More progress!

[Muckerheide <muckerheide@MEDIAONE.NET>]

Radsafers,



The link below provides more hard evidence of the progress we are making!



Consider that we must also actively engage the matter posed here:

What are the science policy, and regulatory policy, effects of the

demonstration of hormesis!  Research scientists directing work to the LDR

medical applications, and the issues of optimizing exposures for beneficial

effects.  Program policies should be directed to develop medical research

funding, and away from "radiation protection" source funding, etc.

(Note: You can link to the full paper!)



Answers to the two questions in the abstract:



a) There can be, but only at the 'higher' levels of the LARGE hormetic dose

range.  (When we see the data at many small dose increments of background

radiation, and apply chronic or highly fractionated exposures, we will see

more of a "plateau" than a "parabola"  --  'J-' or 'U-shaped' may be in

block letters. :-) 



b) A low to moderate level of toxicants (doses) will provide full benefits,

and additional sources will have no effect (like taking vitamins - if you

have enough, more won't "help," but "more" will assure that you have enough.

[Note this is also why "hormesis" is often not seen in experimental results:

especially with SPF and other optimally kept animals that are not challenged

- they have no "better" to get, so mean life is not different.  But give

both populations infection or mutagens/carcinogens, or inject tumors, you

will more likely see a difference!]
