The enclosed National Press Club Conference statement by Dr. Arjun Makhjjni, of the p C/)
Institute for Energy and Environmental Research, Takoma Park, MD - and the Associated Press release by David Gram, coverng the meeting that took place last week in Montpelier - have been, along with BEIR VII, the sources for the statements I make below. I quote from them to support my comments.
Not up for considerationare issues rangingfrom the possibilityand consequences of a terroristattack on the plant - to the - wisdom of generatinghighly radioactivewaste for an extra 20 years when the federalgovernment has yet to open a site to dispose of it.
The above directly concerns the incarceration of radioactive isotopes that create havoc in the biosphere. Only if hermetically isolated for tens of thousands of years will these unstable isotopes be eligible to rejoin the vastly more numerous stable elements of which oceans and earth crust are made or else the background radiation will be too much for most living things.
Other quotes from the article:
Richard Emch, the NRC's environmentalproject managerfor the Vermont Yankee review, repeatedlysaid the agency was looking for 'new and significantinformation" relatingto the safety of Vermont Yankee's electrical, mechanical and othersystems, and environmentalimpacts, for example, to fish species in the ConnecticutRiver.
Rep. Sarah Edwards,P-Brattleboro,saidthe failure of the federalgovemment to come up with a long-promisedsite for high-level waste was a new development since Vermont Yankee was last up for license review in 1972. "isnTthis new and significant information?"she asked.
In an interview,NRC spokesman Neil Sheehan said if Vermont tried to block the license extension, it could risk litigationbecause federal law puts the NRC solely in charge of nuclearplantsafety.
From a statement by Arun Makhijani on the Report Science for the Vulnerable and the Campaignto Include Women, Children and Future Generationsin Environmental Health Standards" Natdonal Press Conference, Washington, DC, 19 October, 2006: In 2005 the Committee to Assess Health Risks from Exposure to Low Levels of Ionizing Radiation(NationalResearch Council of the NationalAcademies) issued a reportthat concluded that women have a 52 percent greaterchance than men of getting cancer
from radiationexposure. Seven years ago, the EnvironmentalProtectionAgency had reachedsimilarconclusions. Yet, much radiationprotectionregulation is still stuck in the past- its "reference-person is a man.
Please see the enclosed Makhijani statement and please review the detailed Institute for Energy and Environmental Research Science for Democratic Action (lEER SDA) newsletter. I gave up my only copy to Mr. Richard Emch, the NRC environmental project manager for the Vermont Yankee review, after the meeting with VT Legislators at the Pavilion Building in Montpelier, Vermont on Tuesday, February 27th. I have sent away for others to distribute at talks in the NorthEast Kingdom of Vermont and to attach to this comment.
My specific concern for this comment period is as follows: The National Research Council of the National Academies report has highly pertinent information about the effect of low level ionizing radiation on women, embryos, fetuses, and children. This information is also found in the BEIR VII report (Biological Effects of Ionizing Radiation, 7th report, issued October 18th, 2006. This information was not given its due by those who wrote the SEIS draft report for the VY relicensing process.
The NRC mission, as Mr. Neil Sheehan and Mr. Emch said, is nuclear plant safety and security. Sheehan stipulated that the NRC has been given the last word by the Federal Government to decide what is safe and what is not safe Inthe area of nuclear safety. If so, the NRC should explain in the report why it can ignore the science that proves that:
- 1. Low level ionizing radiation - radiating over a long period of time in the area it lodges in body tissue - causes cancer and can alter DNA in eggs and embryos.
- 2. Women, embryos, fetuses, toddlers and children are more susceptible to radiation exposure in general. Among the culprits is the low level ionizing radiation from unstable radioactive isotopes such as Strontium 90 and Tritium that are ingested and lodge in the body, in teeth, near bone marrow that builds immunity, and finally near the nucleii of female eggs and embryos.
The following facts are also relevant:
- 1. The off-gassing of nuclear power plants, including the Vermont Yankee, contain these and other radioactive isotopes that fall on the grass, get into milk and plants that humans and other mammals consume. Humans in turn consume the meat from some of those mammals who consumed contaminated plants. We are at the top of the food chain in most incidences. Though low level radiation from isotopes is the worst form of cancer-causing agents, other types of radiation also weaken the mammal's immune system, more specifically the militias of T Cells that can help combat the effects of this ionizing radiation. Human mammals sit in front of computers, televisions, fly in planes, and handle and ingest immune system depleting chemicals. All, over time, affect immune systems. Humans thus become much more likely not to have the T cells needed to combat the effect of ingested-and-lodged, ionizing, radioactive isotopes from the off-gassing of nuclear power plants such as the Vermont Yankee.
