Abstract
RFID tags that must operate in the presence of ionizing radiation need to be radiation hardened in order to achieve reliable operation. This disclosure teaches several RFID tags that achieve radiation hardening without requiring the use of special-purpose radiation-hardened electronic devices. RFID tags typically use an antenna made of metal for achieving reliable radio communications. Radiation hardening is achieved by shaping the antenna such that the metal of the antenna acts as a shield for the radio circuits.
