Each October, the Nobel Prizes celebrate remarkable scientific achievements, some of which have their origins in unconventional places. In the case of George de Hevesy, who received the Nobel Prize in Chemistry in 1943 for his groundbreaking work on radioactive tracers, that unconventional place was a boarding house cafeteria in Manchester, U.K., in 1911.
De Hevesy’s Cafeteria Experiment
George de Hevesy had a hunch that the boarding house cafeteria staff was reusing leftovers from previous meals, as the daily soup seemed to contain the same ingredients as the day before. To test his theory, he used a small amount of radioactive material in his leftover meat. A few days later, armed with an electroscope, he measured the radioactivity in the prepared food. When he showed the results to his landlady, who was unwittingly serving recycled food, she exclaimed, “this is magic.” In reality, it was the inception of the first successful radioactive tracer experiment.
Revolutionizing Science with Radioactive Tracers
Fast forward to today, where we, a team of chemists and physicists at the Facility for Rare Isotope Beams, Michigan State University, continue to build upon de Hevesy’s early research. His work has revolutionized the way modern scientists use radioactive materials, leading to numerous scientific and medical advances.
