Not only are we radioactive (with 3,500 potassium-40 decays per second as the original article states), we are also sources of antimatter. "Very rarely (0.001% of events), it decays to Argon-40 by emitting a positron (β+) and a neutrino." https://en.m.wikipedia.org/wiki/Potassium-40 https://en.m.wikipedia.org/wiki/Potassium-40
