What is a picocurie? A picocurie is a unit of measurement of radioactivity, equal to the amount of a radioactive isotope that decays at the rate of 3.7 × 10=10¹disintegrations per second. It was named after Marie Curie, a Polish born chemist who shared the Nobel Prize in 1903 with her husband Pierre Curie and Henri Becquerel for their collaborative research on radioactivity. In addition, Madame Curie won a second Nobel Prize in 1911 for her discovery and study of radium and polonium now found in the periodic table of chemical elements.
