Abstract
A method for the in vivo determination of body N by prompt .gamma. photons from neutron capture is described for humans. An 85-Ci 238Pu-Be source provides the neutrons. The .gamma. detection system consists of 2 15.24 .times. 15.24 cm NaI(T1) detectors placed above the patient. Absolute value of body N is determined using body H as an internal standard. The reproducibility of the method is .+-. 3% for a body dose of 26 mrem.This publication has 6 references indexed in Scilit:
