the chemical composition of these artifacts, scientists can learn more about the culture and technology of the people who made them.
