The major advantage of neutron activation analysis is that it provides a nondestructive method for identifying and quantitating trace elements.

Question

Quizplus · Accepted Answer

Neutron activation analysis (NAA) is a nondestructive analytical technique used to determine the concentrations of elements in a vast array of materials. It involves irradiating a sample with neutrons, causing the elements present to form radioactive isotopes. By measuring the gamma rays emitted by these isotopes, it is possible to identify and quantify the elements without altering the physical or chemical state of the sample.
