Abstract
In this paper a non-destructive technique Neutron Resonance Transmission Analysis (NRTA) is presented and demonstrated. The technique has been applied at the Time-Of-Flight facility GELINA of the Institute for Reference Materials and Measurements at Geel in Belgium to characterize a radioactive PbI 2 sample, which was used to study the transmutation capabilities of 129I. A transmission experiment divided into three measuring sequences allowed the identification and quantification of light ( 16O, 23Na and 32S) and heavy nuclei ( 127I, 206Pb, 207Pb and 208Pb) with an accuracy better than 7%. In addition, an upper limit of the hydrogen content was deduced from the attenuation of the neutron beam by the non-resonant scattering contribution.