-?3-
- 2. The incidence of breast cancer has increased in the last decades to one in every eight women. It is not surprising that this statistic resonates with the more recent statistic that women are 52 percent more likely to contract cancer than men.
- 3. Those who are economically challenged cannot afford organic food and supplemental vitamins and minerals that can boost immune system T cells and control nascent formation of cancerous cells. This fact should be considered in the environmental justice evaluations that are done in NRC Environmental Impact Statements. I would strongly recommend that all economically challenged people -
especially women and children - living in the shadow of nuclear facilities should receive free immune booster supplements and extra allowances for certified organic food and milk, free from chemicals and radioactive isotopes. This should be kept up until 12.5 years have past after the decommissioning that region's reactor.
- 4. The Vermont Yankee does not have state-of-the-art filters in its 300 foot high smoke stack. Even if it did have them, it would still not be able to filter out tritium, a short-lived (half life - 12.5 years) isotope that lodges near the nucleus of cells and radiates the DNA inside. This has been shown to cause aberrations in the DNA that result in miscarriage, deformities and it may be responsible for breast cancer developing during the life of that embryolfetus. I do not have the most recent lEER SDA issue that explains this. Please see Mr. Emch's copy
- 5. If tritium can be somehow precipitated out of the gasses before emission and disposed of appropriately, this must be done. I do not have the lEER SDA issue that talks about this. Please see Mr. Emch's copy. I have tried to Google this but without much success.
Before it is relicensed, the Vermont Yankee should replace its filters with the most modem technology possible and also find a way to take out the tritium and have it isolated from the environment for its half life of 12. 5 years and then some. This is because of the recent discovery of its affinity for the nucleus of the cell where it is able to modify the DNA.
Before it is relicensed, the Vermont Yankee should change its regulation criteria from "Reference Man' to "Reference Woman-Embryo-Fetus-Toddler-Child.
In paragraphs 5 and 6, Makhijani shows that the Connecticut Yankee Atomic Power Company was able to conserve the Reference Man, the young White male, as the abasic underlying document governing the regulations" (Please see #11 (FRG1 1).
The NRC permitted the CY Atomic Power Company to argue that a white male, 20-30 should be the basis for calculation, and that their "regulationsprohibit considering doses to children" despite the fact 'the plain languageof the regulation itself does not restrict the terms 'criticalgroup,' 'individual',or 'human being' to mean any specific age, race, or gender.
I take this to mean that the overall language of the fully written regulation uses non-specific words in talking about one person, people and groups of people but, when it comes to setting the regulation for the standard for acceptable levels of ionizing radiation, its template is age-race-gender specific. Pretty blatant segregation, one might contend. If it is to continue, the tax paying public deserves to hear a full explanation of NRC logic so they can decide whether or not this discrimination should prevail. This is
happening In a democratic country which is known world wide for hard-fought-for civil rights non-violent action victories.
Thank you for considering this comment and for doing all you can to allow as much transparency and independent oversight as needed to assure that the over 100 aging reactors seeking relicensing are safe to live down wind from and are secure from potentially highly-malignant elements such as terrorist attacks on the spent fuel.
Land has been lost to invaders. The U.S. DOE and the U.S. DOD have eliminated land from our nation for tens of thousands of years due to commercial and military development of nuclear power in one form or another.

Healthy from the Start:
Building a Better Basisfor Environmental Health Standards-Starting with Radiation BY ARJUN MAKHIJANI, BRICE SMITH AND MICHAEL C.THORNE' he last half century has seen great progress in environmental health protection. As part of this progress there has been a growing awareness that the focus must be the protection of those most at risk. The protection of children, in particular, has grown significantly in prominence. In the United States for example, President Clinton in 1997 issued Executive Order 13045, Protection of Children From Environmental Health Risks and Safety Risks.
This Executive Order was endorsed with amendments in 2003 by President Bush.
There has also been a great deal of progress in radiation protec-tion. The International Commission on Radiological Protection (ICRP), the US..

19 October 2006 In 2005, the Committee to Assess Health Risks from Exposure to Low Levels of Ionizing Radiation (National Research Council of the National Academies) issued a report that concluded that women have a 52 percent greater chance than men of getting cancer from radiation exposure. Seven years ago, the Environmental Protection Agency had reached similar conclusions. Yet, much radiation protection regulation is still stuck in the past - its "reference" person is a man.
