"Medical Benefits of Low Dose Radiation," November 15, 2000 |
Preliminary Program
Symposium Summary Report, by Dr. Jerry Cuttler
Tutorial: The
Biological Imperative: Low-Dose Radiation Stimulation, Ron Mitchel, Ph.D., and Doug Boreham, Ph.D.,
Health Canada and McMaster University, Hamilton ON CANADA, "...experimental evidence indicates that the basic assumptions
[of radiation damage] break down at low doses and dose rates, seriously challenging
current radiation protection practices as well as identifying biological responses that
can be exploited for medical therapy... Recent advances in molecular and cellular biology
have placed such observations on a secure scientific footing.
This tutorial will review the biology of low dose/low dose rate
ionizing radiation exposure and provide examples of the consequences in cells and in
animals. Our current understanding of radiobiology, and the actual experimental
observations, will be tested against the widely held assumptions about radiation exposure."

None of the predictions of the LNT hypothesis, as it applies to cancer risk from
low or chronic doses of low LET radiation, are supported by the data in human or rodent
cells. The limited data in animals also indicates that the observed responses are not
consistent with the hypothesis. The protective responses observed in mammalian cells and
in animals are consistent with those seen in lower eukaryotes, including yeast, indicating
that they are evolutionarily conserved and lending credence to the idea that such
responses are the normal and expected consequences of low dose exposures.
Scientific advancement depends upon the testing of hypotheses.
When the data do not support the hypothesis being tested, that hypothesis must be rejected
and replaced with a new testable hypothesis. Since, at low doses and dose rates,
there are no data in the literature that support the LNT hypothesis for cancer risk, and
considerable evidence contradicting it, including the evidence given above, then
this hypothesis must therefore be rejected.
It is time for a new risk based approach to radiation
protection, firmly linked to the actual biological responses.
Cellular
and Organism Dose-Response: Biopositive (Health Benefit) Effects, Myron Pollycove, M.D., U.S. Nuclear Regulatory Commission, Rockville

"Abstract: The genes in every cell
continuously undergo an immense amount of metabolic damage by reactive oxygen species
(ROS) which is prevented, repaired, and removed by a complex antimutagenic system. Recent
studies document low dose radiation stimulation of many cellular functions, including
antioxidant prevention, enzymatic repair, and immunologic and apoptotic removal of DNA
damage. This homeostatic system is stimulated by a ten, or even a hundredfold
increase in background radiation. Enhanced prevention of gene mutations by the
spatial and temporal differences of ionizing radiation ROS and metabolic ROS is associated
with radiation hormesis: decreased mortality and decreased cancer mortality
observed in populations exposed to low dose radiation. Therapeutic stimulation of the
immune system by low dose body irradiation prevents and removes cancer metastases in mice,
rats, and humans.
Cellular and
molecular changes induced by low versus high dose radiation, Shu-Zheng Liu, Ph.D., MH Radiobiology Research Unit, Norman Bethune University of Medical
Sciences, Changchun, CHINA drliusz@yahoo.com
Abstract: "When one goes down to the lower dose
range, especially with doses below 0.2 Gy, changes of many biological parameters (are) in
the opposite direction to those observed with doses higher than 0.5 Gy... thus resulting
in a U- or J-shaped or an inverted U- or J-shaped curve.
"...data from the authors laboratory
demonstrate the difference in the nature of effects induced by low versus high dose X-rays
at molecular and cellular levels, as well as their implications in the intact
organism."

85 abstracts demonstrate consistent research
results and literature reviews that indicates that low-dose ionizing radiation in whole

Radon: Health Risks
and/or Benefits? The View from Europe, by Prof. Dr. Klaus Becker,
V. P., Radiation, Science & Health, Berlin, Germany, prof.dr.klaus.becker@t-online.de
"Radon
may be one of mankinds oldest therapies: Close to the source with the
highest radon concentration in Gastein/Austria, 5.000-6.000 y old votive offerings have
been found: the ancient Romans and other old civilizations appreciated radon spas; and in
Japan, the springs on Misasa, with up to 160.000 Bq/l of radon, have been used for 800
years. Currently about 75.000 patients annually are treated in German or Austrian
radon spas and many more in other countries, in particular in Russia mostly for
painful joint or backbone diseases such as rheumatic arthritis and spondilytis ankylosans
(Morbus Bechterew), either by inhaling high radon concentrations (in the Bad Gastein
Heilstollen", for example, about 170.000 Bq/m³, or more than 1000 times of the
current EPA residential radon limits), by drinking, or by bathing in radon water. The
expenses (e. g. in Bad Gastein about $ 500 for 10 h) are mostly paid by the health
insurance systems. Even in the more radiophobic USA, the Free Enterprise
Health Mine" has been operating successfully for half a century.
"Many clinical studies, some of them
randomized double-blind studies, clearly demonstrated the superior effect of radon in
comparison with an otherwise identical treatment lasting for several months after the end
of the treatment."
Low
Dose Radon as Alternative Therapy for Chronic Illness, Barbra
Erickson, Medical Anthropologist, University of Nevada, Reno,
Nevada (USA), WONUC Conference, Versailles, FRANCE June 1999
Abstract: "This paper addresses the possibility that the LNT model
may not be applicable for low doses of radon, and that low doses of radon may in fact be
beneficial for certain chronic illnesses. There are growing numbers of studies
indicating an inverse relationship between cancer occurence and low dose environmental
radon exposure, as well as numerous studies examining the therapeutic effects of low dose
radiation. This protective or beneficial effect, called hormesis, has gained recognition
by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR). A
large body of anecdotal evidence in support of hormesis exists, in the form of thousands
of people who annually use radon spas worldwide... I argue that if a chance exists
that chronically ill people may be helped through treatment with low dose radon, then
scientific examination of the radon health mines in Montana should be carried out.
The fact that much of the supporting evidence is anecdotal should not be a cause for
dismissal; on the contrary, that so much anecdotal evidence exists should provide greater
incentive for research."
Challenges in providing low-dose irradiation therapy, J.M. Cuttler, Sc.D., Cuttler & Associates Inc., Mississauga, ON, CANADA, jerrycuttler@home.com
Abstract: "Although the existence of beneficial
health effects following low radiation doses has been known for a century, a controversy
rages among scientists regarding this subject. This seems to be due largely to political,
social and economic issues... The medical community could resolve this health concern by
starting to provide low-dose irradiation (LDI) therapy, which would help many cancer
patients cope with their illnesses at very little risk. Slow progress is being made in
Japan and Europe, but there are many barriers everywhere to the introduction of this
therapy. The nuclear community should help physicians overcome these barriers. Cancer
patients and their support groups, by urging hospitals to offer LDI therapy, may be the
key."

