X-Message-Number: 32116 From: Date: Sat, 31 Oct 2009 12:45:50 EDT Subject: Re: Radiation Dr. Bernard Cohen of the U. of Chicago (now Pittsburg) has spent decades studying the effect of varying levels of background radiation on health and lifespan. The bottom line, to the dismay of the anti-nukes, is that radiation is good. The hypothesis is that hormiosis (sp?), the stimulation of the immune system by small amounts of toxins or other insults, makes it better able to fight off real challenges. See _http://www.jpands.org/hacienda/article50.html_ (http://www.jpands.org/hacienda/article50.html) or just Google Bernard cohen radiation. Note there are two theories of radiation damage. One says if 1000 rems kills everyone then 1 rem will kill one in a thousand and .1 rem one in 10,000. This is the linear theory. The other is the old "The dose makes the poison", and says if drinking 10 liters of water at a sitting kills you (and it probably does) then drinking one liter -- is good for you and keeps you from dying of thirst. And there is probably no damage at all from .1 rem of radiation. This is the threshold theory -- below a certain amount there is no harm and maybe a benefit. The truth has never been proved. Twenty or thirty years ago there was an experiment with thousands of mice at low levels of radiation, and trying to autopsy jillions of them for tumors, but it was a debacle and never completed. All we know is Cohen's work that consistently shows people exposed to more background radiation live longer and have less cancer. E.g. we in the Rocky Mountain States, being a mile closer to the Sun and cosmic radiation (i.e. a mile less thick atmosphere to absorb radiation) and near many deposits of uranium etc., get more (twice?) the radiation of those at sea level, and we live longer and have less cancer. I don't recall the exact numbers; haven't looked at it in years. Alan Mole In a message dated 10/31/2009 3:01:21 A.M.

If generally available data produces some sort of result this may be sufficient to get funding for a more precise one. However to be really effective such a study would need to be limited to long term residents -- most people "relocate" ie move house very frequently these days. Also, of course, other causes of death such as accident need to be removed. -- Sincerely, John de Rivaz: http://John.deRivaz.com for websites including Cryonics Europe, Longevity Report, The Venturists, Porthtowan, Alec Harley Reeves - inventor, Arthur Bowker - potter, de Rivaz genealogy, Nomad .. and more ----- Original Message ----- From: CryoNet To: Sent: Friday, October 30, 2009 9:00 AM Subject: CryoNet #32112 - #32113 Content-Type: text/html; charset="US-ASCII" [ AUTOMATICALLY SKIPPING HTML ENCODING! ] Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=32116
