...open air one mile or less from the explosion's center. Cancer has been ten times more frequent in this group than among those who were inside shelters or situated farther from the explosion. Even among people exposed to a lesser degree of radiation, cancers of the thyroid, uterus and bone have developed in increasing numbers during the past decade. Numerous theories have been advanced over the years in an attempt to explain how radiation triggers cancer. The commission members hope that the cases of cancer in Hiroshima and Nagasaki will yield new clues...
...became seriously interested in football at the age of 14, when he grew to 5 ft. 11 in. and 150 Ibs., an advantage that helped him star in basketball, baseball, track and wrestling as well. At Stanford, though, his size almost caused a change in careers. Weakened by a thyroid operation, Plunkett was so unimpressive as a freshman quarterback that Coach John Ralston wanted to switch him to defensive end. But Plunkett was adamant. "I," he informed Ralston, "am a quarterback...
What makes radioisotopes so valuable is that they can be used selectively. Isotopes of iodine, for example, incorporate in the thyroid gland, where they can be used in both the detection and treatment of cancer, in some cases even eliminating the need for surgery. Fluorine, a related element, has a radioactive isotope (F18) that concentrates in bones, facilitating the detection of bone cancers...
...Bartter team started with two known facts. Parathyroid hormone, secreted by the thyroid's tiny satellite glands, directs the removal of calcium from bone and its release into the blood. One of the thyroid's own hormones, thyrocalcitonin, controls the converse-the transfer of calcium from blood to bone. These two hormones balance each other in normal metabolism by an exquisitely delicate feedback mechanism. Too little calcium in the blood signals the parathyroids to take some out of the bones and put it into circulation; a sufficiency of calcium in the blood induces a stop order from...
...Washington University in St. Louis, is a prolific lecturer and writer (Science and Survival) who brings an ecologist's insight and a polemicist's passion to the dangers of environmental pollution. "The new technological man," says Commoner, "carries strontium 90 in his bones, iodine 131 in his thyroid, DDT in his fat and asbestos in his lungs. There is now simply not enough air, water and soil on earth to absorb man-made poisons without effect. If we continue in our reckless way, this planet before long will become an unsuitable place for human habitation." At Washington University...
