We have demonstrated a new way to reveal the electrical ‘fingerprint’ left by a single nuclear decay. When a radioactive atom implanted just beneath a surface decays, its products can eject a shower of secondary electrons from the surrounding material. Often undetected by conventional laboratory instruments, these electrons can create a substantial background in experiments that rely on precise electron counting. To study this process, we use a microscopic glass sphere suspended by laser light as a highly isolated charge detector with sub-electron charge sensitivity. We pair the sphere with a conventional scintillation detector that records the emitted radiation. By matching the timing of the two signals, we can link each charge change to a specific decay. We found that one alpha decay can knock more than 100 electrons from a material’s surface, while beta decays release far fewer. Measuring these electrical fingerprints one decay at a time could help experiments searching for rare events, including future sterile neutrino searches, to distinguish genuine signals from electrons released by radioactive impurities near detector surfaces.

Discovering new isotopes begins with knowing where to look. Predicting rare-isotope production is difficult because different nuclear-mass models can give substantially different results, making the planning of experiments uncertain. This work introduces a Bayesian-inspired model-averaging framework that combines abrasion–ablation calculations based on 12 nuclear mass tables into one statistically weighted prediction. Experimental data for krypton-78 and xenon-124 are used to determine which calculations are more reliable, and the resulting trends are transferred to molybdenum-92 and samarium-144 projectiles. The method provides predicted cross sections together with uncertainty estimates, giving a more reliable basis for selecting primary beams and estimating yields. Applied to proton-rich fragmentation at FRIB, the approach identifies several promising candidates for new-isotope searches with expected production rates above one event per day. It can help researchers plan experiments more effectively and explore still-unknown regions of the nuclear chart.
