The Tooth Fairy Project is a pseudoscientific research project[1] undertaken by an anti-nuclear organization called Radiation and Public Health Project. It intends to demonstrate that routine emissions of very small amounts of radioactivity from nuclear power plants have a measurable impact on the health of people living near those facilities. The project's activities are supported by the movie star Alec Baldwin[2] and some other misguided celebrities.

[edit] Outline

The study involves collecting the deciduous teeth of babies, both those which were shed recently and those saved as a memoir by parents, The date of birth and the location where the child was carried to term and raised is recorded. The activity of strontium-90 in teeth is measured, and an attempt is made to find a correlation with the location of nuclear power plants. Several non-peer-reviewed papers were released by the project, with all of them claiming an increased level of strontium-90 in baby teeth, and postulating increased cancer risks for people living near nuclear facilities.

The parent organization received a donation of baby teeth collected by a legitimate long term study in the years 1958-1970, which investigated the uptake and health effects of strontium-90 from atmospheric nuclear testing.[3] The relevance of this data set to the project's central claim is extremely tenuous, as most of the strontium-90 accumulated in those teeth can be expected to originate from nuclear testing.

[edit] Why it is bogus

More than 99% of strontium-90 in the environment comes from atmospheric nuclear testing fallout from the 1950s and early 1960s. Strontium emissions from nuclear power plants are very low - at or below detection levels. Note that radioactive substances are often used as tracers precisely because they can be detected at extremely low concentrations using relatively simple equipment. The total radiation dose (strontium, iodine, xenon, etc.) from routine emissions from nuclear power plants is only 0.01% of the natural background radiation dose.[citation needed]

In addition to this common sense argument, there are several more specific flaws in the studies. Here are the ones identified by the US Nuclear Regulatory Commission:[4]

  • Inadequate control populations or lack of them.
  • No consideration of risk factors other than strontium.
  • Very small sample sizes used to draw general conclusions.
  • Data that did not fit the pre-determined conclusions were considered artifacts and excluded from further analysis.
  • Wrong half-life used for strontium-90.

[edit] What real science says

The definitive large scale study on cancer near nuclear facilities in the US was conducted by the National Cancer Institute and completed in 1991. It found that the relative risk of living in US counties that had nuclear facilities dropped by a non-significant amount after the facilities were started; nuclear displaces fossil fuels, emissions of which are less healthy and more radioactive than nuclear. Overall it found no evidence of an increase in cancer mortality. The facilities investigated included power plants, DoE research and weapons sites and a fuel reprocessing plant.[5] A similar study in 1987 in UK found the same conclusion; the exception was childhood leukemia, but its increased incidence cannot be attributed to excess radiation.[6] There is credible evidence that suggests that migrations to newly formed service towns and the associated rise in infections are the real cause of the childhood leukemia increase.[7][8]
