Atomic Tests in 1950s Create Need for First Tooth Studies
Studying radiation in baby teeth was an unknown technique when U.S. atmospheric nuclear weapons tests started. By the mid-1950s dozens of weapons had been detonated, including hydrogen bombs one thousand times more potent than atomic bombs. The 422 American and Soviet nuclear explosions into the atmosphere during the arms race equaled the yield of 40,000 Hiroshima bombs.
Fallout from bomb tests consisted of over 100 radioactive and cancer-causing chemicals, not found in nature. Each chemical affects the body differently. Iodine-131 attacks the thyroid gland, Cesium-137 disperses into all soft tissues, and Strontium-90 attaches to bone and teeth. The mushroom clouds in Nevada moved eastward with prevailing winds across the continent, where fallout re-entered the environment through precipitation. Scientific measurements showed that only 2 or 3 days after a Nevada explosion, fallout from the test could be present in rain or snow throughout the country, even the east coast 2500 miles away.
Soon after the Nevada tests began, the U.S. Atomic Energy Commission began the first program measuring radioactivity levels in human bodies by testing Strontium-90 in bones from autopsies in the U.S. and in Europe. The AEC program showed that Sr-90 levels varied by geographic area, and were greater in infants and children. (1) The program also became infamous for its failure to request family permission before testing skeletons. (2)
Although Sr-90 was just one of the 100-plus chemicals in fallout, it quickly became the favorite for in-body testing, as its half life of 28.7 years makes it detectable for a long period after a bone or tooth is extracted from the body. But Sr-90 was also recognized as one of the most harmful components of the clouds. It was known to penetrate into the bone marrow, where red and white blood cells crucial to the immune response are formed....
