Point Lapses in Radiation Monitoring:
Entergy cites “heavy work load” and “limited
resources” for delays in repair
Seven instruments to measure Indian Point Nuclear Power Station’s
radiation releases failed and were out of service for greater
than 30-day periods during 2010, according to the plant’s
annual radiation effluent monitoring report issued on April
Several of the failed monitoring devices are located at critical
pathways where airborne radioisotopes – byproducts of
nuclear fission – are released into the environment.
The seven monitors are identified as the Unit 2 plant vent
process flow rate indicator, Unit 3 primary water storage
tank level instrument, two Unit 3 steam generator blowdown
monitor, Unit 2 radioactive machine shop vent process flow
meter, Unit 3 plant vent noble gas monitor and the Unit 1
stack vent noble gas monitor.
The Unit 1 stack vent is a pathway for release to the air
of noble gases which decay to strontium-90 and strontium-89
and other radioisotopes. The report states:
“The monitor’s memory failed during calibration
[on December 12, 2010]. After repair, an independent failure
occurred with a non-required sub-channel that rendered the
noble gas channel inoperable. Prioritization, high work load,
limited resources, flooding in the work area, and an ongoing
modification to retire the superfluous (troubling) channel
combined to delay repairs, which are expected in April, 2011.”
The Unit 3 plant vent noble gas monitor is a pathway for release
to the air of noble gases which decay to strontium-90 and
strontium-89 and other radioisotopes. The report states:
“This backup plant vent monitor’s detector required
repair. Due to the primary instrument being in service and
unaffected, a high work load, and limited resources, repair
and recalibration of the [device] was given secondary prioritization.”
A Unit 3 steam generator blowdown monitor became inoperative
on November 8, 2010 and remained inoperative into the new
year. The report states:
“Difficulty in accessing and repairing the [faulty]
valve [that led to disabling of the monitor] drove a decision
to leave this line isolated until the upcoming refueling outage.”
A second Unit 3 steam generator blowdown monitor was out of
service for 33 days. The report states:
“The control room lost communication with monitor in
the field. Continuous work to repair was not possible, due
to prioritization established with high work load and limited
resources. Because it could not be worked continuously, multiple
teams were used to troubleshoot. The complexity of the system
and lack of continuity of repair teams challenged timely resolution
. . .”
The Unit 2 plant vent process flow rate indicator was out
of service from October 2009 until March 28, 2011 - a total
of 18 months.
The Unit 3 primary water storage tank level instrument was
out of service from mid-December 2009 to January 21, 2010
due to a succession of failures, including failure of a freeze
protection strip heater, failure of a new instrument, and
a calibration failure.
The report does not identify radiation effluent monitoring
equipment failure that lasted fewer than 30 continuous days.
Louise Reiss, Pioneer Who Exposed Levels of Strontium-90
in Baby Teeth from Atomic Fallout
The Mothers Milk Project honors Dr. Louise Reiss, who directed
the study of hundreds of thousands of baby teeth for strontium-90
levels during the period of atmospheric nuclear weapons testing
in the 1960s. Her pioneering work help bring about a ban of
nuclear testing in the atmosphere.
Dr. Reiss died on January 1, 2011 at age 90.
Her obituary appears here in The New York Times:
Dr. Reiss’ study led to conclusions that radioactive
fallout from nuclear fission was entering the food supply
and being taken up by the bones and teeth of human babies.
Strontium-90, a byproduct of nuclear fission from bombs as
well as nuclear power plants, mimics calcium in its chemical
properties and is a carcinogen.
The study found that children born in St. Louis in 1963 had
50 times as much strontium-90 in their teeth as children born
in 1950, before most of the atmospheric nuclear testing occurred.
Her work is being carried on by the Radiation and Public Health
RPHP executive director Joseph Mangano published results of
a new study last month in The International Journal of Health
The study found that donors of teeth from the original project
who died of cancer by age 50 had more than twice the average
strontium-90 levels of donors who were healthy at age 50.
The finding suggests a correlation between higher levels of
strontium-90 and an increased cancer risk.
11, 2010, Indian Point Unit 2 tripped
Point nuclear plant officials say amount of radioactive steam
released was 'Insignificant'
That cloud spewing
out of the Indian Point nuclear plant last month wasn't a smoke
signal - it was radioactive steam.
For two days starting Nov. 2, an estimated 600,000 gallons of
boiling, radioactive water escaped through a valve that was
stuck open in the Unit 2 reactor of the nuclear power plant
The superheated water instantly turned to steam and spread out
over the lower Hudson Valley in a cloud containing tritium,
a cancer-causing radioactive isotope.
