AW: AW: RE: AW: [ RadSafe ] DNA Damage and Oxydative Processes

Jerry:

As you say, it's a micro-'review' from sources like:

* Caufield C, Multiple Exposures, Chronicles of the Radiation Age. Secker & Warburg, London, 1989

* Jones C G, A review of the history of U.S. radiation protection regulations, recommendations, and standards. Health Physics 88#2(2005)105-124

* Kathren R L, Pathway to a paradigm: the linear nonthreshold dose-response model in historical context: The American Academy of Health Physics 1995 Radiological Centennial Hartman Oration. Health Physics 70#5(1996)621-635

* Kathren R L, Historical development of radiation measurements and protection. in: Brodsky A, ed., Handbook of Radiation Measurements and Protection, Vol I, CRC Press, Boca Raton, 1985(2nd), p. 13-52

* Kathren R L, Early X-ray protection in the United States. Health Physics 8(1962)503-511

* Meinhold C B, Lauriston S. Taylor Lecture: The evolution of radiation protection from erythema to genetic risks to risks of cancer to ... ? Health Physics 87#3(2004)240-248

* Sinclair W K, Radiation protection recommendations on dose limits: the role of the NCRP and the ICRP and future developments. Int. J. Radiation Oncology Biol. Phys. 31#2(1995)387-392

* Taylor L S, Radiation Protection Standards. CRC Monoscience Series, The Chemical Rubber Co. and Butterworths, London1971

Not all of these being as enlightening (for me) as Kathren's work, you or others may find them useful in one or the other way.

Regarding LNT humbug spreading from radiation I can add another absurdity: Having previously (of course after consulting the proper textbooks) treated myself occasionally for minor ailments with phytotherapeutic drugs - freely and cheaply available at the pharmacists - over the years in several instances I tried in vain to get them. This, because someone had demonstrated in rats at dosages orders of magnitude higher than at therapeutic concentrations that cancer incidence increased beyond the spontaneous level. LNT addiction in our pharmacological regulations invariably resulted in the withdrawal of their accreditation and hence in a ban on their sale.

What Paracelsus obviously can no more achieve, time will. If indeed LNT is fiction, then thresholds or even hormesis will prevail, perhaps only after Max Planck's adage concerning the prerequisites of paradigm shifts has been proven true once more. Otherwise we should be grateful to BEIR VII.

Rainer,
    Again, you have presented an excellent and insightful review on how we have degenerated into the current state of affairs. ....

Soon, the LNT idiocy spread to chemical substances (DDT, PCBs, dioxin, asbestos, carcinogens, etc. etc.).
Several laws (CERCLA, TOSCA, etc),were enacted in the USA & elsewhere legitimizing the idea that "any is too much".
Now, it seems unlikely that we can ever return to rationality.
Paracelsus--- where are you now that we really need you?
