A Scientist On Relative Effects Of Different Toxic Exposures

A really interesting look at important issues and exposing some pseudoscience and overly fearful environmentalism.  Here is the description of the videos from the YouTube information bar:

Chemical toxins are a real health risk. So is radiation. But should we be extrapolating the effects of certain toxins at high doses down to a low-level exposure? Is this a linear non-threshold relationship between exposure and health effects?

When we evaluate the arguments of non-scientists, websites, media figures, and pseudoscience publications, a pattern emerges of extrapolation that is not justified from the evidence. Mercury in flu vaccines are present at a small fraction of the dose that is known to cause deterministic health effects. Squalene is found at higher doses in the human liver than in vaccines. And fluoride is only dangerous when it’s at 5-10 times higher levels than are found in drinking water in the western world.
