Associated Particle Imaging (API) is a nuclear imaging technique that uses neutrons and gamma rays to create images of the inside of objects, allowing the elemental composition of materials to be accurately measured. It is used in various applications, from detecting explosives and illicit drugs to nuclear materials and diamonds.

However, uncertainties inherent to the technique can limit its use in applications that require high spatial resolution.

Now, researchers from the Accelerator Technology & Applied Physics (ATAP) Division at Berkeley Lab have developed a method for correcting distortions from center-of-mass (COM) movement in API. The work could extend API to measure the carbon content in soil from acre-sized fields on agricultural land at depths down to 30 centimeters. This would allow it to be used by farmers and landowners to claim credits for carbon sequestration activities, making it a powerful tool in the fight against climate change.
