[ RadSafe ] Article by Vincent Giuliano on "Radiation Hormesis"

´Dear Rick:

So nice to read your message.  Thanks very much!  It seems you are all very
well and enjoy the family near and far.  I wish the distance would not  be
so great and we could see each other from time to time.  I don't know when I
may have the chance to come to the West coast - but if I do I surely make it
to see you all again. 

Jeannine and I are in Wengen since before Christmas and had a nice holiday
and New Year's eve.  Dominik and Christophe with family came up to spend
some time with us - lots of fun especially with the grand kids.  Manouk,
soon 16 years old, traveled to Australia last week to join a school there
for 8 months. It is an exchange program and a great challenge for her.  We
are all anxiously waiting how she is going to master the new life.  

The end of February I am back at NIH for a week and then I continue to visit
BNL for a week.  We plan to come to some concrete suggestion for the next
workshop.  Ed Azzam and Roger Howell are ready to meet with me.  By the way,
I think you know that the Medical  Department at BNL does not exist anymore.
There was a small get-together at the end of September to "celebrate" the
fusion of the old Medical and Biology Departments to the new Department of
Biological Sciences.  It was a historical moment - and I hope it will lead
into the right direction.  To me, the exclusion of medical research from
having a foothold in the larger translational and interdisciplinary research
environment of the lab may curtail the range of medical progress. 

Give my love to all of your family, especially Chris and let's keep up
trying for a reunion.
Kindest,
Ludwig

Good Morning,

The evidence for hormesis is certainly there.  I too believe that LNT is no
longer a viable basis for radiation safety.  Being an ex-regulator, for me
the next big question is placing some numerical values on radiation safety
standards.  Given that X Gy of dose will not cause any harm, should that be
the new radiation safety standard?  This brings as least two questions to
mind: 1) Given biological variability, what is a safe upper limit? and 2)
How does the new standard work for different types of radiation, rates
(gy/y, gy/hr?), mode of delivery?  We also need to look at a new unit as the
Sievert and REM were both pegged to probability of death by cancer.  So, if
say 1 cGy of gamma radiation has no risk of cancer, then the risk based dose
is zero (0 cSv).  Suppose there is a region where there is some protective
benefit mixed with some chance of harm?  A fine kettle of fish. The reason I
ask is that the next step is to petition the NRC for a rule change.  The
bigger question is what kind of rule change?  With this is mind, I would
propose an an hoc committee to work on this problem.  Any takers?  If so,
please e-mail me.

Victor Anderson, CHP

Hi all,

I came across an interesting 7 September 2012 article on the web by

Vincent Giuliano titled "Radiation Hormesis."  The link for the article

follows:

http://www.anti-agingfirewalls.com/2012/09/07/radiation-hormesis/

I thought some of you may like to know about the article.

Best wishes,

Bobby
