Carbon analysis of large soil samples using the tagged neutron method: Accounting for radiation attenuation

Appl Radiat Isot. 2024 Apr 25;209:111332. doi: 10.1016/j.apradiso.2024.111332. Online ahead of print.ABSTRACTNon-destructive methodology for determining carbon content in large or semi-infinite (soil) samples is discussed. This methodology is based on deconvoluting the sample's gamma spectra (received by tagged neutron method) on the sample component's spectra by accounting for neutron and gamma radiation attenuations. This algorithm was tested with both Monte-Carlo simulations and experimental gamma spectra. Good agreement was found between defined and actual sample component content. Application of this method for soil carbon determinations in agricultural fields is discussed.PMID:38696919 | DOI:10.1016/j.apradiso.2024.111332
