The United States of America, as represented by the Secretary of Agriculture; Carbon Asset Solutions (USA), Inc. has secured a major milestone in the mining industry with a newly patented system for detecting environmental contamination. This innovation focuses on the outstanding invention recently awarded Swanson Reed’s Patent of the Month for February 2026, titled ‘Methods and systems for measuring depleted uranium in soil using mobile gamma analysis’. The patent describes systems and methods for detecting depleted uranium contamination in a surface layer of soil comprising a gamma detector assembly, a location referencing mechanism, and a specialized processor configured to record, calculate, and compare gamma spectrum counts against environmental background thresholds.

Overcoming Depleted Uranium Contamination

This remarkable technology was recognized as Swanson Reed’s Patent of the Month for the Mining industry because it represents an outstanding invention that dramatically advances site remediation, environmental safety, and automated radioactive mapping in rugged terrain.

Meeting U.S. R&D Tax Credit Rules

To qualify for the U.S. Research and Development (R&D) Tax Credit under IRC Section 41, this innovation successfully satisfies the IRS Four-Part Test:

• Permitted Purpose: The research was undertaken to create a new and improved process for identifying and mapping depleted uranium, fundamentally enhancing environmental performance and detection reliability.
• Technological in Nature: The development process relies entirely on the hard sciences, specifically physics (gamma radiation detection) and computer science/software engineering (algorithmic processing of midpoint spectrums).
• Elimination of Uncertainty: Engineers faced initial technical uncertainty regarding how to accurately calculate midpoint spectrums between sequential mobile locations and reliably distinguish the target energy ranges from background gamma noise.
• Process of Experimentation: The team evaluated various processor configurations, tested different threshold calculation methods, and calibrated the gamma detector assembly iteratively to overcome those technical uncertainties.

Three Practical Applications Qualifying for R&D Credits

1. Algorithm Development and Software Engineering: Designing, coding, and iteratively testing the specific algorithms the processor uses to calculate midpoint spectrums and energy range counts. Experimenting with these logic sequences to ensure pinpoint accuracy in varying soil conditions qualifies as targeted R&D.
2. Hardware Integration on Mobile Platforms: Prototyping and testing the physical integration of the gamma detector assembly with the location referencing mechanism (e.g., GPS modules) onto mobile platforms like ATVs, rovers, or drones. The iterative testing required to maintain hardware stability and signal integrity over rough mining terrain directly addresses technical uncertainty.
3. Establishing New Site Remediation Protocols: Conducting field trials at former mining sites or military zones to optimize the mobile system’s operational parameters. Experimenting with different scanning traversal speeds, detector heights, and background threshold settings to maximize the system’s detection capability constitutes a qualifying process of experimentation.
