AbstractStrontium-90 concentrations in baby teeth of 515 children born mainly after the end of worldwide atmospheric nuclear bomb tests in 1980 are found to equal the level in children born during atmospheric tests in the late 1950s. Recent concentrations in the New York-New Jersey-Long Island Metropolitan area have exceeded the expected downward trend seen in both baby teeth and adult bone after the 1963 ban on atmospheric testing. Sharp rises and declines are also seen in Miami, Florida. In Suffolk County, Long Island, Strontium-90 concentrations in baby teeth were significantly correlated with cancer incidence for children 0 to 4 years of age. A similar correlation of childhood malignancies with the rise and decline of Strontium-90 in deciduous teeth occurred during the peak years of fallout in the 1950s and 1960s. Independent support for the relation of nuclear releases and childhood cancer is provided by a significant correlation with total alpha and beta activities in local surface water in Suffolk County. These results strongly support a major role of nuclear reactor releases in the recent increase of cancer and other immune system related d isorders in young American children since the early 1980s……….
Sr-90 Concentration in Baby Teeth, St. Louis vs. Cancer Incidence Age 0-4, Connecticut 1954-1970
Sr-90 Adult Dietary Uptake, New York City vs. Cancer Incidence Age 0-4, Connecticut 1954-1970
* Connecticut cancer rates represent 3-year moving averages
Fetuses can be harmed by very low dose radiation, first demonstrated in the 1950s when exposure to pelvic X-rays in utero was linked with elevated levels of leukemia and cancer deaths before age ten. (13) (14)
