antineutrinos
Beta decay emissions
Antineutrinos are the antimatter counterparts of neutrinos—subatomic particles with no electric charge and nearly zero mass.
Like neutrinos, they interact so weakly with matter that trillions pass through your body every second without effect.
Antineutrinos are produced in nuclear reactions, particularly beta decay in reactors and radioactive materials.
They're used to monitor nuclear facilities and study fundamental physics.