Consider RESRAD, the government's software for calculating radiation doses from residual radioactivity in the soil. It is used for setting maximum limits for residual radioactivity as part of the decommissioning of radioactively contaminated sites, including the sites in the Department of Energy's nuclear weapons complex. Hundreds of billions will have been spent before the remediation is complete. RESRAD is very useful, but it has one major problem: its computations of radiation dose are based on "Reference Man,"
defined as a young adult, "Caucasian" male, who is "Western European or North American in habitat and custom." That is the definition generally used for "Reference Man."
It is clear that a central principle of environmental health protection -protecting those most at risk- is missing from much of the U.S. regulatory framework for radiation. For instance, women's higher cancer risk per unit of radiation exposure is not properly reflected in current regulations. Neither is the possibility of early miscarriages or fetal malformations potentially caused by radiation exposure.
Radiation standards generally specify a maximum allowable dose or a maximum contaminant limit, but these are derived numbers based on an underlying notion of maximum fatal cancer risk that any individual in the exposed population would suffer. The use of Reference Man to derive the dose limit means that the cancer risk for women would be considerably higher than that claimed as the maximum target value in the regulation. It also means that the diet of many Native Americans, such as the Yakima in Washington state, or of African Americans along the Savannah River in Georgia and South Carolina, that relies much more on fishing than considered normal for a White "Reference Man." would not be taken into account in radiation protection.
Contrary to Executive Order 13045, Protectionof ChildrenFrom EnvironmentalHealth Risks and Safety Risks, signed by President Clinton in 1997 and endorsed with amendments in 2003 by President Bush, agencies of the government allow corporations to ignore children. Consider, for instance, a remarkable official opinion from the Nuclear Regulatory Commission to Connecticut Yankee Atomic Power Company
[CY], written in 2001, that allowed the company to argue that a "white male, age 20-30" should be the basis for its calculations. And it explicitly allowed the company to argue that "our regulations prohibit
considering doses to children" despite the fact "the plain language of the regulation itself does not restrict the terms 'critical group,' 'individual,' or 'human being' to mean any specific age, race, or gender."'
The NRC permitted Connecticut Yankee to argue along these lines because the basic underlying document governing the regulations is the EPA's Federal Regulatory Guidance report number 11 (FRG 11), which is based on Reference Man, the young White male. We believe that the inclusion of children in radiation protection should not be optionaL Finally, the embryo/fetus, which is, in many ways, the most sensitive to radiation in terms of non-cancer health risks, is excluded from the regulatory scheme, except for protection of pregnant women in radiation-controlled work places after a voluntary declaration of pregnancy. Even there, the maximum allowable dose to the embryo/fetus, 500 millirem, is five times greater than best practices in Europe, for instance, in Germany. Also unlike Germany, there is no U.S. requirement to protect breastfeeding women from contact with significant radioactive contamination in the workplace after she declares that she is breastfeeding.
There is a need to consider the specific non-cancer health risks posed by certain radionuclides, both because of their nature and their widespread prevalence in the nuclear industry. Tritium, which is discharged into waterways in the form of radioactive water, including sources drinking water, from nuclear power plants and some nuclear weapons plants, crosses the placenta. It may increase the risk of early failed pregnancies or malformations. Similarly, strontium-90, concentrates in the red bone marrow, which is the source of stem cells for the immune system. Therefore, harm at the stage of rapid development of fetal and children's bones may create the potential for a wide variety of health problems. Such non-cancer effects are not well-understood, especially at low radiation doses; much less are they the concern of radiation protection regulations. Laboratory experiments, many done at the Armed Forces Radiobiology Research Institute, indicate that uranium, including depleted uranium, may be neurotoxic and may cross the placenta.
It may act in the body like lead, but with the harm compounded by radioactivity. While these effects have not been confirmed at low levels of exposure, there is significant cause for concern and reason for the exercise of precaution in regulation. It would be tragic, if, having the knowledge that we do, radiation protection regulations allowed the potential problem to grow, as society did with lead in gasoline for decades.
In sum, while much progress has been made in radiation protection since the late 1950s, there are still vast gaps, many of which go back to the use of Reference Man. It is time to retire him. Others are related to the lack of consideration to non-cancer health effects.
Finally, estimation of health risk, as expressed in regulations, is generally confined to assessment of one chemical at a time or to radiation. Combined radiation and chemical exposures are rarely considered in research and are absent from regulatory framework. This is partly because research into combined effects if difficult, but it is also because the regulatory concepts used in the two fields are somewhat different.
