Detection of gamma rays is shown using a non‐scintillating organic‐based sensor composed of poly(olefinsulfone)/carbonnanotube blends. Functionalization of the polymers can be performed after polymerization to tailor their structure with different pyrene and bismuth‐containing moieties not accessible by copolymerization, and a systematic improvement in sensitivity is achieved in this way.
