POLYMER NUCLEAR RADIATION DETECTOR

摘要

A radiation detector (1) comprises a layer (2) of polymer-nanoparticle composite (PNC) material on a substrate (3). Top and bottom electrodes (4, 5) allow a voltage to be applied through the layer (2) of PNC material and for a current generated between the electrodes (4, 5) when nuclear radiation is incident on the layer (2) to be detected. The PNC material is typically a composite of an organic polymeric substance comprising a dispersion of colloidal particles of an acrylic copolymer composition in water, e.g. latex, and carbon nanotubes (CNTs).
