A quick definition of neutron-activation analysis:
Neutron-activation analysis is a way to figure out what something is made of by shooting it with tiny particles called neutrons. When the neutrons hit the material, it gives off a special kind of light called gamma rays. Scientists can measure these gamma rays to learn about the material. This method can be used to find out if someone has recently fired a gun by looking for tiny bits of gunpowder on their hands. It can be expensive, but it is often allowed as evidence in court.
A more thorough explanation:
Neutron-activation analysis is a scientific method used to identify and analyze physical evidence. It involves bombarding a sample of material with neutrons in a nuclear reactor and then measuring the gamma rays emitted by the sample. This technique can be used to detect the presence of certain elements or compounds in a sample.
For example, neutron-activation analysis can be used to detect gunshot residue on the hand of someone who recently fired a gun. The technique can also be used to analyze archaeological artifacts, geological samples, and environmental samples.
Neutron-activation analysis is an expensive technique, but it is often allowed as evidence in court cases because of its accuracy and reliability.
