Curie

/ -riː, kyri, ˈkjʊərɪ /

Marie (mari). 1867–1934, French physicist and chemist, born in Poland: discovered with her husband Pierre the radioactivity of thorium, and discovered and isolated radium and polonium. She shared a Nobel prize for physics (1903) with her husband and Henri Becquerel, and was awarded a Nobel prize for chemistry (1911)
her husband, Pierre (pjɛr). 1859–1906, French physicist and chemist

curie

/ ˈkjʊərɪ, -riː /

Ci.��a unit of radioactivity that is equal to 3.7 × 10 ¹⁰ disintegrations per second

Curie

Polish-born French chemist who pioneered research into radioactivity. Following Antoine Henri Becquerel's discovery of radioactivity, she investigated uranium with her husband, Pierre Curie (1859–1906). Together they discovered the elements radium and polonium. Marie Curie later isolated pure radium and developed the use of radioactivity in medicine.

curie

A unit used to measure the rate of radioactive decay. Radioactive decay is measured by the rate at which the atoms making up a radioactive substance are transformed into different atoms. One curie is equal to 37 billion (3.7 × 10 ¹⁰) of these transformations per second. Many scientists now measure radioactive decay in becquerels rather than curies.
