Abstract
Systems and methods are provided for identifying an atomic element in proximity to an integrated circuit. Trace amounts of a contaminant are identifiable. The atomic element is exposed to neutron radiation to convert a portion of the atomic element into a radioactive isotope of the atomic element. Upsets are measured for the binary states of the memory cells of the integrated circuit during a time period following the exposure to the neutron radiation. The atomic element is identified from the upsets of the binary states of the memory cells of the integrated circuit.
