Latest Patents

Harrison’s patent, “Real-Time Change Detection Monitoring Using Isotopic Ratio Signatures,” describes a system and method for remotely monitoring an irradiated salt mass within a decay enclosure. The approach measures the mass ratio of two radioisotopes with different half-lives. One isotope has a shorter half-life than the enclosure’s effective half-life, while the other has a longer one.

According to the patent description, diversion causes the measured ratio to move quickly outside a target range and remain below it for several years. This rapid and lasting change can serve as an indicator of inventory loss, supporting efforts to detect diversion of irradiated salt that could pose a proliferation risk.