A spokesman for plant operator Entergy said the company wasn't
concerned about the amount of radioactivity released into the
"The steam was from a non-radioactive secondary system,"
said spokesman Jerry Nappi, "that contains slight amounts
of tritium and is insignificant."
The accidental release, however, prompted an inspection from
the regional office of the Nuclear Regulatory Commission.
According to NRC spokesman Neil Sheehan, the commission ordered
a report from Entergy that is due within 60 days. The report
will detail exactly what happened during the steam release.
"We will be documenting our own findings in an inspection
report covering plant activities for the fourth quarter of 2009.
It will be due out in late January," said Sheehan.
According to Kevin Mangan, a senior NRC inspector on site at
Indian Point, the water was highly pressurized at 750 pounds
per square inch before it jettisoned for about 42 hours.
It took two days for plant owner Entergy to realize the valve
was leaking before the plant automatically shut down.
Although Entergy officials dismissed the seriousness of the
incident, operations at the plant were abruptly halted for four
Meanwhile, on Wednesday, a test of several emergency sirens
that warn of an accident at Indian Point performed poorly, according
to the NRC.
There are 172 sirens within 10 miles of the Buchanan based plant,
and 37 of them failed to respond to a radio signal.
The new $30 million emergency siren system was installed last
year to alert some 300,000 residents living within a 10 mile
radius if the plant has an accident.
According to the NRC, in Wednesday's test, one out of every
16 sirens in Putnam County failed, rating the utility company's
performance at 78%. The NRC requires a 90% average for emergency
The last test for the Indian Point sirens was in October, when
all the sirens scored perfectly.
Entergy has applied to the NRC for a new operating license that
would keep its two reactors running for an additional 20 years.
Indian Point earns about $1 million a day for Entergy.
New report shows newborn
hypothyroidism rate near Indian Point is 92% above US
Dear Friends:This new report, which will be on our web site (www.radiation.org)
in a few days, shows the rate of hypothyroidism in newborns from Orange,
Putnam, Rockland, and Westchester counties is 92% above the U.S. rate.This
finding corresponds to the article released last week showing the
thyroid cancer incidence rate is 66% above the U.S. in these counties.As
usual, I encourage all of you to utilize this information in your
efforts on the future of Indian Point. It is critical that the public
and officials be aware of health risks posed by the plant.Best wishes,

Joseph Mangano, Executive Director
Radiation and Public Health Project
November 25, 2009Background Hypothyroidism and Radiation Exposure.
Hypothyroidism is a disorder of the thyroid gland marked by low levels
of thyroid hormone (thyroxine) and high levels of Thyroid Stimulating
Hormone (TSH).For years, scientists have established a causal relationship
between radiation exposure and hypothyroidism. In particular, radioactive
iodine (which seeks out the thyroid gland, and destroys cells) is
linked with the disease.Residents of the Marshall Islands were exposed
to high levels of fallout from atomic bomb tests during the 1950s.
Subsequent studies documented a number of Marshallese children with
hypothyroidism, also known as cretinism. Because there was no treatment
for the disease at the time, and because thyroid hormone is critical
to physical and mental growth, these children often were dwarfs suffering
from mental retardation.Low doses of radioactive iodine have also
been linked with in high hypothyroidism rates. In the nine months
after the Three Mile Island accident in 1979, there were 9 cases of
the disease among Pennsylvania newborns. Eight (8) of the 9 were babies
born to the east (downwind) of the Three Mile Island plant.Screening
Newborns for Hypothyroidism, and Rising Rates.
Hypothyroidism can be controlled by proper administration of thyroid
hormone to the patient. Because of the vital role played by the thyroid
gland in physical and mental development of the young, newborns have
been screened for the disease for many years. The practice became
widespread in the late 1970s with the invention of a technique that
only requires drawing a single drop of blood from the baby?s heel.All
50 U.S. states now have mandatory newborn screening programs for a
variety of disorders, including hypothyroidism. National rates have
been rising during the past several decades. One recent medical journal
article documented a 73% rise in the U.S. rate from 1987 to 2002.
(1) This trend is parallel to the sharp increase in the U.S. thyroid
cancer (all ages) rate, which rose 155% from 1980 to 2006. It is unclear
whether the increase in newborn hypothyroidism is due to better detection
or other factors.Hypothyroidism in Newborns Near Indian Point.
