Methods and systems for sensing upon radiation exposure
First Claim
1. A method for sensing physical, chemical, and biological characteristics of an environment using a radio frequency identification (RFID) sensor component having a predetermined range of power initiation levels and having resonant circuit parameters comprising the steps of:
- activating the RFID sensor component and determining whether a range of power levels, needed for activating the sensor component, is more narrow than the predetermined range of power initiation levels;
sensing at least one of the physical, chemical, and biological characteristics of the environment;
quantifying the sensed characteristics of the environment using one or more selected resonant parameters, wherein the selection of parameters is based in part on the range of power levels needed to activate the sensor, wherein a change in the range of power levels that is needed to activate the sensor, is caused by exposure of the sensor component to gamma radiation.

Abstract
A method for sensing physical, chemical, and biological characteristics of an environment is provided. The method comprises using a radio frequency identification (RFID) sensor component having a predetermined range of power initiation levels and having predetermined resonant circuit parameters comprising the steps of activating the RFID sensor component and determining whether a range of power levels, needed for activating the sensor component, is below the predetermined range of power initiation levels; sensing at least one of the physical, chemical, and biological characteristics of the environment; quantifying the sensed characteristic of the environment using one or more selected resonant parameters, wherein the selection of parameters is based in part on the range of power levels needed to activate the sensor.