"Abstract: Successful clinical
trials of low dose irradiation therapy for curing cancer were carried out in the USA in
the 1970s and, more recently, in Japan and France. A cure of colon cancer and a case study
of the successful control of a cancer of the blood following this low-dose therapy are
reported. The prompt, beneficial response of the patients blood data to the
radiation exposures supports the notion of radiation hormesis in humans. Widespread
application of low dose therapy would help many cancer patients and could help to correct
misconceptions and resolve the controversy about the biological effects of low doses of
ionizing radiation."
Ionizing Radiation and Radioactivity in the 20th
Century, Zbigniew Jaworowski, Ph.D., Central

Conference on Radiation and its role in Diagnosis and Treatment. FICR - 2000. Tehran, IRAN
October 18-20, 2000.
"After ionizing radiation and radioactivity were discovered at the end of the
19th century their social status has oscillated between enthusiastic acceptance
and rejection. This was in concurrence with recognition of their three basic aspects: 1)
usefulness for medical applications and for technical and scientific aims; 2) beneficial
effects of their low levels; and 3) harmful effects of high levels. In the first part of
the 20th century the acceptance prevailed, in the second the rejection. The
change of the public mood, that occurred rather abruptly after the World War II, was not
due to discovery of some new danger of radiation, but was caused by political and social
reasons, not related to real radiation effects."
Its Time to Tell
the Truth About the Health Benefits of Low-Dose Radiation, by James
Muckerheide, Radiation, Science, and Health, Needham MA; Center for Nuclear
Technology and Society at Worcester Polytechnic Institute, Worcester MA; Mass. State
Nuclear Engineer, Framingham, MA rad_sci_health@comcast.net.
"Low-dose radiation is documented to be beneficial for human health but,
for political reasons, radiation is assumed to be harmful at any dose.
Radiation-protection scientists, and others, who cover up the data that contradict present
policy should be investigated for misconduct.
"Low-dose radiation has been shown to enhance
biological responses for immune systems, enzymatic repair, physiological functions, and
the removal of cellular damage, including prevention and removal of cancers and other
diseases. Research on low-level radiation has also shown it to have no adverse effects.
Yet, current radiation protection policy and practice fail to consider these valid data,
instead relying on data that are poor, ambiguous, misrepresented, and manipulated.
"With no regard for the cost to scientific truth, and to
taxpayers, radiation policy is based on the linear no-threshold (LNT) concept, that holds
that radiation at any levels above zero is deleterious. In the LNT view, the known
damaging effects of high-dose radiation are linearly extrapolated down the dose scale. LNT
contradicts the scientific evidence, which shows that there is a radiation threshold,
below which there is no harm and, in fact, there is benefit for human health, a process
known as hormesis, which is normal biological response to all stressors. In defiance of
this evidence, radiation-protection policy relies on falsification of the actual science
research and reporting. Such malfeasance warrants scientific misconduct investigations for
the results promulgated by some radiation protection-funded scientists."
Applying
the Data: In Science, Law, and Public Policy,
Theodore Rockwell, Sc.D., Founding Officer: Radiation, Science, and Health, Inc.
and MPR Associates, Inc.; Technical Director, US Naval Nuclear Program, US AEC-retired. tedrock@cpcug.org
The credible science shows that while
high doses of radiation can damage living organisms, low doses stimulate the bodys
defenses to promote many important beneficial health effects and medical applications.
More aggressive actions are planned or under way; and more are being proposed: to apply
the science to challenge, in court if necessary, EPA's proposed rule on 'radionuclides in
water;' to challenge DOEs false reports on radiation health effects in workers, and NRC on
the false NCRP SC-1 report; to consider filing allegations of 'scientific misconduct' in
the more egregious cases of manipulation and misrepresentation of the data that claim
support for the LNT; and to apply the science to expand LDR medical applications to treat
cancer, infection, inflammation, and other conditions, including diabetes, AIDS, wound
healing, with appropriate research and clinical trials. |
