RE: "Limit to Survival - Effect of Radiation
As a counter argument, I could say that since we do not have stresses like
malnutrition, malaria, smallpox, typhoid, etc., we do like longer. Of
course, less radiation through regulations have also increased our life
span, which has been going up since the end of the 19th century. Check out
the facts.
Yes, there are lies, damn lies and statistics.

Subject: "Limit to Survival - Effect of Radiation
Pertinent to radiation safety (topic) is, A, how prove increased longevity,
then, B, how implement supplemental radiation in apparently deficient areas
like the Gulf sates - as proposed by Cameron in Is Radiation an Essential
Trace Energy? http://www.aps.org/units/fps/oct01/a5oct01.html.
My experience as a personal physician and amateur social anthropologist
would
seem to contradict Peter Parson's premise that, "In modern human
populations,
selection for stress resistance is less intense than in earlier times."
(below)
Natural selection is by mortality rates. Persistent "stress", via adrenalin
(fight or flight from anger or fear) 1, shortens clotting time (as in
coronary
thrombosis - myocardial infarct or cerebral thrombosis - stroke), 2,
stimulates arrythmias (400,000 USA deaths yearly, about same as total cancer
deaths) and 3, may constrict normal coronaries (voodoo effect). "In earlier
times" there were no lights at night, no watches for time consciousness, no
radio, TV, ads, driving, etc to give such persisting attentiveness, tension
and stress as we have now. My most frquenly prescribed medication is an
adrenalin blocker and decades ago it was tranquilizers.
These changed causes of death may benefit from radiation hormesis by impoved
ciculation. That lessened (0.76) death rate of 28,872 nuclear shipyard
workers exposed to 0.5 cSv extra (about the better longevity of mountain
state
residents) compared with 32,510 coworkers not exposed, suggests a deficiency
disease. A mechanism is suggested by the better healing of gangrene and
bursitis with 75 cSv doses of X-ray in the 1930s, before antibiotics and
cortisone. Radiation gives blood vessel dilation with better oxygenation and
nutrition of the tissues. Stress and adrenalin have the opposite effect -
constriction of skin circulation.
For longevity, we should prove with placebo controlled, double blind
studies,
whether fewer cancers and heart atacks, lower c-reactive protein and better
longevity does come with supplemental radiation.
