Activation Analysis of Bromine by 14 MeV Neutrons in Activable Tracer Study of River Flow

Abstract

The activation analysis by 14 MeV neutrons of bromine contained in the river water was examined to be applied to the activable tracer method to study the flow problem of the river water, because the use of the neutron generators will be more easy than the use of the nuclear reactor.
The detection sensitivity of bromine is limited to be 1 ppm by the presence of ¹³N produced from oxygen.
It corresponds to the dilution rate of about 10⁶ if the concentration of tracer solution is 2.81 kg/10l NH₄Br and the volume of the water sample is 100 ml.
