Radiation sensitive devices and systems for detection of radioactive materials and related methods
First Claim
1. A radiation sensitive device, comprising:
- a substrate comprising a radiation sensitive material exhibiting characteristics such that the radiation sensitive material at least partially ionizes when exposed to ionizing incident radiation; and
a plurality of resonance elements comprising a conductive material coupled to the substrate, wherein each resonance element of the plurality of resonance elements is configured to resonate responsive to non-ionizing incident radiation to produce an output signal, wherein at least one characteristic of the output signal changes responsive to the radiation sensitive material at least partially ionizing when exposed to ionizing incident radiation.

Abstract
Radiation sensitive devices include a substrate comprising a radiation sensitive material and a plurality of resonance elements coupled to the substrate. Each resonance element is configured to resonate responsive to non-ionizing incident radiation. Systems for detecting radiation from a special nuclear material include a radiation sensitive device and a sensor located remotely from the radiation sensitive device and configured to measure an output signal from the radiation sensitive device. In such systems, the radiation sensitive device includes a radiation sensitive material and a plurality of resonance elements positioned on the radiation sensitive material. Methods for detecting a presence of a special nuclear material include positioning a radiation sensitive device in a location where special nuclear materials are to be detected and remotely interrogating the radiation sensitive device with a sensor.
