Abstract

A method for the rapid analysis of carbon and oxygen in steel, using fast neutron inelastic scattering and fast neutron activation, respectively, is presented. A small deuterium-tritium generator is used as the neutron source, and an NaI(Tl) scintillation detector is used to detect the gamma rays produced. The results of Monte Carlo simulation are reported for two types of geometry: a transmission geometry in which a source and a detector are placed at opposite sides of the sample, and a backscatter type in which a source and a detector are on the same side of the sample. The accuracy and robustness of the method are discussed. The computer calculations show that the accuracy of carbon measurement is ±0.1 wt% (3 σ) in the range of 0.4-2.5 wt% for 60 s of counting in both the transmission and the backscatter geometry. The accuracy of oxygen determination is ±0.01 wt% (3 σ) in the range of 0.1-0.2 wt% for 60 s of counting, following 60 s of irradiation, in both cases.
