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

I don't have time to read all the published literature.  The Smith and Doll
study on the early British radiologists gives me confidence, as does the
statement by Lauriston Taylor in 1980 that no one was identifiable injured
when working within the guidelines of the first (1934) ICRP standard.

The published literature would strongly suggest that limit did not protect
radiologists. A key reference would be Warren in JAMA in, I think, 1954. As
someone who works with & is married to a radiologist, I find the character
assassination quite entertaining. A great deal of harmless entertainment can
be found in following the substantial literature on radiologist longevity,
especially the repartee in the ensuing correspondence.

Cheers
Jeremy

Victor et al.

For "the new radiation safety standard," I recommend reverting to the ICRP
standard that was accepted in the early 1930s; i.e. use the concept of a
safe tolerance dose of 0.2 Roentgen/day, which is equivalent to about 680
mGy/year.  It provided adequate protection to the radiologists for at least
two decades and would still be satisfactory today for radiation workers.
The total-body acute dose limit for radiologists (radiation workers) should
be 150 mGy.   

There was no scientific justification to change the radiation protection
concept in the mid-1950s.  That was done for the political purpose of
stopping the development and testing of nuclear weapons.

I volunteer to help solve this problem.

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.

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
