The Tooth Fairy Project - RPHP has tested 4000 children's teeth for levels of radioactive Strontium-90. We found that average Sr-90 levels rose 50% in the 1990s, are highest near nuclear plants, and appear linked to childhood cancer trends.

Collecting and testing another 350 teeth this year will provide significant results near eight plants in the Northeast, California, and Florida.


The Child Cancer Tooth Study - As an outgrowth of the Tooth Fairy Project, we are conducting a study of Sr-90 in teeth of children with cancer (100 teeth have been donated thus far).

reliminary findings show average Sr-90 levels are considerably higher than those of healthy children. Collecting and testing an additional 200 "cancer teeth" will provide meaningful comparisons in Florida, New Jersey, New York, and Pennsylvania

The Long-Term Health Effects (Baby Boomers) Study (St. Louis Study) - Our third major focus is the result of an unexpected gift of 85,000 individually-identified baby teeth from Washington University in St. Louis. These teeth, not used in a landmark 1958-1970 study, give us the unprecedented opportunity to examine health effects of bomb test fallout on Baby Boomers. Identifying and testing teeth of 200 Boomers who have died and/or developed cancer by age 45, and comparing results to 200 healthy Boomers will provide a meaningful test on whether Sr-90 raises risk of death and cancer.
