Abstract: An identification tag that is vulnerable to ionizing or non-ionizing radiation and system for determining the presence of radiation based on corrupted or altered memory in the tag is disclosed. An identification tag comprises: a transceiver for receiving an RF signal and transmitting a modulated RF signal; first memory containing a first code for generating the modulated RF signal, the first code being associated with an object for identification; and second memory containing a second code corresponding to a unique identifier for the tag for further modulating the received RF signal, the second memory being specifically vulnerable to ionizing or non-ionizing radiation such that the presence of ionizing or non-ionizing radiation alters or corrupts the second code, wherein the detection of the altered or corrupted code can be employed to indicate the presence of radiation.
