UNSCIENTIFIC RADIATION PANIC

I have put up many posts pointing out that radioactivity is actually good for you in moderate doses. Here are some extracts from Jerry Pournelle's site which also point that out:

In 1983 a group of 180 apartment buildings was completed in Taiwan. Somebody had made a serious mistake. They had mixed into the concrete a considerable amount of highly radioactive cobalt 60. This meant that ultimately 10,000 people lived in buildings for from 9 to 20 years so radioactive that they received an average of 74 mSv of radiation per year in 1983, declining thereafter as cobalt 60 has a half life of 5 r years. This compares with a rate of 0.5 mSv above background which is the normal maximum exposure for radiation workers & total of 15 mSv maximum safe limit for land fit for habitation according to US government standards.

According to the linear no threshold (LNT) theory currently in use world-wide for assessing nuclear risks there is no lower limit to the level at which radioactivity kills (hence the term "no threshold") & this, inhabited for a decade & a half before the radioactivity was traced & measured, should be the site of a truly massive cancer death rate.

It isn't.

A thorough & methodical tracing of all the 4,000 families by a team led by W. L Chen of Taiwan's Director of Medical Radiation Technology of Taiwan's National Yang-Ming University (the full report is available in English here ) has resulted in an unequivocal & spectacular result. Cancer rates in that highly radioactive building are down to 3.6% of prevailing Taiwanese rates.

For many years there has been an unfashionable alternative to the LNT theory called hormesis. This is an effect, long observed in plants & cultures, whereby intermediate level radioactivity actually stimulates life & improves health. There has been significant evidence for this (the deaths at Hiroshima did not appear to fit the LNT pattern, there are places in India & Iran with background radiation of 15mSv or higher with no observed increase in cancer & numerous studies of radon in homes have found a reverse correlation between radon levels & cancer). Nonetheless, such has been our fear of all things nuclear that the LNT theory has been absolutely accepted despite the fact that there has NEVER been any actual evidence for it.....

For many years the NRDC and other "pro-environment" groups have insisted that all radiation is dangerous no matter what the level, and cumulative as well, so that the only safe action is to eliminate radiation. Of course there is natural radiation, which varies from place to place; sealing one's house allows radon to accumulate, raising the radiation in the house, sometimes to surprising levels; and going to higher altitudes always results in higher exposures, so much so that airline crews get quite a lot of radiation exposure, enough to be of concern.

The NRDC hasn't quite said that we must evacuate Denver and Colorado Springs as dangerous radiation hazards, but such a policy would be logical, given their "scientific" assumptions. The alternative theories of radiation are the ancient pharmaceutical doctrine "The dose makes the poison," (i.e. that a some low enough level radiation is irrelevant), and "hormesis", which combines the "dose makes the poison" doctrine with the not entirely intuitive discovery that at low enough levels, radiation is actually good for you.

The hormesis hypothesis has been confirmed many times. One study was by the Swedish Army, which accumulated data on conscripts (Sweden has universal manhood conscription) from areas of known high radiation and compared their health statistics to recruits from areas matched in other characteristics. The conclusion was very much in favor of the hormesis theory. One participant in the study was Claes-Gustav Nordquist, the Surgeon Colonel of the Lifeguards Regiment who was until his retirement one of the leading oncologists in Sweden. There have been many others, but Claes is an old friend so I learned a good bit about the details of that study.

Despite the plethora of data confirming hormesis, the "environmental" movement continues to insist on the LNT (Linear, No Threshold) theory and this is one of their reasons for opposition to nuclear power as an alternative to fossil fuels.






Activists, not global warming, the third world threat

A coalition of environmental activists called this week for rich countries to do more to control global warming and to help poor nations cope with the alleged effects of climate change

The irony, of course, is their activism, not global warming, is the real threat. The activist groups, including Greenpeace, Friends of the Earth, Oxfam and ActionAid, issued a report calling for cuts in greenhouse gas emissions far more stringent than those called for by the international global warming treaty known as the "Kyoto protocol". They also want industrialized countries to subsidize poor countries' adaptation to global warming to the tune of $73 billion per year, a sum on par with what industrialized countries now pay in subsidies to their domestic fossil fuel industries, according to the report.

Keep in mind that the Kyoto protocol, rejected by the U.S. Senate, President Bush and even Sen. John Kerry, only called for cuts in greenhouse gas emissions in the U.S. of about 7 percent below 1990 levels - cuts that the Clinton-administration Department of Energy estimated could raise electricity prices 86 percent and gasoline prices 53 percent. Greenpeace and company now want greenhouse gas emissions to be cut by 60-80 percent from 1990 levels - cuts that would probably be economically devastating to the developed world

The activists' recipe for solving global warming thus appears to be, first, to kill off economic development in the developed world and, then, to have the developed world send what money it has left over to the developing world. It's not clear, though, that an economically crippled developed world would be able or willing to subsidize poor countries, leaving those countries forever impoverished.

While no one knows whether or to what extent humans may or may not be affecting global climate, climate change is a known and natural fact. The advantage that humans have over other species is that we can use our intelligence and wealth to adapt to changes in climate. Air conditioning, irrigation, desalinization are examples of human ingenuity overcoming otherwise inhospitable or uncomfortable climactic conditions. But harnessing technology to overcome climate challenges requires money - something that is often in short supply in poor countries. And, sadly, the environmental activists seem to be doing their best to make sure that poor countries stay poor.

For example, in a Jan. 22 media release, the activist Rainforest Action Network (RAN) "declared victory in its campaign to transform the environmental practices of the world's largest financial institution, Citigroup." Now Citigroup doesn't have the sort of "environmental practices" typically associated with manufacturing and chemical industries. But Citigroup does make loans for economic and industrial development. After a four-year-long campaign, the RAN pressured Citigroup to restrict its lending practices in the developing world, including: not lending to projects that might adversely impact natural habitats; banning logging in tropical forests; avoiding investment in fossil fuel energy projects; and reporting greenhouse gas emissions from power projects in its lending portfolio.

It's an extremely regressive lending policy that, in effect, gives environmental activist groups a veto on Citigroup loans for development in poor countries - and we all know how much environmental activists approve of development. The Rainforest Action Network is not stopping with Citigroup.

Many people would like to be kind to others so Leftists exploit that with their nonsense about equality. Most people want a clean, green environment so Greenies exploit that by inventing all sorts of far-fetched threats to the environment. But for both, the real motive is to promote themselves as wiser and better than everyone else, truth regardless.
