RJ Barish/Radsafe,
Looks like some good papers to read on HP/Aviation/Exposure etc.
Cosmic Rays, other exposure mechanisms are probably time-varying, so it might
be good to continue doing measurements, modeling, theory in these areas of
research. Have at it, JJS, RJ Bartish others.

PS eRHIC etc. accelerators to be built over the next 20 years. Any other
USA, world accelerators to be built over this time frame????

Included here is most of a posting I sent to RADSAFE sixteen months ago:
These are some of my papers on the subject, including three in Health
Physics:
R.J. Barish. Health Physics Concerns in Commercial Aviation. Health Phys.

1326-1330 (2004)
R.J. Barish. Radiation Risk from Airline Travel. J. Am. Coll. Radiol. 1:

Health Phys. 96: 456-464 (2009)
R.J. Barish and S. Dilchert. Human Resource Responsibilities: Frequent
Flier Radiation Exposure. Employ Respons Rights J. 22: 361-369 (2010)
(The last paper specifically addresses the issue of frequent flyer
exposures and potential employer obligations to those workers.)
and there’s also my book:
R.J. Barish. The Invisible Passenger: Radiation Risks for People Who Fly,
2nd Edition, Advanced Medical Publishing (Madison, WI: 2008) ISBN:
1-883526-13-2, ISBN13 978-1-883526-13-2
To be honest, after seeing the European Union require mandatory dose
assessment for flight crew in 1990, while the FAA still to this date makes the
subject a voluntary educational topic for airline management to either teach
or ignore, I’ve just about given up on any further interest in the topic.
CDC-NIOSH has been performing epidemiological studies on groups of female
flight attendants looking for increased mortality from breast cancer and
melanoma. Their results on a cohort of more than 11,000 women show “ no
evidence of increased breast cancer or melanoma mortality.” Pinkerton LE, Waters
MA, Hein MJ, Zivkovich Z, Schubauer-Berigan MK, Grajewski B.
Cause-specific mortality among a cohort of U.S. flight attendants. Am J Ind Med. 2012
Jan;55(1):25-36.
So unless one is interested in using these thousands of low-dose (but
definitely measurable) exposures of hundreds of thousands of flight crew
members to advance the idea that exposures in this range refute the LNT
hypothesis, I don’t see much more coming out that will be useful.
Perhaps the added exposures discussed in detail by Shonka and Bramlett
(SPE, SNE, SGE) in their January Health Phys paper make the failure to note
any increase in cancer mortality by CDC even more supportive of the possible
failure of LNT.