In New York State, mandatory screening for newborn hypothyroidism
began in 1978. An article by administrators of the program showed
that the state rate rose 138% from 1978 and 2005 (1).Because U.S.
atomic bomb tests above the ground ceased in 1963, and all tests ceased
in 1992, the only current source of environmental radioactive iodine
is emissions from nuclear power plants. The oldest and largest plant
in New York State is Indian Point. One reactor at the site ran from
1962-1974, while the other two started in 1973 and 1976.According
to official records maintained by the U.S. Nuclear Regulatory Commission,
Indian Point emitted the 5th highest amount of airborne radioactive
iodine of all U.S. nuclear plants from 1970-1993. The Indian Point
total of 17.5 curies exceeds the official total of 14.2 released during
the Three Mile Island accident in 1979. (2)Four New York counties
flank Indian Point, and nearly all residents of these counties live
within 20 miles of Indian Point. The New York State Newborn Screening
Program provided numbers of newborn hypothyroidism cases for each
of these counties for each year between 1997 and 2007. Table 1 presents
rates of newborn hypothyroidism for these counties compared to the
United States.Table 1

(live births). Cases represent confirmed cases of primary hypothyroidism
in newborns.Results show that the 1997-2007 four-county newborn hypothyroidism
rate was 92.4% greater, or nearly double, the U.S. rate, based on
208 confirmed cases in the 11-year period. Each county?s rate exceeds
the national rate, and both Rockland and Westchester rates were more
than double the U.S.. The highest rates are in the most recent years;
the 2005-2007 local rate was 151.4% above the U.S.Conclusions.
Rates of newborn hypothyroidism in counties closest to the Indian
Point nuclear plant are roughly double the U.S. rate. While many factors
may account for this pattern, none are obvious. The fact that Indian
Point has released more radioactive iodine into the air than most
U.S. nuclear plants suggests that these releases may represent one
causal factor.Results are consistent with the recent journal article
showing the local rate of thyroid cancer is 66% greater than the U.S.
rate. (3) Exposure to radioactive iodine raises risk of both thyroid
cancer and hypothyroidism.As the U.S. Nuclear Regulatory Commission
considers a proposal to extend the Indian Point licenses for 20 years,
it is important that information such as local rates of newborn hypothyroidism
be made available to the public and to decision makers.

PROGRAM TO TEST IF INDIAN POINT HAS HARMED THYROID GLANDS OF LOCAL
For immediate release Contact Joseph Mangano 609-399-4343 Sharon Cunningham
June 3, 2009 – A fast, inexpensive test that determines elevated
thyroid stimulating hormone, an indcator that the thyroid gland may
be under stress, will be available at a public event later this month.
The ThyroChek testing program will examine if persons living near
the Indian Point nuclear plant have higher than normal levels of TSH.
The test uses a drop of blood from a finger stick to determine whether
the level of thyroid stimulating hormone is normal, in just 10 minutes.
The test will be available at the Clearwater Festival in Croton-on-Hudson
the weekend of June 20-21. Screening Devices Canada, which manufactures
the FDA regulated test in California, will have professional staff
available to explain the importance of thyroid health, administer
the test, and provide results on the spot. The cost is $10.
The information from the two day testing program may provide information
on whether emissions from the Indian Point nuclear reactors are affecting
the thyroid glands of people who live in the vicinity. The percent
of tests indicating elevated TSH in local residents will be compared
with results of other populations living far from reactors. Indian
Point produces and emits radioactive iodine particles; when they enter
the body, they attack thyroid cells, leading to cancer and other problems
“ThyroChek is an easy way to study a serious public health issue,”
says Joseph Mangano, Executive Director of the Radiation and Public
Health Project. He adds there are no standard screening programs for
thyroid health in the U.S., even though the rate of thyroid cancer
has nearly tripled since 1980. Experts believe that hypothyroidism
rates have soared as well. No single blood test can determine thyroid
cancer but a TSH test may be used to evaluate the thyroid's activity
and test for hypothyroidism, a common disease of the thyroid. There
are about 30 million Americans with hypothyroidism, a disease that
if not detected and treated may lead to cardiac disease, reproductive
issues, mental health concerns, obesity and a variety of autoimmune
Official statistics indicate that the 2001-2005 thyroid cancer rate
in counties closest to Indian Point are nearly double the U.S., and
among the highest in the nation. The annual U.S. rate of 8.9 per 100,000
persons is exceeded in Rockland, Putnam, Orange, and Westchester Counties
(18.3, 18.0, 16.6, and 12.6, or 106%, 102%, 87%, and 42% higher).
About 300 residents in these counties are diagnosed with thyroid cancer
"As a local family practice physician, I see a high number of
people with thyroid disorders," says Susanne Saltzman MD. "When
I discovered that nuclear power plants routinely emit radioactive
iodine, which damages thyroid tissue, I became very concerned that
Indian Point might be contributing to the higher rates of thyroid
problems in the Hudson River Valley. Studies must be done to evaluate
health effects of living near and downwind from Indian Point."
