How Do RFID Labels Behave in High-Radiation Areas?
They tend to behave badly. They often become forgetful and lazy.
Sorry, what I mean is that their memory can be wiped out by the radiation and the circuitry can be damaged, causing the tag to become unresponsive. You would, therefore, need to use a special transponder designed to withstand radiation.
Tego, in 2011, introduced an EPC Gen 2 ultrahigh-frequency (UHF) tag that can withstand exposure to high levels of X-ray and gamma radiation, as well as other types of electromagnetic radiation, such as that present in the nuclear energy and defense sectors (see Tego Introduces Radiation-Resistant EPC Tag).
Smartrac, an RFID inlay supplier headquartered in Amsterdam, The Netherlands, created an RFID transponder that, according to the company, is able to withstand gamma radiation levels of up to 45 kilograys. Smartrac says the transponder—a high-frequency (HF) 13.56 MHz technology that complies with the ISO/IEC 15693 standard—is designed for use in medical applications in which aseptic conditions are compulsory (see RFID News Roundup: Smartrac Launches Gamma Radiation-Proof RFID Tags).
And the Argonne National Laboratory was able to modify the ST-676 active 433 MHz tag, made by Savi Technology, to withstand exposure to high levels of radiation (see U.S. Department of Energy Employs RFID to Safeguard the Country).