The report we are making public today, Science for the Vulnerable, is designed to provide the scientific foundation for a broader and deeper consideration of how environmental health standards should be set The coalition we are forming today will educate the public at large regarding the variety of environmental health risks we face and how they may be reduced. Among other things, we are asking President Bush to issue an Executive Order for executive branch agencies to review their definitions of reference persons and change them as needed to protect those most at risk.
Our initial list of signatories includes people from many backgrounds and a large variety of organizations, from public health to religious to Native American, to environmental to academic to elected officials to mothers concerned about the safety of breast milk. I sent the letter to President Bush yesterday, on behalf of the signatories. We are hopeful that President Bush will give the matter of strengthening the framework of environmental health protection his attention with the speed it deserves.

D.C., October 19, 2006: A broad coalition of scientists, physicians, cancer prevention leaders, children's health organizations, environmental justice advocates, and women's groups today launched a national campaign to shift the basis of many U.S. radiation health protection standards from an adult "Caucasian" male model, called "Reference Man," to those most at risk, specifically including
&hildrnand pregnant women..
The coalition is urging President Bush to direct all federal agencies - including the Department of Energy, the Nuclear Regulatory Commission, the Environmental Protection Agency, and the Food and Drug Administration - to review their exposure standards. A new report, produced by the institute for Energy and Environmental Research (JEER), Science for the Vulnerable: Setting Radiationand Mutiple
,xpwsure E.nvironmental ealthk &wkPad & to Protect7Those Most at Riak forms the scieinifio basis of the campaign.
Many federal radiation protection standards, such as limits on how much residual radiation will be allowed in contaminated soil, are based on "Reference Man," a hypothetical adult "Caucasian" male who is 20 to 30 years old, weighs 154 pounds, is five feet seven inches tall, and is "Western E3uropean or North American in habitat and custom." However, other groups, including women, children, and the embryoffetus, am often more sensitive to the hanmful effects of radiation or toxic materials.
"A central principle of environmental health protection - protecting those most at risk - is missing from much of the U.S. regulatory framework for radiation," said Arjun Makhijani, Ph.D., president of lEER and co-author of the report. *Womeens higher cancer risk per unit of radiation exposure is not properly reflected in current regulations. Neither is the possibility of early miscarriages or fetal malformations potentially caused by radiation exposure."
The reportzontains a Ae.ailed Iiscussion of the higher risks to women, and mpecially to ferule children, of certain kinds of cancer, notably thyroid cancer. A female infant drinking contaminated milk is a hundred times mome at risk of thyroid cance than an adult ntal; according to the report. For the same amount of radiation dose, women have a 52% greater chance of getting cancer. It also notes that water made radioactive with tritium crosses the placenta and affects the developing embryo/fetus, and can cause early failed pregnancies as well as malformations. These health risks are not part of regulatory considerations currently despite the fact that tritium discharges are occurring from both nuclear power plauts and some nuclear weapom facilities, such as the Savannah River Site.
"A considerable and growing body of evidence indicates that exposure to radiation and synthetic chemicals is contributing to increasing rates of breast cancer in the U.S. and other industrialized eourries," taid Jeane Rizza, R.N., executive diretor of the Brest Cencer Fud. "Ifwe change our safety standards to specifically protect women and girls, we will spend less time, money and heartache treating diseases caused by environmental expumes."
The report provides a model for assessing some of the simpler combined effects of chemicals and radiation, including when they reinforce one another. "It is important to consider how radiation and chemicals can act together to promote cancer," said Dr. Michael Thome, a British consultant to lEER, and a co-author of the report. "Exposure to ionizing radiation could increase the number of cells that have the potential to proliferate to form breast cancers later in life and exposure to chenmicals that modify estrogen levels could preferentially enhance the survival of such cells."
"Rapidly increasing rates of cancers and other illnesses related to radiation and hazardous toxic chemicals in our environment are creating a population of grandparent-less families in our environmental justice communities," said LaDonna Williams, Executive Director of People for Clhildre's Health &
Environmental Justice. "The federal government must act now by adopting more protective standards to reverse this negative trend that is having devastating impacts on our families, health, lives and envirom-ent."
"ive never known a woman to give birth to a full-grown, 154-pound 'Reference Man'," observed Mary Brme, Co-founder of MOMS, Making Our Milk Safe. "Pregnant women, developing children, and infants require and deserve a higher degree of protection than the current regulatory framework provides.
The JEER report provides realistic and inclusive guidelines for protecting the most -vulnerable among us."
