The St. Louis Tooth Fairy Study


The Radiation and Public Health Project is conducting research to estimate cancer risk from exposure to atomic bomb test fallout measuring radioactive Strontium-90 (SR-90) in baby teeth. The study is based on 85,000 baby teeth discovered by researchers at Washington University in St. Louis. The teeth were collected for the original Tooth Fairy study (1958-1970) and had been in storage for over three decades before being released to RPHP.

RPHP will release results of the study in late June. Read more about this important study here.
