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

[JERRY CUTTLER]

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
