Another confirmation of hormesis:
"Radiation: it may be good for us. That is the conclusion of Taiwanese scientists who surveyed thousands of people exposed for years to radiation after recycled steel, contaminated with cobalt-60, was used to build hundreds of apartment blocks in the country. The scientists say their findings suggest radiation could be used to prevent illness and help elderly people build their natural defences against cancer.
The "serendipitous contamination" began in the early 1980s when the steel was used to build 1700 apartments. About 10,000 people lived in them for between nine and 20 years, unaware they were receiving, on average, 200 times the radiation an Australian would expect to receive in a year. But the scientists, including several employees past and present of Taiwan's Atomic Energy Council - criticised over the contamination scandal - say the residents were not harmed. "On the contrary," they claimed in a report last month to an international nuclear conference in Honolulu, "the incidence of cancer deaths in this population was greatly reduced - to about 3 per cent of the incidence of spontaneous cancer death in the general Taiwan population. "In addition, the incidence of congenital malformation was also reduced - to about 7 per cent of the incidence in the general public."
The radiation-haters have a few quibbles about the study but only 3% of the normal cancer incidence makes the quibbles look pretty desperate -- particularly where they would have predicted more like 300% of the incidence. And the desperation of the quibbles grows when we know that there is roughtly a century of evidence for the beneficial effects of mild ionising radiation. An example perhaps even more dramatic than the Taiwanese one is that people on the outskirts of the Hiroshima and Nagaski blasts had exceptionally healthy subsequent lives.
So why do the panic merchants hate the very idea of radiation hormesis? Because it means that the Three Mile Island and Chernobyl events probably did more good than harm -- which deprives the Greenies of an excuse to inflict great costs on us all. And it shows that limitless energy from nuclear power is safely available to us -- thus derailing all their prophecies of economic doom.
There is a heap of scientific links on the subject here but a Google search using just the term "hormesis" will turn up many more. Note also that there have been three big US government research projects that showed LOWER death rates among people exposed to plutonium: The studies are in the report: "Toxicological Profile for Plutonium," prepared for and issued by Agency for Toxic Substances and Disease Registry, Centers for Disease Control, Atlanta, Georgia, in collaboration with U.S. Environmental Protection Agency, December 1990.
