The detection limits for determination of Br in blood serum by epithermal neutron activation analysis and comparison of the method with other methods of neutron activation analysis are reported. A calibration curve for 0.1-1.5 ..mu..g of bromine determined by this neutron activation analysis method was found to be linear over this range, and the sensitivity obtained from this curve was found to be 19,931+/-150 counts/..mu..g Br. For 0.2-ml samples irradiated for 20 min after a decay time of 5 min, the detection limits for determination of Br by ..gamma..-ray and x-ray spectrometry was 37 and 46 ng/ml, respectively. The lower detection limit noted for ..gamma..-ray spectrometry and the self-absorption of x-ray measurements make the ..gamma..-ray detection the preferred method for detection following epithermal neutron activation.