The report points out that the concepts to solve much of the problem already exist in the form of the "nmaximally exposed individual" and of the "critical group" but have not been widely applied. The government's model for setting residual radioactivity standards for cleaning up radioactively contaminated sites, RESRAD, depicts a family on the frontpanel display, but its standard model converts contamination to radiation dose only for "Reference Man! In the c ntext of clean-up of Department of Energy sites, the risk to a pregnant woman farmer, the fetus, and her children should be evaluated, rather than only Reference Man. The most sensitive should be protected.
The report makes specific recommendations regarding strengthening workplace protections. Besides abandoning "Reference Man" and replacing him with the most vulnerable population subgroup, the report makes specific recommendations regarding wotk-placeprotection for the embryc/ferus. The US. standard for workplace radiation exposure is five times more lax than that in Germany, for instance. The maximum exposure should be lowercd to 100 millirem per year, from the present 500. The rpo= also recommends that the United States adopt a rule for radiation controlled workplaces to protect women ftmn bodily contamination, once women inform their employers that they are breastfecding. Unlike Eupe, no such protection exists in the United States today.
in view of the potential non-cancer health risks of tritium to the embryo!fetas and pregnant women, which are absent from the framework ofpresent radiation protection or drinking water regulations, the report recommends consideration of restricting discharges so that offsite surface water has no more than 500 picocuries per liter of tritium, which is a standard that has already been adopted by the State of Colorado for the environs of the Rocky Flats Plant, near Denver. The U.S. Department of Energy agreed to this limit as a site-specific standard in the clean-up of Rocky Flats, which has now been decommissioned.
The present national drinking water maximum contaminant limit for tritium is 20,000 pieowuries per liter.
The report recommends an analysis to determine the feasibility of a limit of 500 picocuries per liter at all nuclear power and nuclear weapon sites, including wnediation of those sites.

NRC gets earful from lawmakers on Vermont Yankee license renewal By David Gram, Associated Press Writer I February 27, 2007 MONTPELIER, Vt. -Vermont lawmakers asked pointed questions and voiced strong criticism Tuesday in a meeting with regulators reviewing Vermont Yankee's request for a 20-year license extension.
The legislators, mostly from Windham County where the plant is located, voiced frustration that the U.S. Nuclear Regulatory Commission license renewal process is limited to making sure components at the 35-year-old Vernon reactor can withstand 20 years of operation beyond the plant's scheduled 2012 license expiration, and the environmental impacts of that continued operation.
Not up for consideration are Issues ranging from the possibility and consequences of a terrorist attack on the plant to the wisdom of generating highly radioactive waste for an extra 20 years when the federal government has yet to open a site to dispose of it.
'Weve had promises for years from the federal government that we were going to have a site of permanent storage (of high-level waste)," said state Rep. Virginia Milkey, D-Brattleboro, "and I think that date has gone by."
Richard Emch, the NRC's environmental project manager for the Vermont Yankee review, repeatedly said the agency was looking for "new and significant information" relating to the safety of Vermont Yankee's electrical, mechanical and other systems, and environmental impacts, for example, to fish species In the Connecticut River.
Rep. Sarah Edwards, P-Brattleboro, said the failure of the federal government to come up with a long-promised site for high-level waste was a new development since Vermont Yankee was last up for license review in 1972. "isn't this new and significant information?" she asked.
Vermont passed a law last year gMng the Legislature veto power over relicensing Vermont Yankee; it must decide by July 2008. The law spells out a process that is to include three public hearings.
Its unclear what would happen if the NRC approves the license extension - officials said it had approved about 50 at plants around the country and denied none - and Vermont decides against it.
In an interview, NRC spokesman Neil Sheehan said if Vermont tried to block the license extension, it could risk litigation because federal law puts the NRC solely in charge of nuclear plant safety.
In another development, an NRC panel has ruled that Vermont Yankee doesn't need test its ability to shut down from full power despite a 20 percent increase in output.
Monday's ruling from the NRC's Atomic Safety and Ucensing Board rejected a formal contention about the power boost brought by the nuclear watchdog group New England Coalition. It ends the last outstanding bit of regulatory business connected with the increase, which Vermont Yankee completed last spring.
The coalition cited recommendations from NRC staff that as a general rule, plants contemplating such an increase in power output conduct one or both of two types of reactor "scram" - or immediate shutdown - from full power.
The NRC panel said Vermont Yankee owner Entergy Nuclear had provided enough information based on experience at other nuclear plants around the country to avoid the need for either type of test at the Vernon reactor.
