On the Radiolytic Stability of Potentiometric Sensors with Plasticized Polymeric Membranes

There is not much known on the stability of plasticized polymeric sensor membranes against ionizing radiation. While recent studies have indicated applicability potentiometric sensors with such for quantification actinides and lanthanides in spent nuclear fuel reprocessing solutions, real industrial application will require their radiation fields. The present study explores this problem evaluates sensitivity towards a variety based different neutral ligands. We demonstrate that most studied compositions retain up to 50–100 kGy absorbed gamma dose. higher doses lead gradual loss due radiolysis ligands polymer membrane matrix as confirmed by electrochemical impedance magnetic resonance studies.
