a log device that emits a burst of tracer and tracks its movement. May “see” a foot or so outside casing in good circumstances. Normal for injection wells.

n: a survey that uses a radioactive tracer such as a gas, liquid, or solid having a high gamma ray emission. When the material is injected into any portion of the wellbore, the point of placement or movement can be recorded by a gamma ray instrument. The tracer log is used to determine channeling or the travel of squeezed cement behind a section of perforated casing. Also called tracer survey.

a log that uses radioactive tracer to monitor fluid movement in the wellbore or measure losses from the wellbore.

a log that uses a spectral gamma ray and multiple marked sand tracers to analyze proppant placement.

n: A kind of logging ways that using gas ,liquid or solid containning high gamma ray as radioactive tracer.
