in-vivo neutron activation analysis

https://doi.org/10.1351/goldbook.08731

Measurement method of neutron activation analysis in which a living organism is exposed to neutrons to measure the concentrations of elements in that living organism.

Notes:
  1. The neutrons are typically provided by a neutron beam.
  2. Often prompt gamma-ray analysis is used to measure half-value thickness, rather than the activity of neutrons produced.
