The Petkau effect(extended low dose radiation dangerous to cellural membranes)

The Petkau effect is an early counterexample to linear-effect assumptions usually made about radiation exposure. It was found by Dr. Abram Petkau at the Atomic Energy of Canada Whiteshell Nuclear Research Establishment, Manitoba and published in Health Physics March 1972. Petkau had been measuring, in the usual way, the dose that would rupture a particular cell membrane. He found that 3500 rads delivered in 2¼ hours (26 rad/min) would do it. Then, almost by chance, he tried again with much weaker radiation and found that 0.7 rads delivered in 11½ hours (1 millirad/min) would also destroy the membrane. This was counter to the prevailing assumption of a linear relationship between total dose or dose rate and the consequences.[1] The radiation was of ionising nature, and produced negative oxygen ions. Those ions were more damaging to the membrane in lower concentrations than higher (a somewhat counterintuitive result in itself) because in the latter, they more readily recombine with each other instead of interfering with the membrane. The ion concentration directly correlated with the radiation dose rate and the composition had nonmonotonic consequences.

A long term exposure of

A long term exposure of extremely low radiation (i.e., one-ten millionth of a rad per minute) was found to be 100 BILLION times MORE lethal than a short term exposure to exceedingly high level radiation (i.e., 10,000 rads per minute). As it turns out, Petkau discovered that at exceedingly high radiation levels, the abundant free radicals generated in tissues tended to cancel each other out before they could do cellular damage. But at extremely low levels of radiation, these same free radicals - produced in minuscule quantities - remain unchecked. And any steady stream of unchecked free-radicals will efficiently and lethally cleave lipid cellular membranes like a hot knife slicing through butter once they overwhelm and exhaust cellular antioxidant defenses. This dramatically illustrates the non-linear aspects of dose (rads) to lethality. Most scientists specializing in the field of nuclear medicine are unaware of this fact. And most think strictly in terms of genetic damage, while the above presents its lethal affects upon cell membranes and only secondarily to the genetic core.

So, what Petkau proves is that prolonged low doses

may destroy or mutate dna and cells and hence may cause cancer, leukemia, thyroid cancer, birth defects, spontaneous abortions and death FASTER than higher more intense doses of shorter duration.

The way I read the Petkau research is that SMALLER overall doses or exposure, cumulatively, are WORSE than higher doses.

The wiki page explains it much better than I can.

I use the analogy of the balloon and the pin or hammer: you can hit a balloon gently with a hammer and no pop because the molecules of the metal cannot penetrate the balloon, whereas a needle using much smaller amounts of metal will stick right through the balloon and destroy it. The same kind of thing with cells and big dose vs. low dose.

Same analogy sort of with second hand smoke: smaller particles more broken down in minuter sizes penetrate the lung cells easier.

A scientist friend explaining the Perkau effect used the "yelling fire in a theater" analogy: people can proceed through a door more easily and faster one at a time, but if they bunch up they get stuck and fewer get through quickly and some may not get through at all.

(Not to mention the synergistic negative effect when radiation combines with other carcinogens and mutagens in the environment like coal pollution, auto emissions, chemicals and insecticides and herbicides, etc.

I sometimes wonder if they WANT to increase the death rates to reduce the population of the world to make the world's people more manageable and controllable (especially if we are all getting sick and will also buy more meds and need more meds).

Petkau's effect may seem counterintuitive and Petkau thought it was too - he was surprised but this "low dose" over prolonged exposure may simply permeate our whole bodies wreaking havoc in our dna and organs and especially it children and infants and fetuses it can cause leukemia, birth defects and death.

It is important to know these things.

Thanks for sharing it. Petkau. Remember that name when there are unexplained illnesses and pandemics in the coming years or even months (especially in Japan where TEPKO and the government keep insisting the "low" doses are not yet harmful)

But its just our

But its just our imagination. Right?
