Abstract.A new method based on PGNAA technique has been proposed for moisture content and elements concentration determination in landfills. Due to the complexity of MSW component, the compounds of polyethylene balls, glass balls and water were selected as the MSW alternatives for research. By changing the proportion of polyethylene and glass ball, water contents of five samples were regulated to 40.522%, 47.575%, 55.168%, 63.369%, 72.251%, respectively. Based on a new set-up was developed to validate the method by MCNP simulations and experimental researches. The results show that the counts of hydrogen peak increase with the increase of the moisture content for samples, and good linearity can be figured out between the counts of hydrogen peak.

“…5 The optimization concerned the dimensions of the Perspex sample cylindrical container. In this set-up, the 1 Ci Am-Be neutron source emitting around 2.2x10 6 n/s is confined in a Perspex tube immersed in the center of the sample. The maximum average thermal neutron flux was looked for in the sample with the constraints that neutron damage, neutron and gamma rays doses, and pulse pile-up must be at reasonable levels.…”

An experimental PGNAA set-up using a 1 Ci Am-Be source has been developed and used for analysis of bulk sewage sludge samples issued from a wastewater treatment plant situated in an industrial area of Algiers. The sample dimensions were optimized using thermal neutron flux calculations carried out with the MCNP5 Monte Carlo Code. A methodology is then proposed to perform quantitative analysis using the absolute method. For this, average thermal neutron flux inside the sludge samples is deduced using average thermal neutron flux in reference water samples and thermal flux measurements with the aid of a 3 He neutron detector. The average absolute gamma detection efficiency is determined using the prompt gammas emitted by chlorine dissolved in a water sample. The gamma detection efficiency is normalized for sludge samples using gamma attenuation factors calculated with the MCNP5 code for water and sludge. Wet and dehydrated sludge samples were analyzed. Nutritive elements (Ca, N, P, K) and heavy metals elements like Cr and Mn were determined. For some elements, the PGNAA values were compared to those obtained using Atomic Absorption Spectroscopy (AAS) and Inductively Coupled Plasma (ICP) methods. Good agreement is observed between the different values. Heavy element concentrations are very high compared to normal values; this is related to the fact that the wastewater treatment plant is treating not only domestic but also industrial wastewater that is probably rejected by industries without removal of pollutant elements. The detection limits for almost all elements of interest are sufficiently low for the method to be well suited for such analysis.

“…Its area of application includes on-line and in situ measurement, environment and non-destructive analysis (Naqvi et al, 2009(Naqvi et al, , 2004Idiri et al, 2010;Ling et al, 2015;Révay and Molnár, 2003;Révay and Kennedy, 2012). The method is based on the measurement of prompt gamma rays emitted following thermal neutron capture and inelastic scattering reactions by the element present in the sample.…”
