Elevated strontium-90 levels found in babies’ teeth correspond to nuclear tests and accidents

The Tooth Fairy Project and other studies like it prove that nuclear tests and accidents result in widespread exposure to radioactive materials.

All published studies tell a similar story; peak levels were reached in the mid-1960s, when the huge amounts of Sr-90 released in the final massive US/USSR hydrogen bomb tests of 1962 finally rained out by 1964 and 1965.

In the 1970s, Sr-90 levels in baby teeth dropped back down to about 1 pCi/grCa, about the same level reached in the US by 1958. Studies published by Denmark and Japan were continued until the early 1980s, suggesting that sometime in the mid-1970s the strontium-90 levels in teeth leveled out, followed by a slight upturn.

However, a current study of some 6,000 German baby teeth collected since 1992 by the German Section of the International Physicians for the Prevention of Nuclear War–winner of the 1985 Nobel Peace Prize Award–found the trend has changed.

The German Section of the International Physicians for the Prevention of Nuclear War found a tenfold increase in the teeth of German children born in the period following the arrival of Chernobyl fallout in May of 1986, as compared with children born in 1983.

RPHP has translated and published the first IPPNW report: Ten Years After Chernobyl: The Rise of Strontium-90 in Baby Teeth .

Our own study replicates the IPPNW protocols, in securing for each tooth analyzed the birthdate and place of birth of each child. As of April 2003, we have collected 4000 teeth.
