1. An article comprising:
a substrate;
a plurality of radiation sensors, each radiation sensor of the plurality of radiation sensors being disposed at a corresponding position on the substrate; and
alert circuitry coupled to the plurality of radiation sensors, wherein the alert circuitry indicates, in real time, a localized detection of radiation according to corresponding one or more positions on the substrate of a particular one or more radiation sensors of the plurality of radiation sensors, wherein the alert circuitry comprises a plurality of light sources, and wherein each light source is coupled to a corresponding one radiation sensor of the plurality of radiation sensors and located within a region of the corresponding position of the radiation sensor on the substrate.
