Abstract
Circuits which self-destruct under radiation are provided. In one aspect, a method for creating a radiation-sensitive circuit is provided. The method includes the step of: connecting an integrated circuit to a power supply and to a ground in parallel with at least one dosimeter device, wherein the dosimeter device is configured to change from being an insulator to being a conductor under radiation. Radiation-sensitive circuits are also provided.
Claims20
A radiation-sensitive circuit, comprising:
- an integrated circuit connected to a power supply and to a ground in parallel with at least one dosimeter device, wherein the at least one dosimeter device is configured to change from being an insulator to being a conductor under radiation to establish a direct connection between the power supply and the ground.
A radiation-sensitive circuit, comprising:
- an integrated circuit connected to a power supply and to a ground in parallel with at least one first dosimeter device and at least one second dosimeter device, wherein the at least one first dosimeter device is configured to change from being an insulator to being a conductor under a first type of radiation, and wherein the at least one second dosimeter device is configured to change from being an insulator to being a conductor under a second type of radiation.
