n: a reaction in which an element has been changed into an unstable isotope during bombardment by neutrons.

near formation area is irradiated with neutrons that transform some nuclei into isotopes. The isotopes produced can be detected by radioactive energy levels and decay time. The original elements can be described from this behavior.

an investigation that focuses on aluminum content, an indirect measurement of clay content.

a pressure relief valve that opens when temperatures increases sufficiently to melt an activation linkage.

an activation log.

a log that detects compounds with oxygen such as water. Often used to detect channels behind pipe.
