ROI Calculation Logic

Assuming annual re-inspection costs and personnel expenses for high-precision measurement are ~$35K (AI est.) with conventional technology, this technology could reduce those by 50%. Additionally, efficiency gains from reduced measurement time are estimated to save ~$135K (AI est.) in operational costs annually. Total estimated economic impact: (~$35K × 50%) + ~$135K = ~$150K/year (AI est.).

Speed to Market
4× faster than in-house development
This technology is a research outcome from a national R&D agency, with fundamental technical principles for nuclear material distribution measurement already established. Key algorithms for identifying alpha and beta radiation, extracting alpha-beta correlation events, and estimating background components are detailed in the patent specification, indicating high technical reliability based on empirical data. Therefore, adopting this patent could reduce the approximately 4-year in-house development period to about 1 year, enabling early market entry and business expansion for licensees.
