  1. The measurement of silicon in a lung phantom : a comparison of two nuclear reactions for in vivo activation analysis.

    Article - En anglais

    The amount or silica in the human lung may be estimated by measurement or silicon using in vivo neutron activation analysis.

    A pulsed, fast neutron beam. produced with a 2 MV Van de Graaff generator using the 2H+2H reaction, was used to irradiate a Si-doped chest phantom in order to determine minimum detection limits (MDL).

    Two « in-beam » nuclear reactions on Si were studied; prompt fast neutron inelastic scatter 28Si (n,n'gamma)28Si reaction was measured during the beam burst and the slow neutron prompt capture reaction was measured between the fast neutron bursts.
