Thank You Jay for putting up Abe Petkau's Picture. When I met him first, he did not want to have a photo taken of him and we met in a high up Hotel in Winnipeg, with doors safely secured and he was afraid of anybody to spy-out what we were talking about.
So now it may be said here I hope.

Sadly I just find the notice of Abe Petkau having passed away, even before the Fukushima-Triple Core-Meltdown, which would certainly have been extremely interesting to discuss with him. I had the privilege to meet and talk to him in private and found he was a very life-concerned Medical Researcher. In fact I enjoyed the opportunity to meet him twice for a long talk about organic-bound low-level Radio-activity of Tritium and Radio-Carbon (3T & 14C), which our Swiss Friend and Author of the book about ”The Petkau-Effect” mediated for me in 1997.
A.P. was concerned, that the IAEA in 1986 had not taken his advice to classify the low-energy beta-radiation as much more dangerous than the current estimations still regard. More-so, envisioning the lack of possibilities to separate and retain Tritium safely and permanently will be of greatest Significance when ‘The Solar-Fusion’ is to be ignited here on Earth. They are intending to use many fold the former Global Tritium-Content of all surface-waters in one engine-block to create the Heat of a Million-Degree Solar-Fusion with the accepted Risk of Bio-Cid as Threatened Side-Effect as yet in lack of any metal that could tolerate more than 5000ᵒ of Heat! A Melt-Down or Explosion of the envisioned Containment (Fusion-Reactor) would be the result and the Global Surface-Waters would again be overburdened (and probably much more than in the Thermo-Nuclear Atmospheric Test-Phase in the middle of last century).
So the Tritium-Problem has had to be recalculated and is now "reconsidered as been solved", so that the Official Monitoring with the very expensive Low-Level Measuring Laboratories could globally be saved.
Fact is, that the Problem from Material-, Corrosion- and Permeation-Point of view has had to be put aside as un-solved, as Problem presently without a solution possible, because there is for Tritium as yet No Permanent Retention Possible and No Safe Depository Available on this Planet. So it was accepted as such and Not Be Necessary.
And the Global Waters would by necessity have to be legally allowed to be progressively polluted with this non-retainable waterborne Tritium.
These Facts had only been possible to show by Controlled Measuring in Special "Cleanest-Room-Laboratories". After Chernobyl and the following measurements there were tendencies globally for abolishing and legally closing them after 'declaring them globally for unnecessary', too expensive and anyway inefficient.
The large Refuelling Plants at Tokaimura, Livermore, Sellafield and LaHague and in Russia anyway had the highest permissions to set free "All Volatiles" as necessary, since No Technology had been possible to be developed for Retaining or Retrieving, for Permanent Storage or Safe Separation.
So the Low-Level Beta-Problem-Calculations had to be called as acceptable and safe. Disregarding - and that was the point which made Abe Petkau so sad about the results of his former work - disregarding the radioactivity carried as bound in the organic Material disturbing the Metabolism of the Lipid-Membranes of all living Organisms, of all developing Life and of all Organic Processes interchanging with progressively unsafe Surface Waters.

The actual measurements now can only show tendencies of acute alterations, as
the actual background-radiation in the Laboratory has to be taken for comparison and be subtracted from the measurement. So the true deviation might only be shown by comparing deep 'old' ground-waters with the present rain-waters, and the spontaneous Radiolysis with Free Radical-Formation is called for Ozone-Effects. Or "increased Draught because of Pan-Evaporation".
Abram Petkau answered to me, when I asked why no proper large-scale detailed investigations about the effects of organic-bound radiation had been done, that the "Big Atomic Family" initially even had the vision to try with a System cooled by a Solution of Protein and Fat moderating the Reactor.
"What happened to the idea ?" I asked.
"The Moment they switched it on - it all burnt up with big black smoke as ignited organics, and that was the end of the system. But this was never published."
