Abstract

The neutron moderating effect of concrete and polyethylene mixtures on the determination of the sample composition was investigated by irradiating 200 L steels drums with 14 MeV neutrons at the MEDINA (Multi Element Determination based on Instrumental Neutron Activation) facility. The elemental composition was evaluated using a quantification model validated for a concrete matrix in a previous work. The results obtained were found to agree with the expected values within ±34 % which is reasonable with regards to the samples heterogeneity.
