FROM THE OFFICERS The President's
Message Maintaining our tradition, in this my first message as
Accelerator Section President, I’d like to welcome the new officers of the
Section who were elected last spring and inducted into office at the 55th
Annual Meeting of the Health Physics Society (HPS) in Salt Lake City, Utah.
The new President-Elect is Rich Brey, a faculty member at The President Elect’s
Message As an academic
starting a new semester, and coincidentally starting the job of
President-Elect of the Accelerator Section of
the Health Physics Society, I find my-self somewhat redundantly
providing definitions and as this is the flavor for the month it would be
good to remind ourselves what we mean by an Accelerator Health
Physicists. The Accelerator Sections
web site offers a good definition: An accelerator health physicist is a
radiation safety professional who focuses on the radiation physics and/or
worker protection (operational health physics) aspects of particle
accelerator operations. At large facilities, such as the high-energy
accelerators at many national laboratories, radiation physicists may design
shielding, prepare accelerator operation safety envelopes, monitor
configuration control and perform radiation safety system checks, conduct
original research, and develop or use radiation transport computer codes… The Past President's
Message When was the last time you looked at the Accelerator Section website? If it’s been some time, you may be in for a surprise. Take a look now (http://hpschapters.org/sections/accelerator/) and you’ll see what I mean.
The first thing you may notice is the prominent announcement on the homepage that our former colleague Lutz Moritz was named to the Health Physics Society’s Honor Roll. Lutz is one of the first to receive this prestigious award, which posthumously honors society members who significantly contributed to the profession of health physics during their careers, but who were not otherwise honored by the society during their lifetimes. Follow the link on the homepage to see the photo of Lutz’s son, Dr. Orson Moritz, accepting his father’s award from HPS Past President Dick Toohey. The Editor’s Message In addition to the
usual updates from the Accelerator Section Board members, this issue includes
a couple of articles from people outside the usual accelerator radiation
safety community. The first is from Alan
Wells on a device (of his invention) that supplements accelerator
transmutation of high-level nuclear waste.
The second is from Richard Jones of the American Institute of Physics
on a US Department of Energy report titled “Accelerators for America’s Future.” These articles are certainly a departure
from accelerator radiation safety information you normally find here, but I
hope you will find them interesting and informative. If you care to comment on them or have
similar articles you’d like to see in the newsletter, please (please!) don’t
hesitate to contact me. |

Solving the “Impossible” Million Year Requirement for Nuclear Waste Disposal The Blue Ribbon
Committee for nuclear wastes considers it impossible to guarantee isolation of
nuclear wastes for the one million years[1]
needed for the wastes to decay away, and they are right. Neucon Technology of “Accelerators for America’s Future” Reprinted from FYI: The American Institute of Physics Bulletin of Science Policy News with the permission of the author For optimizing knowledge-based resources in science and technology, and for sustaining an environment for new and revitalized industries and the well-paying jobs they bring, a beam of particles is a very useful tool.”- Department of Energy: “Accelerators for America’s Future” Approximately one year ago the Department of Energy’s Office of High Energy Physics held a well-attended one-day symposium followed by a series of workshops to review “the challenges and opportunities for developing and deploying accelerators to meet national needs.” Earlier this summer DOE released a 100-page report entitled “Accelerators for America’s Future” that presents the findings of the five workshops in key application areas.

[1] The one million year waste isolation period was established by the National Academy of Science and is embodied in the Nuclear Waste Policy Act (NWPA). The uncertainty of natural processes (ice ages, volcanic activity) is small for a 10,000 year period but becomes large for one million years. Thus even though calculations can show that repository leakage and hazard to people would be small over a million years, leakage might become large if a natural event breaches the repository and it is not certain that this would not occur.
