Neutron activation analysis for sulphur in coal samples and moisture content by gamma-ray transmission

A neutron activation analysis method is described for the determination of sulphur in coal samples by analysing the beta spectrum emitted from 32P and 33P following the reactions 32S(n, p)32P and 33S(n, p)33P using 252Cf as a source of neutrons. The transmission of the combined gamma-rays emitted from three 137Cs and three 241Am sources is used to measure the water content of the coal samples. © 1993
