A method for determining ionizing radiation, comprising:
- exposing a device comprising a sensor material comprising a plurality of functionalized single-walled nanostructures and a polymer material integrally connected to at least a portion of the plurality of functionalized single-walled nanostructures to an environment suspected of containing ionizing radiation, wherein the ionizing radiation, if present, interacts with the polymer material such that at least a portion of the polymer material undergoes a change in polymerization characteristic, thereby generating a determinable signal;
- and
- determining the signal.
