Marie Curie is one of the few people to have won two Nobel Prizes and is the subject of a biographical film currently on Amazon. Among her many accomplishments is the discovery of radium-226 (in conjunction with her husband Pierre Curie). Radium-226 (atomic number 88) is an alpha-emitter with a half-life of 1600 years. Suppose you start with 10 units of radium-226. How much will remain after 8000 years? What has happened to the rest of the radium?

As one of the most famous scientists, Marie Curie has become an icon in the scientific world and has received tributes from across the globe, even in the realm of pop culture. In a 2009 poll carried out by New Scientist, she was voted the "most inspirational woman in science". Curie received 25.1 percent of all votes cast, nearly twice as many as second-place Rosalind Franklin (14.2 per cent).  Hope I helped! :)