Sharon Cunningham, president of Screening Devices Canada welcomes
the opportunity to test at the Clearwater Festival. “By providing
results on the spot, we will be able to educate on the importance
of thyroid health and how the environment can affect it. More about
thyroid health testing can be obtained from the company’s website,
Mangano says RPHP, which is a New York-based research group, plans
to analyze the data, and announce results in the near future. More
information on the Clearwater Festival is available at www.clearwater.org.
Mothers Milk Project
Launched to Sample Human and Dairy Milk
Within 50 Miles of the Indian Point Nuclear Power Station
For Release June 5, 2008/12 noon
Contact: Nancy Burton Tel. 203-938-3952/Cell203-545-9252 email: NancyBurtonCT@aol.com
mothers from three counties surrounding the Indian Point Nuclear Power
Station joined a press conference today to announce creation of the
Mothers Milk Project to sample human and dairy milk within 50 miles
of Indian Point in Buchanan, New York.
It is believed to be the first project to systematically sample human
milk from mothers living near a nuclear power plant to detect the
presence of radioactive contaminants released by the plant.
During routine operations, Indian Point is designed to release fission
byproducts into the air and water. One such radionuclide, krypton,
rapidly decays to strontium-90, a beta particle which mimics calcium
in its chemical composition. Strontium-90 is readily absorbed in bone
tissue and teeth. With a half-life (decay period) of 30 years, it
disrupts nearby cells and is known to cause leukemia, bone cancer,
diseases of the immune system and cancers of soft tissues such as
breast and lung. Children and developing babies are especially vulnerable
to its effects.
Indian Point once had a program to sample dairy cow milk from a farm
located within five miles of the plant, but abandoned the program
in 1991 when the farm ceased to milk cows. New York State stopped
its own monitoring for dairy milk near Indian Point at the same time.
Entergy, Indian Point's owner, conducts sampling for evidence of radioactive
contamination in the environment but in its annual reports filed with
federal and state regulators it states:
"There are no animals producing milk for human consumption within
five miles of Indian Point."
"Entergy has been overlooking a critical animal subspecies: women
who breastfeed their babies within five miles of Indian Point and
beyond," said Nancy Burton, co-founder of Mothers Milk Project.
"Our project will shine a light on this never-before sampled
population," Burton said.
Burton announced the formation of Mothers Milk Project with co-founder
Gail Merrill at Merrill's home in New Canaan, Connecticut.
The Mothers Milk Project will collect samples of breast milk - as
well as cow and goat milk - within a 50-mile radius of Indian Point.
Since emails were circulated during the past week, dozens of breastfeeding
women, from Brooklyn to Tarrytown NY, have responded with offers to
have their milk sampled.
The Project will collect 8-ounce samples monthly and divide them into
four parts: one for the New York State Department of Health, one for
Entergy, one for the Project's independent laboratory and one to be
retained by the Project for possible re-testing.
The Project has appealed to the New York Department of Health to resume
its own milk sampling program near Indian Point and has been informed
the matter is under consideration.
The project also contacted Entergy to request it resume milk sampling
but Entergy has not responded.
Entergy does carry out a milk-sampling program at four dairy farms
located near Vermont Yankee Nuclear Power Station near near Brattleboro,
"If Entergy can sample cow's milk in Vermont, why not human milk
near Indian Point with its population of 22 million people within
50 miles of the plant," queried Merrill.
Each breastfeeding donor will be asked to complete a simple confidential
questionnaire. Once results are received, they will be plotted on
a map and used to create a database for future comparison. The Project
will also sample for traces of Iodine-131, a carcinogen which disrupts
thyroid and endocrine function.
Burton said she was motivated to launch the Mothers Milk Project because
of her work as Director of the Connecticut Coalition Against Millstone,
a nuclear power plant near New London, Connecticut.
Poring over environmental reports filed by Dominion Nuclear Connecticut,
Inc., Millstone's owner, Burton learned that Dominion sampled goat
milk 5.5 north of Millstone and detected high concentrations of strontium-90
in the goat milk in 2001 and at other times.
Goat milk is considered a reliable indicator for the presence of radionuclides.
Also joining the press conference were a lactating goat, Cindy-Lu,
and her kids, Hannah and Henry, who will be part of the Project.
"Breatfeeding mothers and others are entitled to know if harmful
radioactive effluents are entering our milk supply," Burton said.
"We believe 'breast is best' and our babies should be protected
from insidious contaminants," she added.
Note to Editors: The Mothers Milk Project press conference will take
place on Thursday, June 5, at 12 noon at 227 Silvermine Road in New
