Those college kids made up that website as a dig at the breathless scare mongering by so many ecofreaks. The whole site is a sendup of that silliness. I find it very humorous. đ

Said mischief is not inherent in the principle itself, but how it is used. Since anyone can come up with a âwhat if âscenario, the principle ends up applied indiscriminately. Just as John Woodgate describes, we have in place in the USA laws that prohibit any concentration of certain chemicals. These laws were passed when the ability to see a concentration might have been in the parts per million, but we have progressed to measuring parts per trillion, and the laws havenât changed. If someone raises the issue of changing the law to allow some concentration above what is measurable, they are labeled as advocating pollution of the water supply, or air or whatever. As is often noted, âthe dose is the poison.â Many things which are poison in large quantities are beneficial at lower levels. Aspirin comes to mind. Some time in the early â90s the keynote speaker at a US-based IEEE EMC symposium was someone active in EMF effects on health. He went so far as to say that in addition to eliminating EMF due to overhead power lines, and the like, we could not simply hide in a shield room, because our bodies evolved to live in an environment not totally free of EMF, so that totally eliminating them would be as problematical as too much. Consider the âthoughtâ process here. Human beings evolved to survive with a life span of about 35 years. In the Stone Age, by 35 you were a grandparent and arthritis, rheumatism, and the other ills of old age had combined to make you a drag on the tribe. Discovery of Neanderthal man at first had them bent over and âIgorâ like. It wasnât until much later they realized that the skeletons had been ravaged by rheumatism/arthritis. The mistake was made because they could tell these people had died in their thirties, and that was deemed too early for these ills, so that they assumed these people were naturally misshapen. In the USA at the beginning of the 20th century average life expectancy was in the forties. All those cowboys smoking in the old westerns made perfect sense â the last thing those guys expected to die of was emphysema or heart disease or cancer. The original USA social security retirement age of 65 was set to coincide with the mean date of expiration of the human body determined at that time. A policy aimed at improving physical health and longevity but predicated on how we evolved is inherently flawed. Those of us past 35 or so are in uncharted waters as to what does or does not promote or constrain longevity.

This says that if you don't know the harmful level of something, you reduce its level to ALARP, 'as low as is reasonably practicable'. Unfortunately, of course, opinions differ very widely on what that level is, in many cases. This is why we see concentration limits of parts per trillion, because they are achievable (at a price), not because they are related to known effects. I didn't grow up in strong EM fields, but in a concentration of lead (pipes, paint, cable sheaths) that would be regarded as horrifying now.

Much of the interest in Europe was generated by Scandinavian trades unions concerned about 'radiation' from CRT displays. Adverse health effects of a general nature (headaches, insomnia, general malaise) were very likely much more due to poor working conditions and job interest, but the unions are very powerful. You can't subject people to increasingly strong fields until they show a reaction, it would be highly unethical.
