"Calling all Tooth Fairies: The Radiation and Public Health Project (RPHP) wants your children&amp;#8217;s baby teeth for their Tooth Fairy Project. The unusual research project measures the levels of strontium-90&amp;#8212;a radioactive isotope that deposits itself inside bones and teeth like calcium&amp;#8212;to determine the nuclear radiation levels in a given area. The Radiation and Public Health Project is a watchdog group with an eagle eye on radiation levels, nuclear power plants and the fallout from the Chernobyl disaster. According to RPHP, most of the strontium found in baby teeth is transferred to the fetus during pregnancy by the mother. That&amp;#8217;s why they&amp;#8217;re looking for baby teeth in particular.  To participate in the Tooth Fairy Project, follow the link below."^^<http://www.w3.org/2001/XMLSchema#string>
