medical science - Is there no risk-free level of second hand smoke? - Skeptics
..an interesting read..Here are a few excerpts:
Living is full of risk, the only away to avoid all risk is to cease to exist. The Surgeon General's warning about there being no risk-free level of secondhand smoke exposure is misleading, and ignores hundreds of years of toxicology that show that all poisons have some minor exposure level that is not harmful.
So while it is true that there is no risk free exposure to SHS, there is also no where on earth that you can be free of natural occurring carcinogens. Report of the United Nations Scientific Committee on the Effects of Atomic Radiation to the General Assembly
11 . Everyone is exposed to natural radiation. The natural sources of radiation are cosmic rays and naturally occurring radioactive substances existing in the Earth itself and inside the human body. A significant contribution to natural exposure of humans is due to radon gas, which emanates from the soil and may concentrate in dwellings.Since radiation is everywhere, the Surgeon General could just as well had said,
There is NO risk free level of living on earth.
The father of toxicology, Paracelsus said, "All things are poison, and nothing is without poison; only the dose permits something not to be poisonous."
A real world example might be in order:
If you count deaths at all ages, DHMO was responsible for an estimated 3,880 deaths in the USA, more than the estimated deaths each year due to secondhand smoke (3,400 per year).The above statements are all 100% true, but extremely misleading. If you are currently attempting to protect yourself from the dangers of Dihydrogen Monoxide, you will likely be issued a Darwin Award. This dangerous chemical is water.
The EPA says we shouldn't be concerned about lead in our drinking water that is below an action level, but the Surgeon General wants to repeatedly warn us that NO risk free level of second-hand smoke exists. Lead is a carcinogen whether it is in your drinking water, or in your smoke. It seems foolish to warn us about exposure from one source while ignoring the other.
Your food isn't even safe. Bananas because of their high potassium content, contain more [radioactive Potassium] than other fruit. Eating 2 bananas a day for a year would expose you to more radiation than you would get from a single chest x-ray (about 10 mrem).
